1.2 V to 3.5 V, selectable in 0.05 V step
1.7 V to 5.5 V
±1.0% (1.2 V to 1.45 V output product : ±15 m V) 210 m V typ. (2.8 V output product, IOUT = 300 m A) During operation: 45 μA typ., 65 μA max. During power-off: 0.1 μA typ., 1.0 μA max. Possible to output 300 m A (VIN ≥ VOUT(S) + 1.0 V)- 1 A ceramic capacitor of 1.0 μF or more can be used. 70 d B typ. (f = 1.0 k Hz)
Soft-start time : 0.7 ms typ. (CSS = 1.0 n F) Limits overcurrent of output transistor.
Ensures long battery life.
Discharge shunt function “available” / “unavailable” is selectable.
Pull-down function “available” / “unavailable” is selectable.
