1 / 11 page  CM2843 300mA CMOS LDO WITH EN & PG 2004/06/01 Rev. 1.3 Champion Microelectronic Corporation Page 1 GENERAL DESCRIPTION FEATURES The CM2843 family is positive, linear regulators featured low quiescent current (30µA typ.) with low dropout voltage, making them ideal for battery applications. The space-saving SOT-23-5 package is attractive for “Pocket” and “Hard Held” applications. These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the “Worst” of operating conditions. An additional feature is a “Power Good” detector, which pulls low when the output is out of regulation. The CM2843 is stable with an output capacitance of 2.2µF or greater. Very Low Dropout Voltage Low Current Consumption: Typ. 30µA, Max. 35µA High Accuracy Output Voltage: +/- 2.5% Guaranteed 300mA Output Input Range up to 7.0V Thermal Shutdown Current Limiting Power Good Output Function Compact Package: SOT-23-5 Factory Pre-set Output Voltages Short Circuit Current Fold-Back Low Temperature Coefficient APPLICATIONS Battery-powered devices Personal communication devices Home electric/electronic appliances PC peripherals TYPICAL APPLICATIONS IN OUT C M 2843 PG GND EN IN OU T 5V C1 1uF C2 4.7u F 1M Ω C PG * For programming delay |
