LP2992IM5X-1.8 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 | IN | power_in | Input supply pin; use a capacitor of 1µF or larger from this pin to ground. The new-chip supply input range is 2.5 V to 16 V (absolute maximum continuous input 18 V). |
| 2 | GND | power_in | Ground reference pin for the regulator; all voltages are specified with respect to GND. |
| 3 | ON/OFF | input | Enable pin for the LDO: driving high enables the device and driving low disables it, with thresholds given in the Electrical Characteristics table; tie to VIN if unused and keep the enable voltage within 0 V to 16 V (new chip). |
| 4 | BYPASS | input | Bypass pin for low-noise operation; an external capacitor between BYPASS and ground reduces reference voltage noise, and the bypass voltage is 1.2 V. |
| 5 | OUT | power_out | Regulator output; use a capacitor of 2.2µF or larger from this pin to ground, keeping the effective output capacitance at the pin above 1µF, with output current up to 250 mA. |
