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.  
IN  
OUT  
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.

BYPASS CAPACITOR (ADP1711)

AND UVLO  
The ADP1711 allows for an external bypass capacitor to be  
connected to the internal reference, which reduces output  
voltage noise and improves power supply rejection. A low  
leakage capacitor of 1 nF or greater (10 nF is recommended)  
must be connected between the BYP and GND pins.

ENABLE FEATURE  
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/ADP1711 use the EN pin to enable and disable  
the OUT pin under normal operating conditions. As shown in  
Figure 19, when a rising voltage on EN crosses the active  
threshold, OUT turns on. When a falling voltage on EN crosses  
the inactive threshold, OUT turns off.  
EN  
The ADP1710 is available in two versions, one with fixed output  
voltage options and one with an adjustable output voltage. The  
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).
