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.
