LOWPOWER · Linear Voltage Regulators (LDO) · SOT-23-5
LP3984-15B5F from LOWPOWER, in a SOT-23-5. 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 | VIN | power_in | Power input voltage, with the datasheet's recommended supply range of 2.5V to 5.5V; the input capacitor must sit no more than 0.5 inch from this pin. |
| 2 | GND | power_in | Ground reference pin; the datasheet gives no further electrical limit for this pin. |
| 3 | EN | input | Active-high chip enable: the LDO turns on when EN is above 1.4V and shuts down when EN falls below 0.4V, with EN input voltage rated 0V to VIN+0.3V. |
| 4 | NC | unconnected | No connection, as stated in the datasheet pin description. |
| 5 | VOUT | power_out | Regulated output rated for 300mA output loading current; use a ceramic output capacitor of at least 1µF with ESR above 25mΩ, placed no more than 0.5 inch from this pin. |
