UM1330P-xx 150mA，低噪声，低压差线性稳压器
功能特点
低输出噪声线性稳压器
The UM1330P-xx 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 (56μVRMS) and high PSRR (-58dB@1kHz), the UM1330P-xx 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 UM1330P-xx series are available in a low profile SOT353 package.
