The CMPWR161 is a micropower, low noise regulator designed specifically to filter out noise from a 5V digital supply making it ideal for noise-sensitive analog applications. The CMPWR161 delivers up to 150mA at a fixed 4.75V output. A bandgap reference bypass pin (BYP) provides low noise operation when an external capacitor is connected between this pin and ground. In addition, the CMPWR161 features an enable pin (EN) which allows the regulator to be placed into shutdown mode supporting low power and battery applications. The CMOS regulator features low quiescent current even at full load.
