LT1790BIS6-2.048#TRMPBF 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 pin, tied to circuit ground and internally common with pin 2. |
| 2 | GND | power_in | Ground pin, tied to circuit ground and internally common with pin 1. |
| 3 | DNC | unconnected | Do not connect. |
| 4 | VIN | power_in | Supply input, 2.6V to 18V per the typical application (20V absolute maximum), bypassed with 0.1µF. |
| 5 | DNC | unconnected | Do not connect. |
| 6 | VOUT | power_out | Reference output (2.048V for the -2.048 option), able to source and sink current, with a 1µF output capacitor shown in the typical application. |
