LT3065MPMSE-1.2#PBF

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

The LT3065MPMSE-1.2#PBF is a micropower, low noise, low dropout voltage linear regulator manufactured by Analog Devices Inc. It operates over an input voltage range of 1.6V to 45V and supplies 500mA of output current with a typical dropout voltage of 300mV. This specific variant provides a fixed regulated output voltage of 1.2V. The device features programmable precision current limit accurate to ±10% via a single external resistor, along with a power good flag indicating output regulation. It utilizes a single external capacitor for soft-start and noise reduction, ensuring stability with low ESR ceramic capacitors. Internal protection includes thermal limiting, reverse battery protection, and reverse output protection.
