UM1330

150mA, Low Noise, Low Dropout Regulator

UM1330S-xx SOT23-5

UM1330P-xx SOT353

UM1330DA-xx DFN6 2.0×2.0

General Description

The UM1330 series are 150mA low dropout regulators design for portable application. A 2.7V to

5.5V input operating voltage range, making them ideal for operation from a single cell lithium ion

battery or fixed 3.3V and 5V systems. With low output noise (56μV_RMS) and high PSRR

(-58dB@1kHz), the UM1330 series are ideal for noise sensitive applications such as RF. While

the fast transient response and active shutdown circuitry make them well-suited for powering

mixed signal circuitry.

Other features include stability with ultra low ESR ceramic capacitors as small as 1μF, thermal

overload protection, output current limiting and auto discharge the output voltage when disabled.

The UM1330 series are available in low profile SOT23-5, SOT353 and DFN6 2.0×2.0 packages.
