UM37531S - VLDO Linear Regulator

Download the UM37531S datasheet PDF. This datasheet also covers the UM37512S variant, as both devices belong to the same vldo linear regulator family and are provided as variant models within a single manufacturer datasheet.

Description

The UM375xx series are VLDO (very low dropout) linear regulators designed for low power portable applications.

Features

  • include high output voltage accuracy, under voltage lockout, stability with ultra low ESR ceramic capacitors as small as 1μF, thermal overload protection and output current limiting. The UM375xx series are available in a low profile SOT23-5 and SOT353 package.

UM375xx 300mA, Micropower, VLDO Linear Regulator UM375xxS SOT23-5 UM375xxP SOT353 General Description The UM375xx series are VLDO (very low dropout) linear regulators designed for low power portable applications. Typical output noise is only 170μVRMS (UM37512) and maximum dropout is just 200mV at the load current of 100mA.The internal P-channel MOSFET pass transistor requires no base current, allowing the device to draw only 90μA during normal operation at the maximum load current of 300mA. Other features include high output voltage accuracy, under voltage lockout, stability with ultra low ESR ceramic capacitors as small as 1μF, thermal overload protection and output current limiting. The UM375xx series are available in a low profile SOT23-5 and SOT353 package.
