# LM3525MX-L

**Texas Instruments** · Power Distribution Switches · SOIC-8

LM3525MX-L from Texas Instruments, in a SOIC-8. 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 | EN | input | Enable input for logic-compatible control; active-low enable for the LM3525-L variant. |
| 2 | FLG | output | Fault Flag output, active-low open-drain; indicates overcurrent condition, UVLO, or thermal shutdown. |
| 3 | GND | power_in | Ground reference for the device. |
| 4 | NC | unconnected | Not internally connected; no internal connection within the IC. |
| 5 | NC | unconnected | Not internally connected; no internal connection within the IC. |
| 6 | OUT | output | Switch output; drain of the high-side output MOSFET; must be tied together with pin 8. |
| 7 | IN | power_in | Supply input for the power switch and IC control circuitry; accepts 2.7V to 5.5V. |
| 8 | OUT | output | Switch output; drain of the high-side output MOSFET; must be tied together with pin 6. |
