NCP562, NCP563
80 mA CMOS Low Iq
Low−Dropout Voltage
Regulator
This series of fixed output low−dropout linear regulators are
designed for handheld communication equipment and portable battery
powered applications which require low quiescent. This series
http://onsemi.com
features an ultra−low quiescent current of 2.5
Am. 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 NCP562 series provides an
enable pin for ON/OFF control.

The NCP562 has been designed to be used with low cost ceramic
capacitors and requires a minimum output capacitor of 0.1 m F. The
device is 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.
