LR7530-T from LR, in a SOT-23-3. 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 | VSS | power_in | Ground reference (GND). All voltages are referenced to this pin. |
| 2 | VOUT | power_out | Regulated output voltage. Nominal 3.0V (tolerance ±2%), able to source up to 100mA (150mA abs max). Requires a 1-10uF output capacitor placed close to the pin. |
| 3 | VIN | power_in | Unregulated input supply. Operating range up to 24V (absolute maximum 32V). Requires a bypass capacitor (1-10uF), and a ~10Ω series resistor is recommended to absorb input voltage spikes. |
