# TPTLV70218DBVR

**TECH PUBLIC** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPTLV70218DBVR from TECH PUBLIC, in a SOT-23-5. 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 | VIN | power_in | Input supply voltage. Operating range 1.2V to 5.5V; absolute maximum -0.3V to 6.5V referenced to GND. Bypass to GND with a 1 uF to 10 uF ceramic capacitor. |
| 2 | GND | power_in | Device ground / return for the regulator and internal reference. |
| 3 | EN | input | Active-high enable input. Drive above VENH (0.7V typ, 0.9V max) to turn the regulator on; drive below VENL (0.65V typ, 0.4V min) to shut down. Absolute max -0.3V to 6V. Do not float - tie to VIN if always-on operation is desired. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to GND for mechanical robustness. |
| 5 | VOUT | power_out | Regulated output, fixed 1.8V for the -18 option, capable of up to 300 mA (typical current limit 600 mA, min 350 mA). Requires a 1 uF to 10 uF ceramic output capacitor. Active discharge (~80 ohm) pulls VOUT to ground when EN is low. |

## CAD (KiCad official)

- Symbol: `TPTLV70218DBVR`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `tptlv70218dbvr-etched.step` / `tptlv70218dbvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tptlv70218dbvr.step` / `tptlv70218dbvr.glb` are the bare package body.
