LM26003MH/NOPB TI Step-Down Regulator | 20-HTSSOP | 3A, 4.5-38V Input

Product Overview

The LM26003MH/NOPB from Texas Instruments is a high-efficiency, 3A step-down (buck) switching regulator designed for applications requiring a wide input voltage range of 4.5V to 38V. Housed in a compact 20-HTSSOP package, this device integrates a low RDS(on) N-channel MOSFET and features a fixed 500kHz switching frequency. Its current-mode control architecture ensures excellent line and load regulation, while the enable pin and soft-start function provide flexible power sequencing. The LM26003MH/NOPB is ideal for industrial, automotive, and telecom systems where reliability and thermal performance are critical.
