LP2985A-30DBVR 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 | VIN | power_in | Input supply voltage ranging from 2.5 V to 16 V (new chip) or 2.2 V to 16 V (legacy chip) with 1 µF minimum bypass capacitor to ground required. |
| 2 | GND | power_in | Ground reference and return path for all input, output, bypass, and internal circuit current. |
| 3 | ON/OFF | input | Active-high enable pin with high threshold 0.85 V (new chip) or 1.4 V (legacy chip) and low threshold 0.72 V (new chip) or 0.55 V (legacy chip); internal pull-down circuit in new chip activates when disabled; tie to VIN if shutdown feature is not used. |
| 4 | BYPASS | bidirectional | High-impedance low-noise bypass pin for internal bandgap reference biased in microamperes requiring 10 nF capacitor to ground to reduce output voltage noise to 30 µVRMS and improve PSRR. |
| 5 | VOUT | output | Regulated output voltage from 1.2 V to 5.0 V (new chip) or 1.2 V to 10.0 V (legacy chip) delivering 0 to 150 mA continuous load current with 2.2 µF minimum output capacitor required for stability. |
