TC1187VCT713
低压差稳压器 150mA Adj LDO w/Shdn
50mA, 100mA and 150mA Adjustable CMOS LDOs with Shutdown
General Description TC1187VCT713
The TC1070, TC1071 and TC1187 are adjustable LDOs designed to supersede a variety of older (bipolar) voltage regulators. Total supply current is typically 50μA 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 85mV (TC1070); 180mV (TC1071); and 270mV (TC1187) at full load, and fast response to step changes in load. Supply current is reduced to 0.5μA (max) 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.
