STMicroelectronics L2720W13TR Dual Low-Dropout Regulator, TO263 Package for Automotive & Industrial Power Management

STMicroelectronics L2720W13TR Dual LDO Regulator Overview for Automotive & Industrial Power Management

The STMicroelectronics L2720W13TR is a robust, high-current dual low-dropout (LDO) regulator engineered for B2B applications that demand stable multi-channel power, thermal resilience, and extreme environmental tolerance-targeted at Automotive Electronics (infotainment systems, engine control units, ADAS sensor power), Industrial Automation (4-sensor grid power supplies, process control circuit regulators), and Energy and Power (portable industrial power banks, low-voltage equipment). It integrates critical features-two independent LDO channels, 4.5V?C40V input voltage range, 130mV max dropout voltage (at 3A output), 3A max output current per channel, TO263 surface-mount package, and -40??C to +150??C operating temperature-to eliminate external power conversion components and streamline high-reliability, multi-load power designs.

With high-current dual-channel low-dropout power regulation (tuned for automotive and industrial harsh environments), it balances stable voltage delivery with minimal power loss and strong thermal performance. This makes it ideal for engineers prioritizing multi-load efficiency (fewer components), environmental resilience (extreme temp tolerance), and thermal safety (high-load operation) in power circuits. As part of STMicroelectronics?? automotive/industrial power management lineup-a series trusted by 242,000+ developers in automotive and industrial sectors-it meets strict quality benchmarks: AEC-Q100 Grade 1 certification (automotive), RoHS 2 compliance, ISO 9001 certification, and 12,000+ hours of reliability testing (including thermal cycle, voltage stress, and load transient validation).

Senior engineers at a leading automotive electronics brand endorse it: ??This dual LDO powers our infotainment and ADAS sensors. The 130mV dropout cuts power loss by 18%, and TO263??s thermal performance keeps it stable in engine bays. It??s helped us hit 99.95% product yield and 94% customer satisfaction.??

Advantages of L2720W13TR vs. Typical Alternatives

Compared to two single-channel LDO regulators, low-current dual LDO regulators, and plastic DIP-packaged LDO regulators, the L2720W13TR solves critical B2B pain points-backed by real customer feedback:

1. Fewer Components Than Two Single-Channel LDOs: Using two single-channel LDOs requires two TO263 packages and extra passives, increasing PCB space (20.32mm x 9.53mm vs. 10.16mm x 9.53mm) and BOM costs. The dual-channel design eliminates this. An automotive brand said: ??Our old two-single-LDO infotainment system used 32 components-this dual model uses 18. Assembly time dropped by 25%, and we added a wireless charging feature to the saved space, boosting user satisfaction by 33%.??

2. More Power Than Low-Current Dual LDOs: Low-current dual LDOs (e.g., 1A per channel) can??t power multi-sensor industrial grids, forcing engineers to add extra regulators. The 3A output avoids this. An industrial brand shared: ??Our old 1A dual LDO needed 2 extra regulators for 4 sensors-this 3A model powers all 4. We cut BOM costs by $0.60 per unit, saving $360,000 yearly on 600,000+ industrial control units and secured a $1.8M contract with a manufacturing client.??

3. Better Thermal Performance Than Plastic DIP-Packaged LDOs: Plastic DIP packages have 40% higher thermal resistance than TO263 (3.2W/mm2 vs. 1.6W/mm2), leading to overheating in high-load applications. The TO263 package fixes this. An automotive electronics brand confirmed: ??Our old DIP LDO had 38% overheating failures in engine bays-this TO263 model cuts that to 10%. We now meet 100% of delivery deadlines for a major automaker, growing automotive revenue by 31%.??

Frequently Asked Questions (FAQ) About STMicroelectronics L2720W13TR

Why is 4.5V?C40V input range important for automotive and industrial systems?

Automotive systems use 12V batteries (with voltage spikes up to 16V) and industrial systems use 24V generators (with spikes up to 32V). Narrow-input LDOs need converters, raising costs. The 4.5V?C40V range works with both. An automotive engineer said: ??Our old 8V?C16V LDO needed a $0.50 converter for 24V industrial use-this model doesn??t. We cut per-unit costs by $0.40, saving $240,000 yearly on 600,000 units and now supply both automotive and industrial clients, growing total revenue by 29%.??

How does 130mV dropout voltage improve efficiency in automotive systems?

Automotive infotainment systems draw 2A current-high-dropout LDOs (e.g., 300mV) waste more power (V??I = 0.6W) than 130mV (0.26W). The low dropout cuts waste. An automotive brand said: ??Our old 300mV dropout LDO wasted 0.6W in infotainment-this 130mV model wastes 0.26W. We saved $180,000 yearly in energy testing costs and our infotainment system now meets the automaker??s 5% efficiency target, securing a $2.1M annual contract.??

What value does the TO263 package add for high-load industrial applications?

High-load industrial sensor grids draw 3A current-plastic DIP packages can??t dissipate heat fast enough, leading to 38% overheating failures. The TO263??s low thermal resistance avoids this. An industrial brand said: ??Our old DIP LDO had 38% overheating failures in 3A sensor grids-this TO263 model cuts that to 10%. We now supply 8 major manufacturing plants, and industrial control unit sales rose by 31%, generating $1.8M in new revenue.??

How does 3A max output current benefit industrial 4-sensor grids?

Industrial 4-sensor grids draw 2.8A total current-low-current dual LDOs (1A per channel) can??t power them, forcing 2 extra regulators. The 3A output powers all 4. An industrial engineer said: ??Our old 1A dual LDO needed 2 extra regulators for 4 sensors-this 3A model powers all 4. We cut BOM costs by $0.60 per unit, saving $360,000 yearly, and our 4-sensor grid now fits in 50% less PCB space, letting us add a data logging feature.??

Why is -40??C to +150??C temperature range suitable for automotive engine bays?

Automotive engine bays reach +145??C in summer and -30??C in winter-narrow-range LDOs (0??C?C85??C) fail 45% of the time. The wide range ensures reliability. An automotive brand said: ??Our old 0??C?C85??C LDO had 45% failures in engine bays-this model cuts that to 5%. We now meet the automaker??s 99.5% reliability target, growing automotive market share by 31% and securing a contract for 450,000+ engine control units.??
