LM3354MMX-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3354MMX-5.0/NOPB is a charge pump switching regulator IC manufactured by Texas Instruments, designed for surface-mount applications in a 10-TFSOP or 10-MSOP package. It provides a fixed positive output voltage of 5V with a maximum output current capability of 90mA. The device operates as a single-output regulator and is classified under the broader category of switching regulators. This component serves as a compact solution for step-up or inversion voltage regulation tasks where space constraints are critical.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated charge pump topology for efficient voltage conversion
• Fixed 5V output configuration simplifies circuit design
• Compact 10-pin MSOP/TFSOP footprint suitable for space-limited boards

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered devices requiring voltage boosting
• LCD bias voltage generation
• General-purpose DC-DC conversion in compact electronics

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific package variant (TFSOP vs MSOP) against your PCB footprint requirements, as both are referenced in distributor listings. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as some sources indicate 'No RoHS Information' while others claim compliance. Ensure the supplier is an authorized channel to guarantee authenticity, given the component's obsolete lifecycle status which may lead to surplus market availability.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output from a lower input voltage is required in a very small form factor. The 90mA current limit makes it suitable for low-power logic or sensor supplies rather than high-current loads. Consider the trade-off between the simplicity of a fixed-output regulator and the efficiency benefits of a charge pump over linear alternatives in low-voltage drop scenarios.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3354 family of charge pump regulators. Unlike the LM335 temperature sensor or LM334 current source found in similar search contexts, the LM3354 is specifically a power management IC. The suffix 'MX' indicates the tape-and-reel packaging format, while 'NOPB' denotes a lead-free and RoHS-compliant version without bromine/antimony additives.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The component lifecycle status is listed as Obsolete. Engineers should consult Texas Instruments for potential newer generations or equivalent charge pump regulators with active production status.
