GENERAL DESCRIPTION

The ADP170/ADP171 are low voltage input, low quiescent current, low-dropout (LDO) linear regulators that operate from 1.6 V to 3.6 V and provide up to 300 mA of output current. The low 66 mV dropout voltage at 300 mA load improves efficiency and allows operation over a wide input voltage range. The low 23 μA of quiescent current at a 0 mA load makes the ADP170/ADP171 ideal for battery-operated portable equipment.
