LT1790BIS6-2.5#TRPBF from Analog Devices, in a TSOT-23-6. 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 | GND | power_in | Ground reference pin; the datasheet's typical application ties the 1µF output capacitor to pins 1 and 2 as ground. |
| 2 | GND | power_in | Ground pin, which the typical application ties to the output capacitor return alongside pin 1. |
| 3 | DNC | unconnected | Do Not Connect; the datasheet says this pin must not be connected. |
| 4 | VIN | power_in | Supply input, specified for 2.6V ≤ VIN ≤ 18V in operation and rated to 20V absolute maximum input voltage. |
| 5 | DNC | unconnected | Do Not Connect; the datasheet says this pin must not be connected. |
| 6 | VOUT | power_out | Reference output, 2.5V for the LT1790-2.5, which can both source and sink current, with load regulation specified at 5mA source and 1mA sink. |
