ADP1710/ADP1711
THEORY OF OPERATION
The ADP1710/ADP1711 are low dropout, CMOS linear
regulators that use an advanced, proprietary architecture to
provide high power supply rejection ratio (PSRR) and excellent
line and load transient response with just a small 1 μF ceramic
output capacitor. Both devices operate from a 2.5 V to 5.5 V
input rail and provide up to 150 mA of output current.
Incorporating a novel scaling architecture, ground current is
very low when driving light loads. Ground current in shutdown
mode is typically 100 nA.
ADJUSTABLE OUTPUT VOLTAGE
(ADP1710 ADJUSTABLE)
The ADP1710 adjustable version can have its output voltage
set over a 0.8 V to 5.0 V range. The output voltage is set by
connecting a resistive voltage divider from OUT to ADJ. The
output voltage is calculated using the equation
V OUT = 0.8 V (1 + R1 / R2 ) (1)
where:
R1 is the resistor from OUT to ADJ.

R2 is the resistor from ADJ to GND.
The maximum bias current into ADJ is 100 nA, so for less
than 0.5% error due to the bias current, use values less than
60 kΩ for R2.

Figure 18. Internal Block Diagram
Internally, the ADP1710/ADP1711 each consist of a reference,
an error amplifier, a feedback voltage divider, and a PMOS pass
transistor. Output current is delivered via the PMOS pass
device, which is controlled by the error amplifier. The error
amplifier compares the reference voltage with the feedback
voltage from the output and amplifies the difference. If the
feedback voltage is lower than the reference voltage, the gate of
the PMOS device is pulled lower, allowing more current to pass
and increasing the output voltage. If the feedback voltage is
higher than the reference voltage, the gate of the PMOS device
is pulled higher, allowing less current to pass and decreasing the
output voltage.
The ADP1710 is available in two versions, one with fixed output
voltage options and one with an adjustable output voltage. The
must be connected between the BYP and GND pins.
ENABLE FEATURE
The ADP1710/ADP1711 use the EN pin to enable and disable
the OUT pin under normal operating conditions. As shown in
threshold, OUT turns on. When a falling voltage on EN crosses
the inactive threshold, OUT turns off.

fixed output voltage option is set internally to one of sixteen
values between 0.75 V and 3.3 V, using an internal feedback
network. The adjustable output voltage can be set to between 0.8

V and 5.0 V by an external voltage divider connected from OUT
to ADJ. The ADP1711 is available with fixed output voltage
options and features a bypass pin, which allows an external
capacitor to be connected, which reduces internal reference
noise. All devices are controlled by an enable pin (EN).
