Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
LP2985IM5-2.8 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 | input | Input voltage pin; the operating supply range is 2.5 V to 16 V, and the recommended minimum VIN is the greater of 3.1 V or VOUT(max) plus the maximum rated dropout at the operating load current. |
| 2 | GND | power_in | Common ground pin connected to the device substrate. |
| 3 | ON/OFF | input | Logic-high enable input; the recommended ON/OFF voltage range is 0 V to VIN. |
| 4 | BYPASS | bidirectional | Bypass capacitor connection for low-noise operation; adding a 10-nF bypass capacitor reduces output noise to 30 µVRMS in a 30-kHz bandwidth. |
| 5 | OUT | output | Regulated output voltage; output current is ensured to 150 mA and the output is short-circuit protected. |
