GENERAL DESCRIPTION
The ADP1710/ADP1711 are low dropout linear regulators
that operate from 2.5 V to 5.5 V and provide up to 150 mA of
output current. Utilizing a novel scaling architecture, ground
current drawn is a very low 40 μA, when driving a 100 μA
load, making the ADP1710/ADP1711 ideal for battery-
operated portable equipment.
The ADP1710 and the ADP1711 are each available in sixteen
fixed output voltage options. The ADP1710 is also available in
an adjustable version, which allows output voltages that range
from 0.8 V to 5 V via an external divider. The ADP1711 allows
for a reference bypass capacitor to be connected, which reduces
output voltage noise and improves power supply rejection.

The ADP1710/ADP1711 are optimized for stable operation with
small 1 μF ceramic output capacitors, allowing for good transient
performance while occupying minimal board space. An enable
pin controls the output voltage on both devices. There is also an
under-voltage lockout circuit on both devices, which disables the
regulator if IN drops below a minimum threshold.
An internal soft start gives a typical start-up time of 80 μs.
Short-circuit protection and thermal overload protection
circuits prevent damage to the devices in adverse conditions.
Both the ADP1710 and the ADP1711 are available in tiny
5lead TSOT packages, for the smallest footprint solution to all
your power needs.
