Note:
1. C_IN: A 1.0 µF capacitor (or larger) should be placed between V_IN to GND.
2. C_OUT: A 1.0 µF (or larger) capacitor is recommended between V_OUT and GND for stability. The part may oscillate without the capacitor. Any
type of capacitor can be used, but not Aluminum electrolytics when operating below -25 ^OC, The capacitance may be increased without limit.
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.
