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.

Accuracy when OUT is connected directly to ADJ. When OUT voltage is set by external feedback resistors, absolute accuracy in adjust mode depends on the tolerances
of resistors used.
2
Based on an end-point calculation using 10 mA and 300 mA loads. See Figure 10 for typical load regulation performance for loads less than 10 mA.
3
Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage. This applies only for output
voltages above 2.5 V.
4
Start-up time is defined as the time between the rising edge of EN to OUT being at 95% of its nominal value.
5
Current limit threshold is defined as the current at which the output voltage drops to 90% of the specified typical value. For example, the current limit for a 1.0 V
output voltage is defined as the current that causes the output voltage to drop to 90% of 1.0 V, or 0.9 V.
