LP2992AIM5X-3.3 from Texas Instruments, in a SOT-23-5. 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 | IN | power_in | Unregulated input supply pin (2.5 V to 16 V for new chip). Bypass to GND with a 1-µF or larger capacitor placed close to the pin. |
| 2 | GND | power_in | Device ground reference for the LDO. Provides the return path for input, output, and bias currents. |
| 3 | ON/OFF | input | Active-high enable input for the LDO. Drive high (VIH ≥ 1.6 V) to enable regulation, low (VIL ≤ 0.15 V) to shutdown. Tie to VIN if unused; do not leave floating. |
| 4 | BYPASS | passive | Reference-voltage bypass pin. Connect an external capacitor (typ. 10 nF) between BYPASS and GND to reduce reference-voltage noise (achieves 30 µVRMS output noise). |
| 5 | OUT | power_out | Regulated 3.3-V output, up to 250 mA. Requires an output capacitor of 2.2 µF or larger (ESR ≤ 1 Ω) to ground for stability. |
