LMZ31503RUQR Description

Short technical summary and product information.

The LMZ31503RUQR is a non-isolated point-of-load (PoL) module from Texas Instruments. It delivers up to 3A output current with an adjustable output voltage ranging from 0.8V to 5.5V. The module operates from a minimum input voltage of 4.5V and achieves a typical efficiency of 93.3%. It includes protection features such as overcurrent (OCP), overtemperature (OTP), and undervoltage lockout (UVLO). The enable control is active high. The operating temperature range is -40°C to 85°C, suitable for commercial ITE applications. The module is housed in a 47-BQFN package with an exposed pad and is surface mountable, enabling compact design and efficient thermal management.
