LM2788MM-2.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2788MM-2.0/NOPB is a fixed-output charge pump switching regulator manufactured by Texas Instruments, designed for step-down voltage conversion applications. It provides a regulated 2V output with a maximum continuous current capability of 120mA. The device operates from an input voltage range of 2.6V to 5.5V and utilizes a fixed switching frequency of 500kHz. Packaged in an 8-VSSOP surface-mount case, it supports operation across an ambient temperature range of -40°C to +85°C. This component integrates synchronous rectification logic internally to enhance efficiency within its specified operating parameters.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per manufacturer documentation. Confirm package designation matches the 8-VSSOP physical outline required for your PCB footprint. Check current lifecycle status, as this part may be discontinued or subject to long lead times depending on regional distributor availability. Ensure input voltage requirements align with the 2.6V minimum threshold before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2V output is required from a single-cell lithium-ion or similar battery source. It is appropriate for designs prioritizing simplicity over adjustable output flexibility. Consider the 120mA current limit against peak load demands to prevent dropout. The fixed frequency simplifies EMI filtering calculations compared to variable frequency controllers. Evaluate thermal performance within the 8-VSSOP package for the expected power dissipation levels.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2788 family of charge pump regulators from Texas Instruments. It shares architectural similarities with other fixed-output variants like the LM2788MM-1.5/NOPB and LM2788MM-1.8/NOPB, differing primarily in the internal feedback network setting the output voltage. The family targets ultra-low cost, space-constrained applications where discrete solutions are impractical.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct functional substitutes include LM2788MM-1.5/NOPB and LM2788MM-1.8/NOPB if different fixed voltages are acceptable. Verify pin compatibility and thermal characteristics when considering alternative manufacturers. No direct drop-in replacements with identical electrical specifications are widely documented outside the LM2788 series.
