GENERAL DESCRIPTION
The ADP1712/ADP1713/ADP1714, available in a tiny, 5-lead
TSOT package, are low dropout linear regulators that operate
from 2.5 V to 5.5 V and provide up to 300 mA of output current.
The low 170 mV dropout voltage at a 300 mA load improves
efficiency and allows operation over a wide input voltage range.
Using a novel scaling architecture, ground current is a very low
75 μA when driving a 100 μA load, making the ADP1712/
ADP1713/ADP1714 ideal for battery-operated portable equipment.
The ADP1712/ADP1713/ADP1714 are available in 16 fixed
output voltage options. The ADP1712 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 ADP1712 fixed version
allows an external capacitor to be connected to program the
soft-start time. The ADP1713 allows a reference bypass capacitor
to be connected, which reduces output voltage noise and
improves power supply rejection. The ADP1714 includes a
tracking feature, which allows the output to follow an external
voltage rail or reference.
The ADP1712/ADP1713/ADP1714 are optimized for stable
operation with small 2.2 μF ceramic output capacitors, allowing
good transient performance while occupying minimal board
space. An enable pin controls the output voltage on all devices,
and an undervoltage lockout circuit disables the regulator if IN
drops below a minimum threshold. The parts also have short
circuit protection and thermal overload protection, which
prevent damage to the devices in adverse conditions.
