AS1370 − Electrical Characteristics

Note(s):

1. Dropout voltage = VIN - VOUT when VOUT is 100mV < VOUT for VIN = VOUT(NOMINAL) +1V (applies only to output voltages ≥ 2.6V).

2. VOUT(NOMINAL) ≥ 1.6V.

3. The rise and fall time of the shutdown signal must not exceed 100ns.

4. The delay time is defined as time required to set VOUT to 95% of its final nominal value.
