The LX8820 is an ultra lowdropout single output positivevoltage linear regulator. The regulator has a precise, fixed output capable of delivering 1.2 amps.

The LX8820 output is internally programmed for 3.3V.

Regulator stability is maintained with any capacitor ESR, allowing ceramic, tantalum or electrolytic types. Capacitance range is flexible beginning with 2.2µF to large values.

The CMOS wafer process increasing regulator efficiency by minimizing operating ground current (typically
