CMPWR161  
Micropower, Low Noise 4.75V/150mA LDO Regulator  
Features  
Product Description  
Excellent power supply ripple rejection for  
VIN-VOUT down to 110mV  
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 appli-  
cations. 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.  
Excellent power supply ripple rejection in  
audible band (20Hz to 20KHz)  
Very low dropout voltage (110mV at 150mA)  
Fast transient response minimizes glitches in  
audible band.  
Low noise in audible band  
Guaranteed to deliver 150mA output at  
4.75V output  
Low quiescent current—300µA typical  
"Zero" current shutdown mode  
5205 compatible pin-out  
5-lead SOT-23 package  
Lead-free version available  
The CMPWR161 is housed in a 5-pin SOT-23 package,  
which is ideal for space critical applications. It is avail-  
able with optional lead-free finishing.  
Applications  
5V analog supply for audio CODEC
