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.

performance and occupy minimal board space. Compared with

commodity types of LDOs, the ADP170/ADP171 provide 20 dB

to 40 dB better power supply rejection ratio (PSRR) at 100 kHz,

making the ADP170/ADP171 an ideal power source for analog-

to-digital converter (ADC) mixed-signal processor systems and

allowing use of smaller size bypass capacitors. In addition, low

output noise performance without the need for an additional

bypass capacitor further reduces printed circuit board (PCB)

component count.

The ADP170 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 to 3.0 V via an external

divider. The ADP170/ADP171 are optimized for stable operation

with small 1 μF ceramic output capacitors. Ideal for powering

digital processors, the ADP170/ADP171 exhibit good transient

Short-circuit protection and thermal overload protection circuits

prevent damage in adverse conditions. The ADP170/ADP171

are available in tiny 5-lead TSOT for the smallest footprint

solution to meet a variety of portable power applications.
