TS2937A Datasheet, PDF (1/6 Pages) Taiwan Semiconductor Company, Ltd – 500mA Ultra Low Dropout Fixed Positive Voltage Regulator

TS2937/A
500mA Ultra Low Dropout Fixed Positive Voltage Regulator
Low Dropout Voltage 0.6V max.
General Description
Pin assignment:
1. Input
2. Ground
3. Output
The TS2937/A 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 500mA). This includes a tight initial tolerance of 1% (TS2937A) and 2% (TS2937),
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.
