Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
LP3985IM5-4.7 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 of the LDO; recommended VIN is 2.5 V to 6 V, and the absolute maximum rating on IN is -0.3 V to 6.5 V, referenced to GND. |
| 2 | GND | power_in | Common ground; all voltages in the absolute maximum ratings are referenced to the GND pin. |
| 3 | EN | input | Enable input logic, enable high; the ON/OFF input voltage is specified from 0 V to VIN. |
| 4 | BYPASS | bidirectional | Optional bypass capacitor for noise reduction, which reduces output noise without slowing load transient response. |
| 5 | OUT | output | Output voltage of the LDO; rated for output current up to 150 mA, with absolute maximum of -0.3 V to (VIN + 0.3) V and below 6.5 V. |
