LP2992IM5-1.5 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 | Input supply pin. Operating range 2.5V to 16V (18V absolute max for new chip). Requires a 1µF or larger ceramic capacitor to GND placed close to the pin. |
| 2 | GND | power_in | Device ground reference. All bypass, input, and output capacitor return currents flow through this pin. |
| 3 | ON/OFF | input | Enable pin for the LDO. Driving high enables the regulator; driving low places the device into shutdown (typ 1.12µA new chip / 0.01µA legacy). Absolute max 18V; tie to VIN if enable is unused. |
| 4 | BYPASS | passive | Reference-noise bypass pin. Connect an external capacitor (typically 10nF) from BYPASS to GND to lower reference voltage noise and achieve the 30µVRMS output-noise specification. Internal bias node - do not drive; VBYPASS max 3V. |
| 5 | OUT | power_out | Regulated 1.5V output, up to 250mA load current. Requires a 2.2µF or larger ceramic output capacitor to GND (effective ≥1µF after derating). Internally current-limited and thermally protected. |
