ABSOLUTE MAXIMUM RATINGS (Operating temperature range applies unless otherwise specified. )
RATINGS UNIT 35 V Input Voltage VIN 40 V Output Current IOUT 0.5 A Power Dissipation PD Internally Limited W Operating Temperature Range TOPR -20 ~ +85 C Operating Junction Temperature TJ 0~+125 C Storage Temperature Range TSTG -40 ~ +150 C Note:1. Absolute maximum ratings are stress ratings only and functional device operation is not implied. The device could be damaged beyond Absolute maximum ratings. 2. The device is guaranteed to meet performance specifications within 0~70 operating temperature range and assured by design from -20~85. 3.The maximum steady state usable output current are dependent on input voltage, heat sinking, lead length of the package and copper pattern of PCB. The data are showed as electrical characteristics table represents pulse test conditions with junction temperatures specified at the initiation of test.
