LT1964ES5-BYP#TRPBF

High PSRR, Low Noise 5.0V LDO with Bypass Pin for Precision Power Rails

Product Description

Product Overview

The LT1964ES5-BYP#TRPBF is a high-performance low dropout (LDO) linear regulator delivering a fixed 5.0V output with ultra-low noise and excellent power-supply rejection ratio (PSRR). Featuring a BYP bypass pin to further reduce output noise and improve transient response, this LDO is ideal for powering sensitive analog circuits, precision data converters, RF modules, and other mixed-signal systems. Its stable operation with low-ESR capacitors and robust protection features make it a reliable choice for industrial and communication applications.
