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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-223-6 |+| Category | Power Management (PMIC) |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `TPS79618DCQR`+- Footprint: `Package_TO_SOT_SMD:SOT-223-6`+- 3D model: SOT-223-6 (KiCad packages3D, STEP)+- 3D model files: `tps79618dcqr-etched.step` / `tps79618dcqr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps79618dcqr.step` / `tps79618dcqr.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/tps796) (49 pp, sha256 `b651d7f91b5b2963`, retrieved 2026-09-23, tier: lcsc)+- **Datasheet language:** Chinese.
