- Wide 6 V to 26 V input range covers automotive, industrial 12 V and 24 V supply rails with a single fixed regulator
- DPAK surface-mount package enables compact, automated SMT assembly with good thermal dissipation via PCB copper pours
Applications
The LM2930S-5.0 is used in automotive electronics, industrial control systems, and battery-powered equipment requiring a stable 5 V supply from 12 V or 24 V input rails. Its 0.32 V low-dropout characteristic makes it suitable for applications where the input voltage may drop close to 5 V, such as end-of-discharge battery systems. Designers in automotive modules, sensor signal conditioning, and embedded controller power supplies select it for reliable 5 V regulation with 0.05% load regulation across varying current demands.

Frequently Asked Questions
What is the dropout voltage of the LM2930S-5.0, and how does it benefit automotive 12 V battery-powered designs?
The LM2930S-5.0 has a nominal dropout voltage of only 0.32 V, meaning it maintains a regulated 5 V output as long as the input stays above approximately 5.32 V. In automotive applications powered from a 12 V battery that may sag to 6 V during cold-crank conditions, this low-dropout characteristic ensures the 5 V rail remains stable for microcontrollers and sensors throughout the battery discharge cycle.
What load and line regulation figures does the LM2930S-5.0 achieve, and why do they matter in sensor power supply designs?
The LM2930S-5.0 achieves maximum load regulation of 0.05% and line regulation of 0.08%, meaning the output voltage stays extremely stable as current draw or input voltage changes. For precision analog sensors and ADC reference supplies, this tight regulation ensures that output variations remain well below 5 mV over the full load range, preventing measurement errors caused by supply noise or drift.
In what package does the LM2930S-5.0 come, and what thermal advantages does it offer for a 24 V industrial panel supply?
The LM2930S-5.0 is housed in a 3-pin DPAK (TO-252) surface-mount package, which allows the exposed thermal pad to be soldered directly to a PCB copper pour for efficient heat dissipation. In a 24 V to 5 V industrial panel supply, the DPAK's low thermal resistance to the board helps keep junction temperature within safe limits at moderate output currents, reducing or eliminating the need for an external heatsink compared to an axial or TO-92 package.
