LTP3558-33XT4
Linearin · Linear Voltage Regulators (LDO) · SOT-89-3
LTP3558-33XT4 from Linearin, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground. |
| 2 | IN | power_in | Supply input pin; must be closely decoupled to GND with a 1μF or greater ceramic capacitor. |
| 3 | OUT | power_out | Output pin; bypass with a 1μF or greater ceramic capacitor from this pin to ground. |
