TC1268数据手册Microchip中文资料规格书

描述 Description

The TC1268 is a fixed output, fast turn-on, high accuracy (typically ±0.5%) CMOS low dropout regulator. Designed specifically for battery-operated systems, the TC1268’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!). TC1268's key features include ultra low noise, very low dropout voltage (typically 350 mV at full load), and fast response to step changes in load. The TC1268 also has a fast wake up response time (5 µsec typically) when released from shutdown. The TC1268 incorporates both over-temperature and over-current protection. The TC1268 is stable with an output capacitor of only 1µF and has a maximum output current of 500 mA.
