LP2951CMMX from Texas Instruments, in a VSSOP-8-0.65mm. 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 | OUT | output | Regulated output voltage, 5V/3V/3.3V nominal with ±0.5% typical accuracy and 100mA maximum output current |
| 2 | SENSE | input | Output voltage sense input; connect to VOUT for proper feedback regulation and accurate output voltage control |
| 3 | SHUTDOWN | input | Shutdown control input; regulator enabled at voltage <0.6V, disabled when >2.0V with 30µA to 50µA input current |
| 4 | GND | power_in | Ground reference connection for device circuit return path |
| 5 | ERROR | tri_state | Error flag open-collector output; goes low when VOUT drops more than 5% below nominal voltage during dropout condition |
| 6 | VTAP | output | Internal reference divider tap output; nominal 1.235V typical voltage for programming external feedback resistor network |
| 7 | FEEDBACK | input | Feedback input with high impedance; 20nA typical bias current, accepts 1.235V to 29V voltage range for output programming |
| 8 | IN | power_in | Input supply voltage, 2.3V to 30V operating range with 75µA typical quiescent current and 50mV to 450mV dropout voltage |
