1. Guaranteed by production test of load regulation and line regulation.

2. Dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT measured for VIN =

(VOUT(NOM) + 500mV). Since the minimum input voltage is 2.0V, this specification is only valid when VOUT(NOM)

> 2.0V.
