MP8801 – LOW DROPOUT, 150mA LINEAR REGULATOR  
PIN FUNCTIONS  
Pin #  
Name Description  
Power Source Input. IN supplies the internal power to the MP8801 and is the source of the  
pass transistor. Bypass IN to GND with a 1μF or greater capacitor.  
Ground.  
Enable Input. Drive EN high to turn on the MP8801; low to turn it off. For automatic startup,  
connect EN to IN.

Feedback Input. Connect a resistive voltage divider from OUT to FB to set the output  
voltage. The OUT feedback threshold is 1.222V.  
Regulator Output. OUT is the output of the linear regulator. Bypass OUT to GND with a

1μF or greater capacitor.  
OPERATION  
The MP8801 is a low-current, low-noise,  
high-PSRR, low-dropout linear regulator. It is  
intended for use in devices that require very low  
noise power supplies and high-PSRR such as  
PLL VCO supplies for mobile handsets and  
802.11 PC Cards, as well as audio codecs and  
microphones. The MP8801 uses a PMOS pass  
element and features internal thermal shutdown.  
The normally fixed output MP8801 may be  
converted to an adjustable output device by  
applying a resistor divider network as shown in  
Figure 2. An optional feed-forward capacitor, CBYP  
,
may be added for an improved transient response.
