UM154xxS Overview

UM154xxS Ultra-Low Quiescent Current Linear Regulator

Features

Ultra-low Quiescent Current Linear Regulator

The UM154xxS series are ultra low quiescent current low dropout linear regulators designed for low power portable applications. The range of output voltage is from 1.3V to 5.0V while operated from 2.2V to 5.5V input. The EN function of UM154xxS can disable the entire circuit by inputting low level signal.

The UM154xxS series offer high output voltage accuracy, excellent transient response, stability with ultra low ESR ceramic capacitors as small as 1μF, thermal overload protection and output current limiting. The UM154xxS is available in a low profile SOT23-5 package.

Parameters

- Maximum Input Voltage: 5.5V

- Output Voltage: 1.3V-5V
