NCP571, NCV571  
150 mA CMOS Low Iq Low  
Output Voltage Regulator  
The NCP571 series of fixed output low dropout linear regulators are  
designed for handheld communication equipment and portable battery  
powered applications which require low quiescent current. The  
NCP571 series features an ultralow quiescent current of 4.0 mA.  
Each device contains a voltage reference unit, an error amplifier, a  
PMOS power transistor, resistors for setting output voltage, current  
limit, and temperature limit protection circuits.  
The NCP571 has been designed to be used with low cost ceramic  
capacitors and requires a minimum output capacitor of 0.1 mF. The  
device is housed in the TSOP5 or DFN6 surface mount package.  
Standard voltage versions are 0.8 V, 0.9 V, 1.0 V and 1.2 V.
