General Description

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 allow core and I/O voltage sequencing in DSP applications, or power segmentation in portable equipment.

Each currentlimited switch is a 340-mΩ N-channel MOSFET capable of supplying 200 mA of continuous current.

Overview

TPS2145, TPS2147 TPS2155, TPS2157 SLVS333 − AUGUST 2001 LDO AND DUAL SWITCH WITH CONTROLLED RISE TIMES FOR DSP AND PORTABLE.
