# TPS71550DCKR-TP

**TECH PUBLIC** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC-70-5

TPS71550DCKR-TP from TECH PUBLIC, in a SC-70-5. 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 | NC | unconnected | No internal connection. Leave floating or tie to GND on the board. |
| 2 | GND | power_in | Device ground reference. All output/input voltages are referenced to this pin. |
| 3 | NC | unconnected | No internal connection. Leave floating or tie to GND on the board. |
| 4 | IN | power_in | Unregulated supply input, 2.7 V to 24 V (28 V abs max). Bypass with a ≥1 µF capacitor to GND placed close to the pin. |
| 5 | OUT | power_out | Regulated 5.0 V output, up to 50 mA drive (current limit 50-150 mA). Requires a ≥1 µF output capacitor to GND for stability. |

## CAD (KiCad official)

- Symbol: `TPS71550DCKR-TP`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SC-70-5 (KiCad packages3D, STEP)
- 3D model files: `tps71550dckr-tp-etched.step` / `tps71550dckr-tp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps71550dckr-tp.step` / `tps71550dckr-tp.glb` are the bare package body.
