These LDOs offer extremely low quiescent Digital Cameras current which only increases slightly under load, thus providing advantages in ground FEATURES current performance over bipolar LDOs. The LDOs handle an extremely wide load range 100mA/200mA Output Current and guarantee stability with a 1F ceramic SP6200: 100mA SP6201: 200mA output capacitor. They have excellent low Low Dropout Voltage: 160mV 100mA frequency Power Supply Rejection Ratio (PSRR), not found in other CMOS LDOs and 2.5V to 6.0V Input Voltage thus offer exceptional Line Regulation. High Fixed and Adjustable Output Voltage frequency PSRR is better than 40dB up to 2% Output Voltage Accuracy 400kHz. Load Regulation is excellent and temperature stability is comparable to bipolar Ultra Low Ground Current: LDOs. An enable feature is provided on all 200A 200mA & 28A 100A Load versions. Tight Load and Line Regulation Both LDOs are available in fixed & adjustable 78dB PSRR 1KHz output voltage versions and come in an industry standard 5-pin SOT-23 and small RESET/Power Good Output 2X3mm 8-pin DFN packages. A V good OUT Logic-Controlled Electronic Enable indicator is provided on all fixed output versions.
