LX8820 TM ® 3.3V/1.0A Ultra Low Dropout Regulator P RODUCTION DATA SHEET DESCRIPTION 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 www.DataSheet4U.com 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 <200µA). compared to BiPolar technology . The low RDSON of the PMOS output stage results in ultra low dropout (typically 0.45V @ 1A).
