Frequently Asked Questions

What is the input voltage range of the LM2738XMY?

The LM2738XMY accepts an input voltage from 3V to 20V, with a nominal operating voltage of 12V. This wide range makes it compatible with a variety of power sources including single-cell Li-ion batteries, USB, and standard 12V or 15V adapters used in industrial and consumer applications.

What output voltage can the LM2738XMY regulate to?

The output voltage of the LM2738XMY is fully adjustable from 0.8V to 18V using an external resistor divider connected to the feedback pin. This flexibility allows engineers to set precise voltages for microcontrollers, FPGAs, memory, and analog circuits in a single design.

What control method does the LM2738XMY use?

The LM2738XMY uses current-mode pulse width modulation (PWM) control, which provides excellent line and load regulation, fast transient response, and inherent cycle-by-cycle current limiting. This makes it highly suitable for noise-sensitive and efficiency-critical power supply designs.

What package is the LM2738XMY available in?

The LM2738XMY is available in a Small Outline Package (MSOP-8/PDSO-G8), offering a compact PCB footprint ideal for space-constrained applications such as portable devices, wearables, and dense industrial PCB designs.
