TC1223 Datasheet PDF - Microchip Technology

General Description
The TC1223 and TC1224 are high accuracy (typically ±0.5%) CMOS upgrades for older (bipolar) low dropout
regulators such as the LP2980. Designed specifically for battery-operated systems, the devices’ CMOS construction eliminates wasted ground current, significantly extending battery life. Total supply current is typically 50µA at full load (20 to 60 times lower than in bipolar regulators).

FEATUREs
• Extremely Low Ground Current for Longer Battery Life
• Very Low Dropout Voltage
• Choice of 50mA and 100mA Output (TC1223, TC1224, Respectively)
• High Output Voltage Accuracy
• Standard or Custom Output Voltages
• Power Saving Shutdown Mode
• Over Current and Over Temperature Protection
• Space-Saving 5-Pin SOT-23A Package
• Pin Compatible Upgrades for Bipolar Regulators

APPLICATIONs
• Battery Operated Systems
• Portable Computers
• Medical Instruments
• Instrumentation
• Cellular/GSM/PHS Phones
• Linear Post-Regulators for SMPS
