ABSOLUTE MAXIMUM RATINGS

SYMBOLUNITInput Voltage VIN(VIN – VOUT) * IOUT See Figure 1

℃ Junction Temperature TJ℃ Operating Temperature T -20 ~ +85

℃ Storage Temperature TSTG -40 ~ +150 Note 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.

2. The device is guaranteed to meet performance specification within 0℃~+70℃ operating temperature range and assured by design from -20℃~+85℃.
