TPS62203

@@ -0,0 +1,48 @@+# TPS62203++**Texas Instruments** · Switching regulator (buck) · SOT-23-5++Small synchronous buck converter that steps a 2.5 to 6 V input down to a regulated rail at up to 300 mA, in a five-pin SOT-23. Both switches are integrated and it runs near 1 MHz, so the inductor and capacitors are tiny, and a power-save mode keeps efficiency high at light load for battery use. A resistor divider at FB sets the output and EN shuts it down. A compact point-of-load supply for a single sensor or subsystem.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VI | power_in | Supply voltage input pin. Recommended operating range 2.5 V to 6 V (absolute max 7 V). Requires a >=4.7 µF ceramic input capacitor to GND close to the pin. |+| 2 | GND | power_in | Device ground. All voltage measurements are referenced to this pin. |+| 3 | EN | input | Enable input. Pulling this pin to GND forces the device into shutdown. Pulling to VI enables the device. Must not be left floating and must be terminated. |+| 4 | FB | input | Feedback pin. For the fixed-output-voltage version (TPS62203 = 1.8 V fixed), connect FB directly to the output. For the adjustable version an external resistor divider sets Vout; the internal divider is disabled in that mode. |+| 5 | SW | output | Switch node. Connect the external inductor (typ. 10 µH) between this pin and the output. Internally connected to the high-side and low-side MOSFET switches. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Synchronous step-down converter |+| Input | 2.5-6 V |+| Output current | 300 mA |+| Switching freq | 1 MHz |+| Integrated FETs | Yes |+| Light load | Power-save mode |+| Package | SOT-23-5 |++## Ordering variants++- `TPS62203DBVR (adjustable, SOT-23-5)`+- `TPS62200DBVR (fixed variants)`++## CAD (KiCad official)++- Symbol: `Regulator_Switching:TPS62203DBV (KiCad official)`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (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/tps62203.pdf) (30 pp, sha256 `f6ac7e529beda007`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
