MICROCHIP TC1070/TC1071/TC1187 handbook

The TC1070, TC1071 and TC1187 are adjustable LDOs designed to supersede a variety of older (bipolar) voltage regulators. Total supply current is typically 50 μA at full load (20 to 60 times lower than in bipolar regulators). The devices’ key features include ultra low-noise operation, very low dropout voltage – typically 85 mV (TC1070); 180 mV (TC1071); and 270 mV (TC1187) at full load, and fast response to step changes in load. Supply current is reduced to 0.5 μA (maximum) when the shutdown input is low. The devices incorporate both over-temperature and over-current protection. Output voltage is programmed with a simple resistor divider from VOUT to ADJ to GND. The TC1070, TC1071 and TC1187 are stable with an output capacitor of only 1 μF and have a maximum output current of 50 mA, 100 mA and 150 mA, respectively. For higher output versions, please see the TC1174 (IOUT).
