The LM2940LD-5.0/NOPB from Texas Instruments is a robust 5V LDO regulator capable of delivering 1A. With a wide input range up to 26V and 1V dropout, it suits automotive and industrial environments. The 8-WSON package offers a compact solution with good thermal performance.
- Wide Input Range: Handles 6V to 26V, ideal for automotive and industrial power rails.
- High Output Current: 1A supports multiple loads and peripheral ICs.
- Good Ripple Rejection: 64dB at 120Hz ensures clean output for analog circuits.
- Compact WSON Package: 4x4mm footprint saves PCB space while maintaining thermal dissipation.
Automotive ECU Power
Regulate 5V for microcontrollers and sensors in engine control units. The wide input range handles load-dump transients up to 26V.
Industrial Control Systems
Provide a stable 5V rail for PLCs and industrial sensors, with 64dB PSRR rejecting 120Hz noise from rectified mains.
Telecom Infrastructure
Power line cards and base station controllers from a 12V bus. The 1A output supports multiple logic ICs and interface transceivers.
Battery Charger Circuits
Use as a post-regulator after a switching charger to provide clean 5V for charging logic and fuel gauges.
Test & Measurement
Supply 5V to precision ADCs and DACs in bench instruments. The low dropout ensures stable operation even with input ripple.
Consumer Electronics
Power set-top boxes and gaming peripherals from a 12V adapter, providing a clean and regulated 5V rail.
