LM1501BGR-ADJ from HTC Korea TAEJIN Tech, in a TO-263-5. 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 | VIN | power_in | Operating input voltage pin; the recommended supply voltage is 40V maximum and the absolute maximum input supply voltage is 45V. |
| 2 | OUTPUT | output | Switching output that drives the external inductor; the steady-state output-to-ground limit is -1V and the internal switch current limit is 6.9A peak. |
| 3 | GND | power_in | Ground reference pin; single-point grounding or a ground plane is recommended for best results. |
| 4 | FB | input | Output voltage feedback control; the feedback pin voltage is rated from -0.3V to +25V, and the adjustable version sets VOUT = VFB(1+R2/R1) with VFB = 1.23V. |
| 5 | ON/OFF | input | Shutdown control; the pin input voltage is rated from -0.3V to +25V, with a 0.6V threshold for regulator ON and a 2.0V threshold for regulator OFF. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
