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
ADP171 ideal for battery-operated portable equipment.
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

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.
Short-circuit protection and thermal overload protection circuits
are available in tiny 5-lead TSOT for the smallest footprint
solution to meet a variety of portable power applications.
