TYPICAL APPLICATION CIRCUITS

GENERAL DESCRIPTION

The ADP7104 is a CMOS, low dropout linear regulator that oper-

ates from 3.3 V to 20 V and provides up to 500 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 ADP7104 is available in seven fixed output voltage options and

an adjustable version, which allows output voltages that range from

1.22 V to VIN − VDO via an external feedback divider.

The ADP7104 output noise voltage is 15 μV rms and is independ-

ent 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 ADP7104 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 500 mA of output current in a small, low profile

footprint.
