LM2665M6X from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | V+ | power_in | In voltage-doubler mode: positive supply input (2.5 V to 5.5 V). In voltage-splitter mode: positive voltage output (V_IN/2). Absolute max V+ to GND is 5.8 V. |
| 2 | GND | power_in | Power supply ground reference for the device in both doubler and splitter configurations. |
| 3 | CAP- | passive | Negative terminal of the external flying (charge-pump) capacitor C1. Typically 3.3 µF, low-ESR (<0.3 Ω). |
| 4 | SD | input | Shutdown control input. Tie to GND for normal operation; drive high (>=40% of V+, min 2 V) to place device into 1 µA shutdown. Low threshold <=20% of V+ (0.8 V max). |
| 5 | OUT | power_out | In voltage-doubler mode: positive doubled voltage output (~2*V_IN), up to 40 mA. In voltage-splitter mode: positive supply input (1.8 V to 11 V). Absolute max OUT to GND is 11.6 V. |
| 6 | CAP+ | passive | Positive terminal of the external flying (charge-pump) capacitor C1. Typically 3.3 µF, low-ESR (<0.3 Ω). |
