NOTES:
1. VIN = VOUT (NOMINAL) + 0.5V or 2.5V, whichever is greater.
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.)
3. VEN = -0.3V to VIN
4. Time needed for VOUT to reach 90% of final value.
