CM2865E5

CM2865(A)E5 350mA CMOS LDO HIGH ACCURACY VOUT 1.0% GENERAL DESCRIPTION The CM2865/A family is a positive voltage linear regulator developed utilizing CMOS technology featured low quiescent current (30μA typ.), low dropout voltage, and high output voltage accuracy. Built-in low on-resistance transistor provides low dropout voltage and large output current. A 1.0μF or greater can be used as an output capacitor. The SOT-89 and SOT-223 packages are attractive for “Pocket” and “Hand Held” applications. These robust devices are designed to prevent device failure under the worst operation condition with both Thermal Shutdown and Current Fold-back. FEATURES Very Low Dropout Voltage Low Current Consumption: Typ. 30μA, Max. 35μA High Accuracy Output Voltage: +/- 1.0% Guaranteed 350mA Output Thermal Shutdown Current Limiting Reverse battery protection Compact Package: SOT-89 and SOT-223 Factory Pre-set Output Voltages Low Temperature Coefficient APPLICATIONS Battery-powered devices Personal communication devices Home electric/electronic appliances PC peripherals TYPICAL APPLICATIONS 2006/08/03 Rev. 1.0 Champion Microelectronic Corporation Page 1 CM2865(A)E5 350mA CMOS LDO HIGH ACCURACY VOUT 1.0% PIN CONFIGURATION SOT-89 Top View SOT-223 Top View Pin 1 Pin 2 Pin 3 2865 GND VIN VOUT Pin 1 Pin 2 Pin 3 2865 2865A VIN GND GND VOUT VOUT VIN 1 2 3 1 2 3 BLOCK DIAGRAM +/-1% 2006/08/03 Rev. 1.0 Champion Microelectronic Corporation Page 2 CM2865(A)E5 350mA CMOS LDO HIGH ACCURACY VOUT 1.0% ORDERING INFORMATION Part Number CM2865E5IM89 CM2865GE5IM89 CM2865E5IM223 CM2865GE5IM223 CM2865AE5IM223 CM2865AGE5IM223 Output Voltage 1.95V 1.95V 1.95V 1.95V 1.95V 1.95V Temperature Range -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ Package SOT-89 SOT-89 SOT-223 SOT-223 SOT-223 SOT-223 Note: For other pre-set output voltage, please contact Champion Sales office.
