NCP551, NCV551  
150 mA CMOS Low Iq  
Low−Dropout Voltage  
Regulator  
The NCP551 series of fixed output low dropout linear regulators are  
designed for handheld communication equipment and portable battery  
powered applications which require low quiescent. The NCP551  
series features an ultra−low 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 NCP551 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 micro−miniature TSOP−5 surface mount  
package. Standard voltage versions are 1.5, 1.8, 2.5, 2.7, 2.8, 3.0, 3.2,  
3.3, and 5.0 V. Other voltages are available in 100 mV steps.
