LM2594N-5.0 from Texas Instruments, in a PDIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connection; the datasheet notes NC pins are not internally connected but must be soldered to the PCB for best heat transfer. |
| 2 | NC | unconnected | No connection; the datasheet notes NC pins are not internally connected but must be soldered to the PCB for best heat transfer. |
| 3 | NC | unconnected | No connection; the datasheet notes NC pins are not internally connected but must be soldered to the PCB for best heat transfer. |
| 4 | Feedback | input | Senses the regulated output voltage to complete the feedback loop. |
| 5 | ON/OFF | input | Logic-level shutdown: pulling below about 1.3 V turns the regulator on and pulling above 1.3 V (up to a maximum of 25 V) shuts it down, reducing total input supply current to about 80 µA; leave open or tie to ground to keep the regulator always on. |
| 6 | Ground | power_in | Circuit ground. |
| 7 | +VIN | power_in | Positive input supply for the switching regulator, requiring a suitable input bypass capacitor at this pin; recommended operating supply is 4.5 V to 40 V for LM2594 (60 V for LM2594HV) with absolute maximum of 45 V for LM2594. |
| 8 | Output | output | Internal switch output that swings between (+VIN − VSAT) and approximately −0.5 V with duty cycle VOUT/VIN; keep the PCB copper area on this pin to a minimum to limit coupling to sensitive circuitry. |
