**Analog Devices** · DC-DC Converters · TSOT-23-5

LT3001ES5#TRMPBF from Analog Devices, in a TSOT-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 | EN/UVLO | input | Enable/undervoltage lockout input: pull below 0.2V to shut down, accurate 1.228V threshold with 2.5µA hysteresis current for programming a VIN UVLO via resistor divider, tie to VIN if unused. |
| 2 | GND | power_in | Ground pin, tie directly to local ground plane. |
| 3 | RFB | input | Input for external feedback resistor connected to the transformer primary SW pin, setting the output voltage (100µA regulation current); minimize trace area. |
| 4 | SW | passive | Drain of the 65V internal DMOS power switch; minimize trace area to reduce EMI and voltage spikes. |
| 5 | VIN | power_in | Input supply (4V to 36V operating) for internal circuitry and reference for the RFB feedback circuitry; bypass locally to ground with a capacitor. |
