LT1613CS5#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 | SW | output | Switch pin for connecting the inductor and diode; minimize the trace area at this pin to keep EMI down. |
| 2 | GND | power_in | Ground pin that must be tied directly to the local ground plane. |
| 3 | FB | input | Feedback pin with a 1.23V reference that receives the resistive divider tap, with VOUT set by VOUT = 1.23V(1 + R1/R2) and trace area kept minimal. |
| 4 | SHDN | input | Shutdown pin that must be tied to 1V or more to enable the device and grounded to shut it down; the SHDN voltage absolute maximum is 10V. |
| 5 | VIN | power_in | Input supply pin that must be locally bypassed; the absolute maximum VIN rating is 10V. |
