LP2988ILDX-3.8/NOPB

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LP2988ILDX-3.8/NOPB is a fixed positive linear regulator from Texas Instruments, delivering a 3.8V output with a maximum current of 200mA. It operates within an input voltage range up to 16V and features a typical dropout voltage of 0.35V at full load. The device incorporates internal protection mechanisms including overcurrent limiting, thermal shutdown, and short-circuit protection. It functions reliably across an extended temperature range of -40°C to +125°C and utilizes an 8-WSON package for surface-mount applications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free packaging compliant with RoHS standards. Confirm the 'ILD' prefix corresponds to the industrial temperature grade and LLP-8 package variant. Ensure compatibility with existing PCB footprints for the 8-WSON form factor before procurement.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 3.8V rail is required with minimal static power consumption. It is suitable for designs where input voltages may vary significantly but require tight regulation. Consider the thermal performance in enclosed spaces due to the small package size and potential heat dissipation requirements under continuous load.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the LP2988 family of micropower LDO regulators designed for low-noise applications. It shares architectural similarities with other variants in the series, differing primarily in output voltage settings and package options. The family targets portable electronics needing long battery life and stable performance.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

LP2988ILDX-3.8/NOPB serves as the primary designation. Check for LP2988IMM-3.8/NOPB if VSSOP-8 packaging is acceptable instead of LLP-8. Verify pinout compatibility before substituting with other LDO families.
