The TLE4276GVATMA4 from Infineon Technologies is a robust single-output low dropout regulator delivering a fixed 20V output. It supports up to 400mA with a dropout voltage of just 0.5V at 250mA. The quiescent current is a low 200 µA, and PSRR is 54dB at 100Hz, making it suitable for automotive and industrial applications. Packaged in a PG-TO263-5-1 (D2PAK), it offers excellent thermal performance.
- High Voltage Output: 20V fixed output is ideal for automotive and industrial 24V systems.
- Low Dropout: 0.5V at 250mA ensures efficient operation even with marginal input margins.
- Excellent Ripple Rejection: 54dB PSRR at 100Hz filters mains and alternator noise.
- Automotive-Grade Robustness: PG-TO263-5-1 package handles high power dissipation in harsh environments.
Automotive ECU Power Supplies
With a 20V output and 400mA capability, this LDO is ideal for powering automotive ECUs that require a stable 20V rail from a 12V battery system.
Industrial 24V Bus Regulation
It can step down a 24V industrial bus to a clean 20V supply for sensors and actuators, with 54dB PSRR at 100Hz rejecting mains ripple.
Telecom Line Cards
The 20V output is suitable for powering line driver ICs in telecom equipment, providing a low-noise supply for analog front-ends.
