The ADP1762 is a low noise, low dropout (LDO) linear regulator. It is designed to operate from a single input supply with an input voltage as low as 1.10 V, without the requirement of an external bias supply, to increase efficiency and provide up to 2 A of output current.

The low 62 mV typical dropout voltage at a 2 A load allows the ADP1762 to operate with a small headroom while maintaining regulation and providing better efficiency.

The ADP1762 is optimized for stable operation with small 10 μF ceramic output capacitors. The ADP1762 delivers optimal transient performance with minimal board area.

The ADP1762 is available in fixed output voltages ranging from 0.9 V to 1.5 V. The output of the adjustable output model can be set from 0.5 V to 1.5 V through an external resistor connected between VADJ and ground.

The ADP1762 has an externally programmable soft start time by connecting a capacitor to the SS pin. Short-circuit and thermal overload protection circuits prevent damage in adverse conditions. The ADP1762 is available in a small 16-lead LFCSP package for the smallest footprint solution to meet a variety of applications.

APPLICATIONS

  • Regulation to noise sensitive applications such as radio frequency (RF) transceivers, analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuits, phase-locked loops (PLLs), voltage controlled oscillators (VCOs) and clocking integrated circuits
  • Field-programmable gate array (FPGA) and digital signal processor (DSP) supplies
  • Medical and healthcare
  • Industrial and instrumentation

Product Detail

The ADP1761, ADP1762, and ADP1763 evaluation boards demonstrate the functionality of the ADP1761, ADP1762, and ADP1763 series of linear regulators.

Simple device measurements, such as line and load regulation, dropout voltage, and ground current, are demonstrated with only a single voltage supply, a voltmeter, an ammeter, and load resistors.

For full details on the ADP1761, ADP1762, and ADP1763 line regulators, see the ADP1761, ADP1762, and ADP1763 data sheets, which should be consulted in conjunction with the user guide, UG-954, when using this evaluation board.
