The ADP7104 is a CMOS, low dropout 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 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 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 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.
