- Lead-free products 1.5 V to 5.5 V, selectable in 0.1 V steps. ±1.0% 250 m V typ. (3.0 V output product, IOUT = 100 m A) During operation: 35 µA typ., 65 µA max. During shutdown: 0.1 µA typ., 1.0 µA max. 300 m A output is possible (at VIN ≥ VOUT(S) + 1.0 V)- 1 Ensures long battery life. 70 d B typ. (at 1.0 k Hz) Overcurrent of output transistor can be restricted. SOT-89-3, SOT-89-5, 6-Pin HSON(A)
- 1. Attention should be paid to the power dissipation of the package when the output current is large.
