Overview

The ADP7105 is a CMOS, low dropout (LDO) linear regulator that operates 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 1.22 V to 19 V rails. Using an advanced proprietary architecture, the ADP7105 provides high power supply rejection and low noise, and achieves excellent line and load transient response with only a small 1 μF ceramic output capacitor. The ADP7105 is available in three fixed output voltage options and an adjustable version that allows output voltages ranging from 1.22 V to 19 V via an external feedback divider. The ADP7105 allows an external soft start capacitor to be connected to program the startup. The ADP7105 output noise voltage is 15 μV rms and is independent 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 ADP7105 is available in 8 - lead, 3 mm×3 mm LFCSP and 8 - lead SOIC packages. The LFCSP offers a very compact solution and provides excellent thermal performance for applications that require up to 500 mA of output current in a small, low profile footprint.
