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.
