These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operation sections of the specifications is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. DC SPECIFICATIONS Electrical Characteristics: V IN = +3.6V, GND = 0V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.

Limits over the operating temperature range are ensured through cor- relation using Statistical Quality Control (SQC) methods. 2: Validated by line regulation test. 3: Not tested. For design purposes, the current limit should be considered 150 mA minimum to 410 mA maximum. 4: The dropout voltage is defined as (V IN – VOUT) when VOUT is 100 mV below the value of VOUT for V IN = VOUT +2V. |
