TPS79501DCQ from Texas Instruments, in a SOT-223-6. 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 | EN | input | Enable input, active high and TTL/CMOS compatible; drive low to put the regulator in shutdown, and it may be tied to IN if shutdown is not needed (enable voltage range 0 V to 5.5 V on the old die, 0 V to 6.0 V on the new die). |
| 2 | IN | power_in | Regulator input supply, operating from 2.7 V to 5.5 V on the old die or 2.7 V to 6.0 V on the new die, with absolute maximum input of 6 V (old die) or 6.5 V (new die). |
| 3 | GND | power_in | Regulator ground; the datasheet lists this pin together with pin 6 (tab) as the ground connection. |
| 4 | OUT | power_out | Regulator output, rated for 0 to 500 mA load current, with at least a 1 µF ceramic output capacitor required for stability and placed as close to this pin as possible. |
| 5 | FB | input | Feedback input for the adjustable TPS79501 that sets the output via an external resistor divider from OUT, referenced to the 1.225 V internal bandgap (FB pin current 1 µA max at VFB = 1.225 V); keep leakage low because FB leakage adds output error. |
| 6 | GND | power_in | Tab of the SOT-223 package, electrically connected to GND; solder it to a large ground copper area to maximize thermal performance. |
