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× packages.
