Note 1: Production tested at TA = +25°C. Overtemperature limits are guaranteed by ATE characterization between -40°C ≤ TJ ≤ +150°C, unless otherwise noted. Thermally limited, not all combinations of input voltage and current are tested.
Note 2: Observe the absolute maximum power dissipation limits.
Note 3: Specification characterized up to +150°C operating junction temperature. Limits are guaranteed by bench characterization.
Note 4: Dropout voltage is defined as (VIN - VOUT) when VOUT is 2% below the value of VOUT for VIN = VOUT + 3V.
Note 5: Not production tested.
Note 6: ENABLE is internally pulled to GND.
Note 7: The device is designed for continuous operation up to TJ = +125°C for 95,000 hours and TJ = +150°C for 5,000 hours.
