LP2985IM5-6.1 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 with recommended operating range of 3.1V-16V (legacy chip) or 2.5V-16V (new chip); requires input capacitor ≥1µF to ground. |
| 2 | GND | power_in | Ground reference providing return path for input and output capacitors and load current. |
| 3 | ON/OFF | input | Active-high enable input; output enabled when VON/OFF > 1.4V (legacy chip) or 0.85V (new chip), disabled when VON/OFF < 0.55V (legacy chip) or 0.15V (new chip); tie to VIN if unused. |
| 4 | BYPASS | bidirectional | Bypass pin for internal bandgap reference; connect 10nF external capacitor to ground to achieve 30µVRMS output noise (300Hz-50kHz bandwidth) and PSRR >70dB at 1kHz. |
| 5 | VOUT | output | Regulated output voltage pin capable of delivering 150mA maximum continuous current with output tolerance of ±1.5% (legacy standard grade) or ±1% (new chip); requires output capacitor ≥2.2µF to ground. |
