TS19603

400mA High Voltage Adjustable Current Regulator

With Enable Control

1/6

Version: A13

SOP-8EP

General Description

The TS19603 is a high voltage, low dropout current regulator of maximum output current up to 400mA. The output

current is decided by an external resistor, and the output sink current could be disabled via OE pin. TS19603

internally also build-in thermal protection to prevent the chip over heat damage.
