Functional Block Diagram Absolute Maximum Ratings
(@TA = +25°C, unless otherwise specified.)
Parameter Rating Unit
Voltage on any pin (relative to IOUT) -0.6 to +20 V Continuous output current, IOUT 25 mA Continuous sense voltage, VSENSE (Note 4) -0.5 to +0.5 V Operating temperature, TA -40 to +85 °C Storage temperature -55 to +125 °C Package power dissipation(@TA = +25°C) SOT25 300 mW Note: 4. Operation above the absolute maximum rating may cause device failure. Operation at absolute maximum ratings, for extended periods, may reduce device reliability
