# LM2832ZMY

**Texas Instruments** · DC-DC Converters · MSOP-8-EP

LM2832ZMY from Texas Instruments, in a MSOP-8-EP. 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 | VIND | power_in | Power input supply pin for the regulator; the operating input range is 3V to 5.5V. |
| 2 | VINA | power_in | Control circuitry supply voltage; connect VINA to VIND on the PC board. |
| 3 | GND | power_in | Signal and power ground; place the bottom resistor of the feedback network as close as possible to this pin. |
| 4 | EN | input | Enable control input where logic high enables operation; do not let this pin float or allow it to exceed VIN + 0.3V. |
| 5 | GND | power_in | Signal and power ground; place the bottom resistor of the feedback network as close as possible to this pin. |
| 6 | FB | input | Feedback pin; connect to an external resistor divider to set the output voltage. |
| 7 | GND | power_in | Signal and power ground; place the bottom resistor of the feedback network as close as possible to this pin. |
| 8 | SW | output | Output switch; connect to the inductor and catch diode. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `LM2832ZMY`
- Footprint: `Package_SO:MSOP-8-1EP_3x3mm_P0.65mm_EP1.5x1.8mm`
- 3D model: MSOP-8-EP (KiCad packages3D, STEP)
- 3D model files: `lm2832zmy-etched.step` / `lm2832zmy-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm2832zmy.step` / `lm2832zmy.glb` are the bare package body.
