LM2936MMX-3.3 Equivalent & Substitute Parts Reference

Part Overview

The LM2936MMX-3.3 by Texas Instruments is a linear voltage regulator IC providing a positive fixed 3.3V output at up to 50mA in an 8-VSSOP surface mount package. This device is classified under Power Management (PMIC) components and features over temperature, reverse polarity, and short circuit protection. Currently, the LM2936MMX-3.3 is listed as obsolete, necessitating the use of alternative models with identical electrical and mechanical parameters for new designs, ongoing manufacturing, or replacement maintenance.
