Overview
The LM2930SX-5.0/NOPB is a fixed-output positive low-dropout voltage regulator manufactured by Texas Instruments. It provides a stable 5 V output with a maximum load current of 100 mA. The device utilizes a D2PAK-3 (TO-263-3) surface-mount package, suitable for high-current applications requiring compact footprints. It operates within an extended temperature range from -40 °C to +125 °C. The regulator features internal thermal overload and current limit protection to ensure reliability under fault conditions.
Feature Summary
- Fixed 5 V output voltage regulation
- Internal thermal shutdown and current limiting protection
- High ripple rejection ratio for noise-sensitive circuits
Applications
- Battery-powered systems requiring efficient voltage regulation
- Portable equipment with limited power supply headroom
- General-purpose linear regulation in industrial control modules
Procurement Notes
Verify the complete part number including the suffix /NOPB to confirm lead-free compliance and RoHS status. Ensure the ordering code matches the specific package variant D2PAK-3. Cross-reference the manufacturer datasheet revision to confirm pinout compatibility before integration into existing designs.
Selection Notes
Select this component when a fixed 5 V rail is required with up to 100 mA load capability. The D2PAK-3 package offers superior thermal dissipation compared to smaller SOT packages. Consider input voltage headroom requirements relative to the dropout voltage characteristics specified in the electrical tables of the official datasheet.
Part Context
This part belongs to the LM2930 family of three-terminal positive regulators. It serves as a direct replacement for older National Semiconductor versions with updated manufacturing processes. The /NOPB suffix indicates a non-phosphorus lead-free product compliant with environmental directives.
Replacement Considerations
Direct equivalents include LM2930S-5.0 and LM2930T-5.0 from Texas Instruments or National Semiconductor. Verify package type consistency between TO-220, TO-263, and TO-252 variants during substitution.
