HG1507MDT-12 from HGSEMI, in a TO-252-4. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Supply input pin. Requires a 4.5 V to 40 V DC input (15 V to 40 V for the -12 version). Bypass to GND with a large-value ceramic/electrolytic capacitor (typ. 470 uF/50 V in parallel with 105 ceramic) to suppress supply noise. |
| 2 | OUTPUT | output | Internal power-switch (emitter) output - a switching node that drives the external inductor/catch-diode/output-capacitor filter to deliver up to 3 A load current. Saturation voltage ~1.3-1.5 V at IOUT=3 A. |
| 3 | GND | power_in | Ground pin (also connected to the metal tab). Route on the output-capacitor return outside the Schottky-diode current path to keep switching spikes off the control ground. |
| 4 | FEEDBACK | input | Voltage-feedback input to the internal error amplifier. On the fixed 12 V version this pin is tied directly to the regulated output; the internal reference threshold is 1.23 V (with fixed internal divider setting the 12 V output). |
| 5 | ON_OFF | input | Enable input with hysteresis. Pull LOW (< 0.8 V) or leave floating (defaults low) to enable the regulator; pull HIGH (> 1.4 V, up to VIN) to shut it down. Standby current ISTBY ~80 uA (max 200 uA) when disabled. |
