XTR117AIDRBR from Texas Instruments, in a WSON-8-EP(3x3). 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 | NC | unconnected | No connection. |
| 2 | IIN | input | Current input pin, sets output current with 100:1 gain (IO = 100 × IIN) referenced to IRET potential. |
| 3 | IRET | power_in | Local ground return reference for voltage regulator (VREG) and current input (IIN) circuits. |
| 4 | IO | output | Regulated 4-20mA current loop output, limited to maximum 32mA by internal current limit circuit. |
| 5 | E | input | External transistor emitter connection, connects to emitter of external NPN pass transistor (recommended TIP29C or equivalent). |
| 6 | B | output | External transistor base connection, output drives base of external NPN pass transistor for output current regulation. |
| 7 | V+ | power_in | Loop power supply input, recommended operating range 7.5V to 40V, absolute maximum 40V. |
| 8 | VREG | output | 5V regulated voltage output from on-chip regulator, capable of supplying external circuits with maximum short-circuit current of 12mA. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
