Description

Ultra-

The SiS293033 low-noise, low dropout, high precision

linear regulator operates with up to 12V input and

provides 300mA output current. Typical output noise is

44μVRMS with dropout voltage 270mV at 150mA load.

The SiS293033 is highly accurate over temperature

and exhibits excellent load and line transient response.

Ruggedized features include internal output current

limiting; short-circuit protection and thermal overload

protection. Very small die size enables high

integration.
