CM2860/CM2861 600mA CMOS LDO GENERAL DESCRIPTION The CM2860/2861 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 2.2µF 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: +/- 1.5% Guaranteed 600mA Output Thermal Shutdown Current Limiting Compact Package: SOT-89 and SOT-223 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 C M 2860/ 1 IN IN GN D OUT OU T VI N C1 1uF C2 2. 2 u F 2004/05/12 Rev. 1.5 Champion Microelectronic Corporation Page 1 CM2860/CM2861 600mA CMOS LDO PIN CONFIGURATION SOT-89 Top View SOT-223 Top View Pin 1 Pin 2 Pin 3 2860 GND VIN VOUT Pin 1 Pin 2 Pin 3 2860 VIN GND VOUT 2861 GND VOUT VIN 1 2 3 1 2 3 BLOCK DIAGRAM IN OU T O v e r c u rre n t S hut d o w n Ther m a l S hut d o w n R1 + V r ef = 1 . 176V AM P R2 GN D 2004/05/12 Rev. 1.5 Champion Microelectronic Corporation Page 2 CM2860/CM2861 600mA CMOS LDO ORDERING INFORMATION Part Number CM2860KIM89 CM2860KIM223 CM2860SIM89 CM2860SIM223 CM2861KIM223 CM2861SIM223 CM2860GKIM89 CM2860GKIM223 CM2860GSIM89 CM2860GSIM223 CM2861GKIM223 CM2861GSIM223 Output Voltage 2.5V 2.5V 3.3V 3.3V 2.5V 3.3V 2.5V 2.5V 3.3V 3.3V 2.5V 3.3V Temperature Range -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ Package SOT-89 SOT-223 SOT-89 SOT-223 SOT-223 SOT-223 SOT-89 SOT-223 SOT-89 SOT-223 SOT-223 SOT-223 Note: For other pre-set output voltage, please contact Champion Sales office.
