LT1615ES5#TRPBF 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 | SW | output | Switch pin, the collector of the internal NPN power switch, with the metal trace area kept minimal to reduce EMI; the SW voltage absolute maximum is 36V. |
| 2 | GND | power_in | Ground pin that must be tied directly to the local ground plane. |
| 3 | FB | input | Feedback pin that sets the output voltage through the external R1 and R2 divider (R1/R2 = VOUT/1.23V − 1), with a maximum of 1mA current into the pin. |
| 4 | SHDN | input | Shutdown pin that must be tied to 0.9V or higher to enable the device and below 0.25V to turn it off, with a 15V absolute maximum rating. |
| 5 | VIN | power_in | Input supply pin that must be bypassed with a capacitor as close to the device as possible, with a 15V absolute maximum rating and a minimum input of 1.2V for LT1615 (1.0V for LT1615-1). |
