1 / 18 page © 2005 Microchip Technology Inc. DS21374C-page 1 TC1263 Features • Very Low Dropout Voltage • 500 mA Output Current • High-Output Voltage Accuracy • Standard or Custom Output Voltages • Overcurrent and Overtemperature Protection • SHDN Input for Active Power Management • ERROR Output Can Be Used as a Low Battery Detector (SOIC only) Applications • Battery-Operated Systems • Portable Computers • Medical Instruments • Instrumentation • Cellular/GSM/PHS Phones • Linear Post-Regulators for SMPS • Pagers Typical Application Description The TC1263 is a fixed-output, high-accuracy (typically ±0.5%) CMOS low dropout regulator. Designed specifically for battery-operated systems, the TC1263’s CMOS construction eliminates wasted ground current, significantly extending battery life. Total supply current is typically 80 µA at full load (20 to 60 times lower than in bipolar regulators). TC1263 key features include ultra low noise operation, very low dropout voltage (typically 350 mV at full load) and fast response to step changes in load. The TC1263 incorporates both overtemperature and overcurrent protection. The TC1263 is stable with an output capacitor of only 1 µF and has a maximum output current of 500 mA. It is available in 8-Pin SOIC, 5-Pin TO-220 and 5-Pin DDPAK packages.
