LT3063HDCB#TRPBF

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

The LT3063HDCB#TRPBF is a micropower, low dropout linear regulator from Analog Devices Inc. It operates over an input voltage range of 1.6V to 45V and supplies up to 200mA of output current with a typical dropout voltage of 300mV. The device features a quiescent current of 45μA and shutdown current below 3μA. It includes an NMOS pull-down for active output discharge when the SHDN pin or input is driven low. Internal protections encompass reverse-battery protection, reverse-current protection, current limit foldback, and thermal shutdown. The H-grade variant supports an operating junction temperature range of -40°C to 150°C.
