Low Dropout Voltage 0.6V (typ.)
Pin assignment:
1. Input
2. Ground
3. Output
General Description
The TS2940 series of fixed-voltage monolithic micro-power voltage regulators is designed for a wide range of
applications. This device excellent choice of use in battery-power application. Furthermore, the quiescent current
increases on slightly at dropout, which prolongs battery life.
This series of fixed-voltage regulators features very low ground current (100uA Typ.) and very low drop output voltage
(Typ. 60mV at light load and 600mV at 1A). This includes a tight initial tolerance of 1% typ., extremely good line regulation
of 0.05% typ., and very low output temperature coefficient.
This series is offered in 3-pin TO-263, TO-220, TO-252 & SOT-223 package.
Features
— Dropout voltage typically 0.6V @Io=1A
— Output current up to 1A
— Output voltage trimmed before assembly
— -18V Reverse peak voltage
— +30V Input over voltage protection
— +60V Transient peak voltage
— Internal current limit
— Thermal shutdown protection
