NOTES:
5. VOUT = VREF for ADJ version
6. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 100 mV below the value measured
with a 1-V differential. This dropout specification does not apply to the 1.8-V option, as the minimum VIN = 2.2 V must be observed
for proper biasing of LDO control circuitry.
7. The ON/OFF input must be actively terminated. Connect to VIN if this function is not used (see Application Information).
