L5973D013TR from STMicroelectronics, in a SOIC-8. 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 | Regulator output; adjustable from 1.235 V to 35 V. |
| 2 | SYNC | bidirectional | Master/slave synchronization pin; operates as master output to 3 V at 3 mA source current or slave input with thresholds of 0.74 V (low) to 2.5 VREF (high). |
| 3 | INH | input | Inhibit control input (active high) to disable the device; must be grounded if unused; internal pull-up present; voltage range -0.3 to VCC. |
| 4 | COMP | output | Error amplifier output for frequency compensation; output range 0.4 V to 3.5 V; maximum analog pin rating 4 V. |
| 5 | FB | input | Feedback input for output voltage setting; direct connection yields 1.235 V output, external resistive divider required for higher voltages; maximum analog pin rating 4 V. |
| 6 | VREF | power_in | 3.3 V reference voltage output (typical 3.3 V, range 3.234 to 3.366 V at 25°C); no decoupling capacitor required for stability. |
| 7 | GND | power_in | Ground reference connection. |
| 8 | VCC | power_in | Unregulated DC input voltage; operating range 4 V to 36 V; absolute maximum 40 V. |
