80 mA CMOS Low Iq

NOCAPE Voltage Regulator

This series of fixed output NOCAP linear regulators are designed

for handheld communication equipment and portable battery powered

applications which require low quiescent. This series features an

ultra−low quiescent current of 2.8

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 NCP552 series provides an enable pin for

ON/OFF control.

These voltage regulators have been designed to be used with low

cost ceramic capacitors. The devices have the ability to operate

without an output capacitor. The devices are housed in the

micro−miniature SC82−AB surface mount package. Standard voltage

versions are 1.5, 1.8, 2.5, 2.7, 2.8, 3.0, 3.3, and 5.0 V. Other voltages

are available in 100 mV steps.
