LP2982IM5-3.3 from Texas Instruments, 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 | Input supply pin; the new chip accepts 2.5 V to 16 V on VIN, and a capacitor of 1 µF or larger should be placed from this pin to ground. |
| 2 | GND | power_in | Ground reference pin for the LDO. |
| 3 | ON/OFF | input | Enable pin: driving it high enables the regulator and driving it low disables it, with high and low thresholds given in the Electrical Characteristics table; tie to VIN if unused. |
| 4 | BYPASS | bidirectional | Noise-reduction node: an external capacitor between BYPASS and ground reduces reference voltage noise (30 µVRMS with a 10 nF bypass capacitor per the features list). |
| 5 | VOUT | power_out | Regulator output; use a capacitor of 2.2 µF or larger to ground, and the effective capacitance at the pin must stay above 1 µF after the stated 50% derating. |
