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
V_IN = 3V, FB = OUT, I_OUT = 1mA.

(1) These are stress ratings only and functional operation is not implied. Exposure to absolute maximum ratings for prolongued time periods
may affect device reliability. All voltages are with respect to ground.
