CM2838 300mA LOW ESR CMOS LDO WITH ENABLE GENERAL DESCRIPTION The CM2838 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 SOT-23-5 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 CM2838 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 Output Voltage: 1.8V, 2.5V, 2.8V, 3.0V, and 3.3V High Accuracy Output Voltage: +/- 1.5% Guaranteed 300mA Output Input Range up to 7.0V Thermal Shutdown Current Limiting Stability with Low ESR Capacitors Compact Package: SOT-23-5 Factory Pre-set Output Voltages Low Temperature Coefficient APPLICATIONS Battery-powered devices Personal communication devices Home electric/electronic appliances PC peripherals TYPICAL APPLICATIONS IN IN CM2838 BYP GND OUT EN OUT 5V C1 1uF C2 1nF C3 1.0uF 2006/10/11 Rev. 1.3 Champion Microelectronic Corporation Page 1 CM2838 300mA LOW ESR CMOS LDO WITH ENABLE PIN CONFIGURATION SOT-23-5 Top View 5 4 VOUT GND 2 VIN 1 BLOCK DIAGRAM IN EN 3 BYP OUT 1uA O vercurrent Shutdown Thermal Shutdown EN BYP R1 + Vref = 1.176V AMP R2 GND 2006/10/11 Rev. 1.3 Champion Microelectronic Corporation Page 2 CM2838 300mA LOW ESR CMOS LDO WITH ENABLE ORDERING INFORMATION Part Number CM2838DIM25 CM2838KIM25 CM2838NIM25 CM2838PIM25 CM2838SIM25 CM2838GDIM25 CM2838GKIM25 CM2838GNIM25 CM2838GPIM25 CM2838GSIM25 Output Voltage 1.8V 2.5V 2.8V 3.0V 3.3V 1.8V 2.5V 2.8V 3.0V 3.3V Temperature Range -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -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 SOT-23-5 SOT-23-5 SOT-23-5 SOT-23-5 Note: For other pre-set output voltage requirements, please contact Champion Sales office.
