Based on the Flux knowledge base guidance:
- When selecting power regulators, ensure they support the total load current plus a 25% buffer. The LM7805 is rated for 1 A, so budget at least 1.25 A of headroom.
- Consider VOUT tolerance and line regulation accuracy (±4% typical → ±200 mV) when the output rail drives sensitive circuitry.
- Don’t forget the datasheet-specified input and output capacitors close to the regulator for stability.
Here are top LM7805 options from the Flux library:
Table
| Part Name | Package | Library Link | Datasheet |
|---|---|---|---|
| LM7805T | TO-220-3_L10.0-W4.5-P2.54-L | LM7805T | 2004071814_HGC-Huaguan-Semicon-LM7805T_C507145.pdf |
| LM7805 | TO-220-3_L10.0-W4.5-P2.54-L | LM7805 | |
| LM7805MPX/NOPB | SOT-223-4 | LM7805MPX/NOPB |
- The first two are through-hole TO-220 packages (1 A).
- The third is a compact SOT-223 variant (1.5 A rating).
