Overview
Description
The RAA214220 is a low dropout linear voltage regulator that operates with a very wide input voltage range. It provides up to 150mA of output current. The device features a wide input voltage range (2.5V–20V) with excellent line and load regulation. It has integrated fault protection such as over temperature shut down (OTSD) and short-circuit current limit. It is suited for battery powered and USB devices. The output voltage of the device is adjustable with an external resistor network between the output pin and ground. It is well regulated over temperature and the operating range of the input voltage and load. The device is stable with an MLCC output capacitor as low as 1µF. The RAA214220 is available in the 5-pin TSOT23 package.
