LTC1983ES6-5#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 | VIN | power_in | Charge pump input voltage, which may be between 2.3V and 5.5V; bypass with a ≥4.7µF low ESR capacitor as close as possible to the pin. |
| 2 | VOUT | power_out | Regulated output voltage of the IC; bypass with a ≥4.7µF low ESR capacitor as close as possible to the pin. |
| 3 | C+ | passive | Charge pump flying capacitor positive terminal, switched between VIN and GND and connected to VCC during shutdown. |
| 4 | C- | passive | Charge pump flying capacitor negative terminal, switched between GND and VOUT and connected to GND during shutdown. |
| 5 | GND | power_in | Signal and power ground for the 6-pin SOT-23 package, which should be tied to a ground plane for best performance. |
| 6 | SHDN | input | Shutdown input: grounding this pin shuts down the IC, tie to VIN to enable, and it must not be pulled above VIN or below GND. |
