Specifications subject to change without notice.
Note 1: VIN = VOUT(NOMINAL) + 0.5V or 2.5V, whichever is greater.
Note 2: 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 +5.0V.)
Note 3: Time needed for VOUT to reach 95% of final value.
