PRODUCTION DATA SHEET

ABSOLUTE MAXIMUM RATINGS

Power Dissipation ................................................................................... Internally Limited

Input Voltage ................................................................................................................ 10V

Input to Output Voltage Differential............................................................................. 10V

Maximum Output Current............................................................................................ 1.5A

Operating Junction Temperature

Plastic (DT, DD, P Packages) ................................................................................ 150°C

Storage Temperature Range....................................................................... -65°C to 150 °C

Peak Package Solder Reflow Temp (40 seconds max. exposure) .................260°C (+0, -5)
