TPS79650DCQR
Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-6
TPS79650DCQR 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 pin: driving EN high turns on the regulator, driving it low puts the regulator into shutdown, and EN can be connected to IN if not used. |
| 2 | IN | power_in | Input to the device. |
| 3 | GND | power_in | Regulator ground. |
| 4 | OUT | power_out | Output of the regulator. |
| 5 | NR/NC | passive | On the legacy chip this is the noise-reduction pin, where an external capacitor bypasses internal band-gap noise to improve PSRR and reduce output noise; on the new chip it is not internally connected and must be left open or tied to GND. |
| 6 | GND | power_in | Tab of the SOT-223 package, regulator ground, same net as pin 3. |
