The ADPL40505A is a 5.5V, P-Channel Metal-Oxide Semiconductor (PMOS) Low Drop-Out (LDO) linear regulator that delivers up to 500mA load current. The ADPL40505A features a low-power mode of operation that consumes very low quiescent current from the supply.

The regulator is fully protected from damage by internal circuitry that provides programmable inrush current limiting, output overcurrent limiting, reverse current limiting, and thermal overload protection. The ADPL40505A has an 800Ω active discharge feature to quickly discharge output capacitors.

The ADPL40505A provides enhanced flexibility with an adjustable output voltage in the range of 0.8V to 5.0V by using two external feedback resistors.

The ADPL40505A is available in an 8-pin, 2mm x 2mm Thin Dual Flat No-Lead (TDFN) package.
