TPS2145 Datasheet (Texas Instruments)

TPS2145, LDO AND DUAL SWITCH

Two power-distribution switches and an adjustable (TPS2145) or fixed (TPS2147) LDO are incorporated in one small package, providing a power management solution that saves up to 60% in board space over typical implementations.

Designed to meet USB 2.0 bus-powered hub requirements, these devices also
