Figure 3. ADP1716 with Output Voltage Tracking
GENERAL DESCRIPTION
The ADP1715/ADP1716 are low dropout, CMOS linear
regulators that operate from 2.5 V to 5.5 V and provide up to
500 mA of output current. Using an advanced proprietary
architecture, they provide high power supply rejection and
achieve excellent line and load transient response with just a
small 2.2 μF ceramic output capacitor.
Three versions of this part are available, one with fixed
output voltage options and variable soft start (ADP1715),
one with adjustable output voltage and fixed soft start
(ADP1715 Adjustable), and one with voltage tracking in
fixed output voltage options (ADP1716). The fixed output
voltage options are internally set to one of sixteen values
between 0.75 V and 3.3 V; the adjustable output voltage can
be set to any value between 0.8 V and 5.0 V by an external
voltage divider connected from OUT to ADJ. The variable
soft start uses an external capacitor at SS to control the
output voltage ramp. Tracking limits the output voltage to
the at-or-below voltage at the TRK pin.
The ADP1715/ADP1716 are available in 8-lead thermally
enhanced MSOP packages, making them not only a very
compact solution but also providing excellent thermal
performance for applications requiring up to 500 mA of output
current in a small, low profile footprint.

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 500 mA loads. See Figure 8 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.

Description
Enable Input. Drive EN high to turn on the regulator; drive it low to turn off the
regulator. For automatic startup, connect EN to IN.
Regulator Input Supply. Bypass IN to GND with a 2.2 μF or greater capacitor.
Regulated Output Voltage. Bypass OUT to GND with a 2.2 μF or greater
capacitor.
Soft Start. A capacitor connected to this pin determines the soft-start time.
Adjust. A resistor divider from OUT to ADJ sets the output voltage.
Track. The output will follow the voltage placed on the TRK pin. (See the
Theory of Operation section for a more detailed description.)
