ELECTRICAL CHARACTERISTICS
(VIN = VOUT (NOMINAL) + 0.5V or 2.5V (whichever is greater), TA = - 40°C to +85°C, Typical values are at TA = + 25°C, for each LDO unless
otherwise specified.)

Specifications subject to change without notice.
Note 1: The dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT for VIN = VOUT + 0.5V. (Only applicable for
VOUT = +2.5V to +3.3V)
Note 2: Time needed for VOUT to reach 95% of final value.
