TPS2157 - LDO AND DUAL SWITCH

Download the TPS2157 datasheet PDF. This datasheet also covers the TPS2145 variant, as both devices belong to the same ldo and dual switch family and are provided as variant models within a single manufacturer datasheet.

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.

Key Features

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