Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
LP3988IMF-3.0 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 | power_in | Input voltage supply to the low-dropout regulator; operating range 2.5 V to 6 V. |
| 2 | GND | power_in | Ground reference; common ground for the device. |
| 3 | EN | input | Logic-controlled enable input; high level enables regulator operation. |
| 4 | PG | tri_state | Open-drain Power Good flag output; active low indicates output voltage out of tolerance condition. |
| 5 | OUT | output | Regulated output voltage of the low-dropout regulator; capable of supplying up to 150 mA. |
