CM2835DIM23

CM2835 300mA CMOS LDO GENERAL DESCRIPTION The CM2835 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 and SOT-89 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. The CM2835 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, 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, SOT-89 Factory Pre-set Output Voltages Low Temperature Coefficient APPLICATIONS Battery-powered devices Personal communication devices Home electric/electronic appliances PC peripherals TYPICAL APPLICATIONS C M2835 IN IN GND OUT OUT 5V C1 1uF C2 1.0uF 2006/01/23 Rev1.2 Champion Microelectronic Corporation Page 1 CM2835 300mA CMOS LDO PIN CONFIGURATION SOT-23 Top View SOT-89 Top View 3 VIN VOUT 1 2 2 OUT GND BLOCK DIAGRAM IN O vercurrent Shutdown Thermal Shutdown + Vref = 1.176V AMP 2006/01/23 Rev1.2 Champion Microelectronic Corporation 1 R1 R2 3 VOUT GND GND VIN Page 2 CM2835 300mA CMOS LDO ORDERING INFORMATION Part Number CM2835DIM23 CM2835DIM89 CM2835KIM23 CM2835KIM89 CM2835PIM23 CM2835PIM89 CM2835SIM23 CM2835SIM89 CM2835GDIM23 CM2835GDIM89 CM2835GKIM23 CM2835GKIM89 CM2835GNIM23 CM2835GNIM89 CM2835GPIM23 CM2835GPIM89 CM2835GSIM23 CM2835GSIM89 Output Voltage 1.8V 1.8V 2.5V 2.5V 3.0V 3.0V 3.3V 3.3V 1.8V 1.8V 2.5V 2.5V 2.8V 2.8V 3.0V 3.0V 3.3V 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℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ -40℃ ~ +85℃ Package SOT-23 SOT-89 SOT-23 SOT-89 SOT-23 SOT-89 SOT-23 SOT-89 SOT-23 SOT-89 SOT-23 SOT-89 SOT-23 SOT-89 SOT-23 SOT-89 SOT-23 SOT-89 Note: For other pre-set output voltage requirements, please contact Champion Sales office.
