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 | CB | passive | Bootstrap capacitor pin providing the high-side switch FET gate bias voltage. Connect a bootstrap capacitor (CBOOT) between CB and SW. Absolute max: CB-to-SW voltage 7 V. |+| 2 | GND | power_in | Device ground connection. Provides return path for both control circuitry and power stage. |+| 3 | FB | input | Feedback input pin. Set output voltage divider ratio so that VOUT = VFB(1+R1/R2) with VFB = 0.765 V nominal (0.747-0.782 V). Divider resistors should be in the 100 Ω to 10 kΩ range to avoid input bias errors (IFB ≈ 0.1 µA typical). Absolute max: -0.3 V to +5 V. |+| 4 | SHDN | input | Active-low logic-level shutdown input (overbar in datasheet). Pull to GND to disable, pull high to enable (VSHDN on threshold ≥2.3 V, off threshold ≤0.3 V). Tie to VIN or leave open if unused. An RC network on this pin can implement soft-start. Absolute max: -0.3 V to (VIN+0.3 V), <45 V. |+| 5 | VIN | power_in | Power input voltage pin. Operating range 4.5 V to 42 V; absolute max +45 V. Bypass locally with an input capacitor (CIN) to GND. |+| 6 | SW | power_out | Power FET switching output. Connect to the external inductor, catch diode, and CBOOT bootstrap capacitor. Rated up to 42 V; internal switch RDSON ≈ 0.9 Ω typical; current limit ≈ 1.15 A typical. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `LMR14206XMKXXMK`+- `LMR14206XMKXXMKX`++## CAD (KiCad official)++- Symbol: `LMR14206XMKX`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/lmr14206xmkx.pdf) (17 pp, sha256 `cf0a3e1c2f2b5530`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
