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

Figure 3. ADP1716 with Output Voltage Tracking
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.
