CM2862

CM2862 600mA CMOS LDO GENERAL DESCRIPTION The CM2862 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 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 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 M2862 IN IN GND OUT OUT VIN C1 1uF C2 2.2uF 2006/10/11 Rev. 1.1 Champion Microelectronic Corporation Page 1 CM2862 600mA CMOS LDO PIN CONFIGURATION SOT-89 Top View 2862 VOUT GND VIN Pin 1 Pin 2 Pin 3 1 2 3 BLOCK DIAGRAM IN OUT O vercurrent Shutdown Thermal Shutdown R1 + Vref = 1.176V AM P R2 GND ORDERING INFORMATION Part Number CM2862KIM89 CM2862SIM89 Output Voltage 2.5V 3.3V Temperature Range -40℃ ~ +85℃ -40℃ ~ +85℃ Package SOT-89 SOT-89 Note: For other pre-set output voltage, please contact Champion Sales office. 2006/10/11 Rev. 1.1 Champion Microelectronic Corporation Page 2 CM2862 600mA CMOS LDO ABSOLUTE MAXIMUM RATINGS Input Voltage Output Current Output Voltage …………….……………………………. +7V …………………….…………………. 1A …………………… GND-0.3V to VIN+0.3V OPERATING RATINGS Supply Voltage ………………………………. 4.5V to 5.5V Ambient Temperature Range (TA) ……... -40℃ to +85℃ Junction Temperature Range …..…... -40℃ to +125℃ ESD Classification ………………………………………… B THERMAL INFORMATION Parameter Thermal Resistance (Θjc) Thermal Resistance (Θja) Internal Power Dissipation (PD) (ΔT = 100℃, No Heatsink) Maximum Junction Temperature Maximum Lead Temperature (10 Sec) SOT-89 SOT-89 SOT-89 Maximum 100 180 400 150 300 Unit ℃/W ℃/W mW ℃ ℃ ELECTRICAL CHARACTERISTICS TA = +25℃; VIN = VIN(MIN) unless otherwise noted CM2862 Min.
