TPS79618DCQR from Texas Instruments, in a SOT-223-6. 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 | EN | input | Enable pin (active high). Drive EN above VEN(HI) to turn on the regulator; drive below VEN(LOW) to place the device in shutdown (ISHDN typically 0.07µA to 1µA max). If unused, connect EN to IN. |
| 2 | IN | power_in | Regulator input supply, 2.7V to 5.5V (old chip) or 2.7V to 6.0V (new chip); requires a 2.2µF or larger ceramic bypass capacitor to GND close to the device. |
| 3 | GND | power_in | Regulator ground return; also connected to the package tab (pin 6) for thermal and electrical grounding. |
| 4 | OUT | power_out | Regulated output of the LDO, rated for up to 1A continuous output current; requires a minimum 1µF ceramic output capacitor to GND for loop stability. |
| 5 | NR/NC | passive | On the fixed-voltage 'old chip' die, this is the Noise-Reduction (NR) pin: an external capacitor (0.1µF or smaller, connected through an internal 250kΩ resistor to the bandgap reference) can be added here to lower output noise and improve PSRR. On the fixed-voltage 'new chip' die, this position is No-Connect (N/C) and must be left open or tied to GND; the new-chip die has no NR function. |
| 6 | GND (Tab) | power_in | Exposed mounting tab of the SOT-223-6 package; electrically grounded and must be soldered to the PCB copper/ground plane to provide the primary thermal conduction path for the device. |
