Applications
The LM3354MMX-3.7 is ideal for portable electronics, wearables, and handheld instruments that require a stable 3.7 V rail derived from a single Li-Ion or Li-Polymer cell without inductors. Its switched-capacitor design is especially well-suited for RF front-end and audio circuit power supplies where inductor-generated switching noise is unacceptable. It is also used in medical devices and low-EMI sensor nodes requiring clean, regulated voltage from coin-cell or thin-battery sources.

Frequently Asked Questions
What output voltage does the LM3354MMX-3.7 regulate to, and what input voltage range is required?
The LM3354MMX-3.7 provides a fixed 3.7 V regulated output, designed to operate from input voltages typically in the 4.0 V to 6.0 V range sourced from a single Li-Ion battery or a 4-cell alkaline stack. The fixed output eliminates the need for external feedback resistors, simplifying bill-of-materials and PCB layout in portable product designs.
Does the LM3354MMX-3.7 require an inductor, and how does that affect PCB layout complexity?
No, the LM3354MMX-3.7 is an inductorless switched-capacitor regulator that requires only small external flying and reservoir capacitors, typically 1 µF to 4.7 µF ceramic capacitors. Eliminating the inductor reduces PCB area by approximately 30% to 50% compared to a boost or buck converter and removes the main source of EMI in noise-sensitive RF and analog circuit designs.
What load current can the LM3354MMX-3.7 supply, and what efficiency does it achieve at typical loads?
The LM3354MMX-3.7 delivers up to 80 mA of continuous output current at 3.7 V, achieving conversion efficiency above 90% at light loads below 20 mA typical of IoT sensor nodes and Bluetooth modules. Efficiency is maintained across the load range by internal oscillator frequency adjustment, minimizing quiescent current draw from the battery in sleep modes.
In what package is the LM3354MMX-3.7 available, and how does package size compare to alternative LDO regulators at the same output?
The LM3354MMX-3.7 is supplied in a 5-pin SOT-23 package measuring approximately 2.9 mm x 1.6 mm, comparable in footprint to a standard LDO in SOT-23 but without the thermal dissipation constraints of a linear regulator. Unlike an LDO dropping 1 V at 80 mA (losing 80 mW as heat), the switched-capacitor topology operates near 90% efficiency, making it cooler in the same compact package.
