LR1965 - LOW DROPOUT REGULATOR

Description

The UTC LR1965 is CMOS-based positive voltage and a very low dropout regulator IC that minimum input voltage is 2.5V and is capable of delivering the continuous output load current up to 1.5A.

Features

  • of low dropout (maximum 300mV at 1A), a very low quiescent current (typically 300uA at 0.1A) and very high PSRR up to 86dB at 1A load current. The output voltage can be set from 0.5V to (VIN - VDRP) with an external resistor divider and it has ±2% accuracy through all temperature ranges include the line as well as load variations. It is allowed to use a small 4.7μF MLCC input and output capacitor to deliver the current with the stable operation. Built-in Soft-Start function reduces the inrush cu.
