The ADP170 / ADP171 / ADP172 are low voltage input, low quiescentcurrent, low-dropout (LDO) linear regulators that operate from1.6 V to 3.6 V and provide up to 300 mA of output current. Thelow 55 mV dropout voltage at 300 mA load improves efficiencyand allows operation over a wide input voltage range. The low23 μA of quiescent current at no load makes theADP170 / ADP171 / ADP172 ideal for battery-operated portable equipment.TheADP170 is capable of 31 fixed-output voltage options, ranging from 0.8 V to 3.0 V. ADP171 is an adjustable version, which allows output voltages that range from 0.8 V to3.0 V via an external divider. The ADP170 / ADP171 areoptimized for stable operation with small 1 μF ceramic outputcapacitors. Ideal for powering digital processors, the ADP170 / ADP171 exhibit good transient performance andoccupy minimal board space. Compared with commodity typesof LDOs, the ADP170 / ADP171 provide 20 dB to 40 dB betterpower supply rejection ratio (PSRR) at 100 kHz, making the ADP170 / ADP171 an ideal power source for analog-to-digitalconverter (ADC) mixed-signal processor systems and allowinguse of smaller size bypass capacitors. In addition, low outputnoise performance without the need for an additional bypasscapacitor further reduces printed circuit board (PCB)component count.Short-circuit protection and thermal overload protectioncircuits prevent damage in adverse conditions. TheADP170 / ADP171 are available in tiny 5-lead TSOT for thesmallest footprint solution to meet a variety of portable power
