LDO Regulator, 80 mA, Ultra-Low Iq

This fixed output low dropout (LDO) linear voltage regulator is designed for handheld communication equipment and portable battery powered applications which require low quiescent. This series features an ultra-low quiescent current of 2.5 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 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 mount package. 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.
