CM2841GAIM25

CM2841 150mA CMOS LDO WITH EN & PG GENERAL DESCRIPTION The CM2841 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 CM2841 is stable with an output capacitance of 2.2µF or greater. FEATURES Very Low Dropout Voltage Low Current Consumption: Typ. 30µA, Max. 35µA High Accuracy Output Voltage: +/- 1.5% Guaranteed 150mA 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 1M Ω IN PG C M 2841 GND OUT EN OUT 5V C1 1uF C PG * For programming delay C2 4.7uF 2004/05/14 Rev. 1.3 Champion Microelectronic Corporation Page 1 CM2841 150mA CMOS LDO WITH EN & PG PIN CONFIGURATION SOT-23-5 Top View 5 4 OUT GND 2 3 VIN PG EN 1 BLOCK DIAGRAM IN OUT 1uA O vercurrent Shutdown Therm al Shutdown EN R1 PG + AMP + Vref = 1.176V Vref x 85% R2 GND 2004/05/14 Rev. 1.3 Champion Microelectronic Corporation Page 2 CM2841 150mA CMOS LDO WITH EN & PG ORDERING INFORMATION Part Number CM2841ACIM25 CM2841ABIM25 CM2841AIM25 CM2841GACIM25 CM2841GABIM25 CM2841GAIM25 Output Voltage 1.2V 1.3V 1.5V 1.2V 1.3V 1.5V Temperature Range -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ Package SOT-23-5 SOT-23-5 SOT-23-5 SOT-23-5 SOT-23-5 SOT-23-5 Note: For other pre-set output voltage, please contact Champion Sales office.
