描述
The RAA214223 is a low-dropout linear voltage regulator that operates with a wide input voltage range from 4V to 20V, and the device provides up to 150mA of output current at a fixed output voltage of 3.3V.
Featuring a wide input voltage range with excellent line and load regulation, the device also has integrated fault protection that includes over-temperature shutdown (OTSD) and short-circuit current limit.
The output voltage of the device is fixed at 3.3V, and the device does well with regulating both the over-temperature and the operating range of the input voltage and load. It is also stable with a multilayer ceramic capacitor (MLCC) output capacitor as low as 1μF.
The RAA214223 is available in the 5-pin TSOT23 package.
