LT3055IMSE-3.3#TRPBF

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

The LT3055IMSE-3.3#TRPBF is a micropower, low noise, low dropout voltage linear regulator from Analog Devices. It provides a fixed 3.3V output with a maximum current of 500mA and a typical dropout voltage of 350mV. The device features a ±45V input voltage rating, precision programmable current limit accurate to ±10%, and comprehensive diagnostic functions including fault indicators and temperature monitoring. Output noise is reduced to 25μVRMS in a 10Hz to 100kHz bandwidth using a 10nF bypass capacitor. It operates within a junction temperature range of -40°C to 125°C and is housed in a 16-lead plastic MSOP package.
