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 seriesfeatures an ultra-low quiescent current of 2.5 uA. 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 microF. The device is housed in the micro-miniature SC82-AB surface mountpackage. Standard voltage versions are 1.5, 1.8, 2.5, 2.7, 2.8, 3.0, 3.3,3.5 and 5.0 V. Other voltages are available in 100 mV steps. Pb-free plating options are available.
