CM2836B

CM2836/B/C 300mA LOW ESR CMOS LDO WITH ENABLE GENERAL DESCRIPTION The CM2836/B/C 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, making them ideal for battery applications. EN input connected to CMOS has low bias current. The space-saving SC70 package is attractive for “Pocket” and “Hand Held” applications. These rugged devices have both Thermal Shutdown, and Current limit to prevent device failure under the “Worst” of operating conditions. In application requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass and Ground. The CM2836/B/C is stable with a Low ESR output capacitance of 1.0µF or greater. FEATURES Very Low Dropout Voltage Low Current Consumption: Typ. 30µA, Max. 35µA More Options Output Voltage High Accuracy Output Voltage: +/- 2% Guaranteed 300mA Output Input Range up to 7.0V Thermal Shutdown Current Limiting Stability with Low ESR Capacitors Compact Package: SOT-23 / SOT-89 / SC70 Factory Pre-set Output Voltages Low Temperature Coefficient APPLICATIONS Battery-powered devices Personal communication devices Home electric/electronic appliances PC peripherals TYPICAL APPLICATIONS 2007/06/28 Rev1.1 Champion Microelectronic Corporation Page 1 CM2836/B/C 300mA LOW ESR CMOS LDO WITH ENABLE PIN CONFIGURATION SOT-23-3 Top View 3 SOT-23-5 Top View Pin 1 Pin 2 Pin 3 1 2 2836 GND VOUT VIN 2836B VIN VOUT GND Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 2836 VIN GND EN BYP VOUT SC70-5 Top View SOT-89 Top View Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 CM2836 VIN GND EN BYP VOUT 2836B NC GND NC VIN VOUT 2836C NC VIN NC GND VOUT Pin 1 Pin 2 Pin 3 1 2 3 2836 GND VIN VOUT BLOCK DIAGRAM IN OUT 1uA O v e rc u rre n t S h u td o w n T h e rm a l S h u td o w n EN R1 BYP + Vref = 1.176V AMP R2 GND 2007/06/28 Rev1.1 Champion Microelectronic Corporation Page 2 CM2836/B/C 300mA LOW ESR CMOS LDO WITH ENABLE ORDERING INFORMATION Example: Part Number CM2836/B/CGSIM23 CM2836/B/CGSIM25 CM2836/B/CGSIM89 CM2836/B/CGSIM75 Output Voltage 3.3V 3.3V 3.3V 3.3V Temperature Range -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ Package SOT-23 SOT-23-5 SOT-89 SC70-5 Note: For other pre-set output voltage requirements, please contact Champion Sales office.
