Note 1: All units are 100% tested at T A = +25°C. Limits over the operating temperature range are guaranteed by design.
Note 2: The dropout voltage is defined as V IN - V OUT_ when V OUT_ drops by 100mV from V OUT_ when measured at V IN = +3.7V.
Note 3: Connect P_ to IN or GND through a resistor less than 1k Ω .
