TS19603 400mA High Voltage Adjustable Current Regulator With Enable Control SOP-8EP Pin Definition: 1. GND 8. OUT 2. GND 7. OUT 3. VDD 6. NC 4. ISET 5. OE 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. Features Typical Application Circuit 0.28V V 400mA DROP 400mA Maximum Output Current Output Current Controlled by External Resistor 3s Fast Response Output Stage Enable Control Wide Supply Voltage Range: 5~50V TS19603 Applications High Power LED Driver RGB Full Color Power LED Driver LCD Monitor/TV LED Backlight Driver Ordering Information Part No. Package Packing TS19603CS RLG SOP-8EP 2.5Kpcs / 13 Reel Note: G denotes Halogen Free Product.

These are for stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may remain possibility to affect device reliability. Note 3: Thermal Resistance is specified with the component mounted on a low effective thermal conductivity test board in free air at TA=25C. Note 4: 2 square inch of FR-4, double sided, 1 oz. minimum copper weight. Note 5: Devices are ESD sensitive. Handling precaution recommended.
