80 mA CMOS Low Iq NOCAP™ Voltage Regulator

This series of fixed output NOCAP™ linear voltage 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 μA. 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 linear 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.
