ELECTRICAL CHARACTERISTICS
Electrical characteristics are guaranteed over the full operating temperature range of -40°C to +85°C with a
junction temperature from -40°C to +105°C unless otherwise specified. Ambient temperature must be de-rated
based upon power dissipation and package thermal characteristics.
1 Unless otherwise stated, test conditions are
VIN = 3V, FB = OUT, IOUT = 1mA.
