NCP502/D

NCP502, NCP502A

80 mA CMOS Low Iq, Low−

Dropout Voltage Regulator

The NCP502/A series of fixed output linear regulators are designed

for handheld communication equipment and portable battery powered

applications which require low quiescent. The NCP502/A series

features an ultra−low quiescent current of 40

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 NCP502/A has been designed to be used with low cost ceramic

capacitors. The device is housed in the micro−miniature SC70−5 and

TSOP−5 surface mount packages. Standard voltage versions are 1.5 V,

1.8 V, 2.5 V, 2.7 V, 2.8 V, 2.9 V, 3.0 V, 3.1 V, 3.3 V, 3.4 V, 3.5 V, 3.6 V,

3.7 V and 5.0 V. Other voltages are available in 100 mV steps.
