LM2788MM-1.8/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2788MM-1.8/NOPB is a step-down switching regulator manufactured by Texas Instruments, utilizing a charge pump topology to provide a fixed 1.8 V output. It operates within an input voltage range of 2.6 V to 5.5 V and delivers up to 120 mA of output current at a switching frequency of 500 kHz. The device is housed in an 8-VSSOP package and supports surface-mount installation. It functions as a positive-output regulator with a single channel, designed for efficient DC-DC conversion in compact power management applications.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm the specific suffix matches the required fixed output voltage. Check RoHS compliance status against current regulatory requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to assembly. Validate package marking against official datasheet specifications to prevent counterfeit substitution.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8 V output is required from inputs between 2.6 V and 5.5 V. It is appropriate for designs prioritizing simplicity over adjustable output flexibility. Consider the 120 mA current limit for load requirements. The 500 kHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Evaluate thermal performance within the 8-VSSOP package for the intended power dissipation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2788 family of charge pump regulators from Texas Instruments.
