Overview

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.

  • Two 340-mΩ (Typical) High-Side MOSFETs
  • 200 mA Low-Dropout Voltage Regulator In Fixed 3.3-V or Adjustable Versions
  • Independent Thermal- and Short-Circuit Protection for LDO and Each Switch
  • Overcurrent Indicators With Transient Filter
  • 2.9-V to 5.5-V Operating Range
  • CMOS- and TTL-Compatible Enable Inputs
  • 75-µA (Typical) Supply Current
  • Available in 10-Pin MSOP or 14-Pin TSSOP (PowerPAD) D -40°C to 85°C Ambient Temperature Range
