The TC1174VOA is an adjustable output CMOS low dropout regulator. Total supply current is typically 50µA at full load (20 to 60 times lower than in bipolar regulators). TC1174VOA key features include ultra low noise operation (plus optional Bypass input); very low dropout voltage (typically 240mV at full load) and internal feed-forward compensation for fast response to step changes in load. Supply current is reduced to 0.05µA (typical) and VOUT falls to zero when the shutdown input is low. The TC1174VOA incorporates both over-temperature and over-current protection. The TC1174VOA is stable with an output capacitor of only 1µF and has a maximum output current of 300mA.
