GENERAL DESCRIPTION

The ADP7112 is a CMOS, low dropout (LDO) linear regulator

that operates from 2.7 V to 20 V and provides up to 200 mA of

output current. This high input voltage LDO is ideal for the

regulation of high performance analog and mixed-signal circuits

operating from 19 V down to 1.2 V rails. Using an advanced

proprietary architecture, the device provides high power supply

rejection, low noise, and achieves excellent line and load transient

response with a small 2.2 μF ceramic output capacitor. The

ADP7112 regulator output noise is 11 μV rms, independent of

the output voltage for the fixed options of 5 V or less.

The ADP7112 is available in 15 fixed output voltage options.

The following voltages are available from stock: 1.2 V

(adjustable), 1.8 V, 2.5 V, 3.3 V, and 5.0 V. Additional voltages

available by special order are 1.5 V, 1.85 V, 2.0 V, 2.2 V, 2.75 V,

2.8 V, 2.85 V, 3.8 V, 4.2 V, and 4.6 V.

Each fixed output voltage can be adjusted above the initial set

point with an external feedback divider. This allows the ADP7112

to provide an output voltage from 1.2 V to VIN − VDO with high

PSRR and low noise.

A user-programmable soft start with an external capacitor is

available in the ADP7112. The ADP7112 is available in a 6-ball

1 mm × 1.2 mm WLCSP, making it a very compact solution.
