GENERAL DESCRIPTION
The ADP7102 is a CMOS, low dropout linear regulator that
operates from 3.3 V to 20 V and provides up to 300 mA of
output current. This high input voltage LDO is ideal for
regulation of high performance analog and mixed signal
circuits operating from 19 V to 1.22 V rails. Using an
advanced proprietary architecture, it provides high power
supply rejection, low noise, and achieves excellent line and
load transient response with just a small 1 μF ceramic
output capacitor.
The ADP7102 is available in 7 fixed output voltage options and
an adjustable version, which allows output voltages that range
from 1.22 V to V IN ? V DO via an external feedback divider.

Figure 2. ADP7102 with Adjustable Output Voltage, 5 V
The ADP7102 output noise voltage is 15 μV rms and is inde-
pendent of the output voltage. A digital power good output
allows power system monitors to check the health of the output
voltage. A user programmable precision undervoltage lockout
function facilitates sequencing of multiple power supplies.
The ADP7102 is available in 8-lead, 3 mm × 3 mm LFCSP
and 8-lead SOIC packages. The LFCSP offers a very compact
solution and also provides excellent thermal performance for
applications requiring up to 300 mA of output current in a
small, low-profile footprint.
