Industrial and instrumentation

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 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.

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_DOvia an external feedback divider.
