LTP3333NXT5 from Linearin, in a SOT-23-5L. 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 | IN | power_in | Supply input pin, 2.5 V to 6.0 V range. Must be closely decoupled to GND with a 1 µF or greater ceramic capacitor. Absolute maximum -0.3 V to 6.5 V. |
| 2 | GND | power_in | Ground return pin. Wide copper trace recommended for both IN and GND for stability and low noise. |
| 3 | EN | input | Enable control input, active high. VIH >= 1.4 V, VIL <= 0.4 V. Input current typ 0 µA (max 0.1 µA). Do not leave EN floating; tie to IN for always-on operation. |
| 4 | NC | unconnected | No connection. Leave floating or tie to GND per PCB convenience. |
| 5 | OUT | power_out | Regulated output pin, 3.3 V fixed (LTP3333). Up to 300 mA load, 500 mA current-limit clamp. Bypass with a 1 µF (1-2.2 µF, ESR 5-100 mΩ, X7R/X5R) ceramic capacitor to ground for stability. |
