Description
General part information
TC1269 Series
The TC1269 is a fixed output, high accuracy (typically ±0.5%) CMOS upgrade for older (bipolar) low dropout regulators. Total supply current is typically 50µA at full load (20 to 60 times lower than in bipolar regulators). TC1269 key features include ultra low noise operation (plus optional Bypass input); very low dropout voltage (typically 240mV at full load), and 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 TC1269 incorporates both over-temperature and over-current protection. The TC1269 is stable with an output capacitor of only 1µF and has a maximum output current of 300mA.
