AMC8878 Datasheet, PDF (4/9 Pages) List of Unclassifed Manufacturers – LOW NOISE 150mA LOW DROPOUT REGULATOR

AMC8878/8879
ELECTRICAL CHARACTERISTICS
Unless otherwise specified, these specifications apply over the operating ambient temperature of 0°C to +70 °C with
V_IN = V_OUT(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 V_OUT inside target value ± 2 %.
3. Regulation is measured at constant junction temperature, using pulsed ON time.
