GENERAL DESCRIPTION
The ADP1715/16 is a 500mA low-dropout linear regulator
that uses an advanced, proprietary architecture to provide high
power supply rejection ratio (PSRR) and excellent line and
load transient response with just a small 2.2
F ceramic output
capacitor. Supply current in shutdown mode is reduced to less
than 1
A.
Three versions of this part are available: one with fixed output
voltage and variable soft-start, one with fixed output voltage
and output voltage tracking, and one with adjustable output
voltage and fixed soft start. The fixed output voltage is
internally set to one of sixteen values between 0.75V and
3.3V while the adjustable output voltage can be set between
0.8V and 5.0V by an external voltage divider from OUT to
ADJ. The variable soft-start uses an external capacitor at SS
to control the output voltage ramp while the internal soft-start
uses a 3pF capacitor to give a constant 24
s ramp. Tracking
limits the output voltage to the at-or-below voltage at the TRK
pin.
The ADP1715/16 is available in a thermally-enhanced MSOP
package, making it a very compact solution for applications
requiring up to 500mA of output current in a small, low-
profile footprint.
