ADP1762WACPZ-R7

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.

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
