... Dual Regulator with Independent Output Enables and NOCAPt The CS8371 is an 8.0 V/5.0 V dual output linear regulator. The 8.0 V ±5.0% output sources 1.0 A, while the 5.0 V ±5.0% output sources 250 mA. Each output is controlled by its own ENABLE lead. Setting the ENABLE input high turns on the associated regulator output ...
