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 100μV

RMS

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.

Applications

Bluetooth/802.11 Cards

PDAs and Notebook Computers

Portable Instruments and

Battery-Powered Systems

Cellular Phones
