LM3880QMFX-1AD 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 | VCC | power_in | Input supply pin. Recommended operating range 2.7 V to 5.5 V (absolute max 6 V). Typical quiescent current 25 µA. Bypass with a local decoupling capacitor to GND. |
| 2 | GND | power_in | Device ground reference for VCC and all logic thresholds. |
| 3 | EN | input | Precision enable input. Threshold VEN typ 1.25 V (min 1.0 V, max 1.4 V) with a 7 µA internal pull-up current. Driving EN high starts the power-up sequence; pulling EN low starts the power-down sequence. |
| 4 | FLAG3 | output | Open-drain sequenced output 3. Released last during power-up (after td3) and pulled low first during power-down. Drives the enable/shutdown pin of a downstream regulator. Absolute-max pull-up voltage 6 V (or VCC+0.3 V under recommended operation); VOL ≤ 0.4 V at IFLAG = 1.2 mA; max sink current 50 mA. |
| 5 | FLAG2 | output | Open-drain sequenced output 2. Released after FLAG1 (delay td2) during power-up and pulled low after FLAG3 during power-down. VOL ≤ 0.4 V at IFLAG = 1.2 mA; max sink current 50 mA; pull-up allowed to a separate rail up to 6 V absolute max. |
| 6 | FLAG1 | output | Open-drain sequenced output 1. Released first during power-up (after td1 from EN rising) and pulled low last during power-down. VOL ≤ 0.4 V at IFLAG = 1.2 mA; leakage typ 1 nA at 3.3 V; max sink current 50 mA. |
