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 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 ADP7102 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 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.

APPLICATIONS

  • Regulation to noise sensitive applications:
    ADC, DAC circuits, precision amplifiers, high frequency oscillators, clocks, and phase-locked loops
  • Communications and infrastructure
  • Medical and healthcare
  • Industrial and instrumentation

Product Detail

This product has individual evaluations boards at specific voltages or with specific features as well as the RedyKit™. The RedyKit simplifies product evaluation by providing two assembled and tested evaluation boards, plus a full set of product (voltage) options for an IC regulator. All the IC options come sorted and stored in the kit with the Analog Devices part number clearly printed on each antistatic zip-top bag.


Simple device measurements such as line and load regulation, dropout, and ground current can be demonstrated with just a single voltage supply, a voltmeter, a current meter, and load resistors.
