LT1764EFE-2.5#PBF

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

The LT1764EFE-2.5#PBF is a fixed-output low dropout linear regulator manufactured by Analog Devices Inc., providing a regulated 2.5V output with a maximum current of 3A. It operates within an input voltage range of 2.7V to 20V and features a typical dropout voltage of 340mV at full load. The device incorporates a shutdown pin for power management, reducing quiescent current to less than 1µA when disabled. It includes built-in protections against overcurrent, thermal overload, and reverse polarity conditions.
