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 powerapplications.
ApplicationsAt least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
