LT1964ES5-BYP#TRMPBF | 5.0V Ultra-Low Noise LDO Regulator with Bypass

Product Overview

     The LT1964ES5-BYP#TRMPBF is a high-performance low dropout (LDO) linear regulator delivering a fixed 5.0V output with ultra-low noise and high power-supply rejection ratio (PSRR). Featuring an external BYP bypass pin, the device significantly reduces output noise and improves transient response. It is designed for noise-sensitive analog and mixed-signal systems such as precision data converters, RF front ends, and industrial sensors. Stable operation with low-ESR capacitors and robust protection features make this regulator ideal for demanding power-clean applications.
