Note 1: Shutdown current is the input current of VIN & VCNTL drawn by a regulator when the output

voltage is disabled by a shutdown signal on VREF pin (

VIL < 0.2). It is measured with VIN =

1.5V/1.8V/2.5V & VCNTL = 3.3V.

Note 2:

VOS offset is the voltage measurement as VOUT subtracted from VREF.

Note 3: Regulation is measured at constant junction temperature by using a 5ms current pulse.

Devices are tested for load regulation in the load range from 0A to 1.8A peak.
