LM3103MH/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3103MH/NOPB is a synchronous step-down voltage regulator from Texas Instruments, operating at a fixed switching frequency of 1 MHz. It delivers an output current of 0.75 A with an adjustable output voltage range starting from 800 mV up to 7 V. The device accepts an input voltage between 4.5 V and 42 V. It utilizes a constant on-time control architecture that eliminates the need for external loop compensation. The component is housed in a thermally enhanced HTSSOP-16 package and supports operation across an extended temperature range from -40°C to +125°C.
