Overview
The LM2930S-8.0/NOPB is a fixed-output positive low-dropout voltage regulator manufactured by Texas Instruments, featuring an 8 V output and housed in a TO-263-3 (D2PAK) surface-mount package. It supports input voltages up to 26 V and delivers a maximum output current of 100 mA with a typical dropout voltage of 500 mV at full load. The device operates within a temperature range of -40 °C to +125 °C and includes internal thermal shutdown and current limiting protection mechanisms.
Feature Summary
- Provides a fixed 8 V regulated output for stable power supply applications
- Operates as a low-dropout regulator with high input voltage tolerance up to 26 V
- Integrates built-in thermal overload and short-circuit current limiting protection
Applications
- Battery-powered systems requiring efficient voltage regulation
- Embedded controller logic power supplies
- General-purpose linear power regulation circuits
Procurement Notes
Verify the component marking against the official datasheet to confirm the specific 8.0 V output variant. Ensure the TO-263-3 package footprint matches the design layout. Confirm RoHS compliance status via the manufacturer's latest documentation before finalizing procurement specifications.
Selection Notes
Select this component when a fixed 8 V output is required with moderate current demands up to 100 mA. It is suitable for designs needing wide input voltage ranges and robust thermal protection. Consider alternative packages if higher current capacity or different mounting styles are necessary for the application.
Part Context
This part belongs to the LM2930 series of three-terminal positive regulators from Texas Instruments. It shares functional similarities with other LDOs but is distinguished by its specific fixed voltage options and TO-263-3 packaging. The series is designed for cost-sensitive applications requiring reliable linear regulation.
Replacement Considerations
Direct substitutes include LM2930S-8.0 without the NOPB suffix, which denotes lead-free composition. Other compatible parts may include LM2940SX-8.0/NOPB for higher current requirements or LM2930T-8.0 for through-hole mounting needs.
