NCP502, NCV502
80 mA CMOS Low Iq,
Low-Dropout Voltage
Regulator
The NCP502 series of fixed output linear regulators are designed for
handheld communication equipment and portable battery powered
applications which require low quiescent. The NCP502 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 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.
