ELECTRICAL CHARACTERISTICS
Unless otherwise specified, these specifications apply over the operating ambient temperature of 0°C to +70°C with
VIN = VOUT(NOMIAL) + 0.5V, and are for DC characteristics only. (Low duty cycle pulse testing techniques are used
which maintains junction and case temperatures equal to the ambient temperature.)

Note:
1. Current limit is measured at constant junction temperature, using pulse ON time.
2. Dropout is measured at constant junction temperature, using pulse ON time, and criterion is VOUT inside target value ± 2 %.
3. Regulation is measured at constant junction temperature, using pulsed ON time.
