TLE42712GATMA1

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TLE42712GATMA1 is a fixed-output low-dropout (LDO) linear voltage regulator from Infineon's OPTIREG series. It provides a stable 5 V output with a maximum continuous current of 550 mA. The device operates within an input voltage range of 6 V to 40 V and features a typical dropout voltage of 350 mV at full load, with a maximum of 700 mV. It includes integrated protection against overcurrent, overtemperature, overvoltage, reverse polarity, and short circuits. The regulator offers high power supply rejection ratio (PSRR) of 54 dB at 100 Hz and maintains a low quiescent current of 6 µA. It is qualified to AEC-Q100 standards for automotive applications and operates across a junction temperature range of -40°C to +150°C.
