LP3996SD-3333 from Texas Instruments, in a WSON-10-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Voltage Supply Input operating from 2.0V to 6.0V; requires 1 µF input capacitor to GND. |
| 2 | EN1 | input | Active-high enable input for Regulator 1; high enables output, low disables output. |
| 3 | EN2 | input | Active-high enable input for Regulator 2; high enables output, low disables output. |
| 4 | CBYP | passive | Internal voltage reference bypass pin; connect 10nF capacitor to GND for noise reduction and improved transient response, or leave open. |
| 5 | SET | passive | Programmable delay input for POR output; connect capacitor to GND to set delay time, or leave open for no delay. |
| 6 | GND | power_in | Common ground pin connected to exposed thermal pad. |
| 7 | N/C | unconnected | No connection pin; must remain unconnected. |
| 8 | POR | tri_state | Open-drain power-on-reset output, active low when VOUT2 falls below 90% of nominal; requires external pull-up resistor. |
| 9 | VOUT2 | power_out | Regulated output of 3.3V from Regulator 2 supplying up to 300 mA; requires 1 µF output capacitor to GND. |
| 10 | VOUT1 | power_out | Regulated output of 3.3V from Regulator 1 supplying up to 150 mA; requires 1 µF output capacitor to GND. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
