LD39200DPUR from STMicroelectronics, in a DFN-8(4x4). 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 | power_out | Output voltage; both output pins 1 and 2 must be connected together on the board. |
| 2 | OUT | power_out | Output voltage; both output pins 1 and 2 must be connected together on the board. |
| 3 | ADJ/SENSE | input | Adjustable pin connected to external resistor divider to set output voltage from 0.5 V. |
| 4 | GND | power_in | Ground reference. |
| 5 | PG | output | Power good output flag with open-drain driver; high impedance when VOUT > 0.92VOUT, low impedance when VOUT < 0.80VOUT. |
| 6 | EN | input | Enable logic input; device ON when voltage > 1.2 V, OFF when voltage < 0.5 V, draws 10 nA typical. |
| 7 | IN | power_in | Input supply voltage with 1.25 V to 6.0 V operating range; both input pins 7 and 8 must be connected together on the board. |
| 8 | IN | power_in | Input supply voltage with 1.25 V to 6.0 V operating range; both input pins 7 and 8 must be connected together on the board. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
