Limits is 100% production tested at TA= +25°C. Low duty pulse techniques are used during test to maintain

junction temperature as close to ambient as possible.

VIN (min)=VOUT (STD)+VDROPOUT

Not tested. For design purposes, the current limit should be considered 400mA minimum to 600mA maximum.

The dropout voltage is defined as (VIN - VOUT) when VOUT is 100mV below the value of VOUT for VIN = VOUT +1V. The per-

formance of every G914X version, see “Typical Performance Characteristics”.

Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load

regulation in the load range from 1mA to 300mA. Changes in output due to heating effects are covered by the thermal

regulation specification.
