LM2830ZQMFX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2830ZQMFX/NOPB is a high-efficiency step-down switching regulator from Texas Instruments, designed for battery-powered applications. It operates with an input voltage range of 2.7V to 5.5V and delivers a fixed output voltage of 1.2V at up to 1A load current. The device integrates a 1.2MHz switching frequency to allow the use of small inductors and capacitors. Key electrical parameters include a quiescent current of 140µA and a shutdown current of less than 1µA. It features thermal shutdown and current limit protection within a 6-pin SOT-23 package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free status and RoHS compliance. Confirm the ZQM package code matches the required SOT-23 footprint. Ensure the FX tape-and-reel quantity aligns with production needs. Cross-reference the manufacturer's latest datasheet for any pinout or electrical specification updates prior to finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.2V output is required from a single-cell lithium-ion or alkaline battery source. The fixed frequency operation simplifies filter design compared to variable frequency regulators. Consider the 1A current capability against peak load requirements. Evaluate the thermal performance in the intended enclosure space given the small package size.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2830 family of step-down converters. It shares architectural similarities with other low-voltage DC-DC regulators but is distinguished by its specific 1.2V fixed output and 1.2MHz frequency. It serves as a direct replacement for older linear regulators in efficiency-critical designs where space is constrained.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for LM2830 variants with different output voltages if system requirements change. Verify compatibility with alternative suppliers offering equivalent SOT-23-6 packages. Ensure substitute parts maintain similar switching frequencies to avoid redesigning passive components.
