NOCAP� 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 �A. 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.
