LDLN030G33R from STMicroelectronics, in a TSOT-23-5. 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 | VIN | power_in | LDO supply voltage with operating input voltage range 1.6 V to 5.5 V. |
| 2 | GND | power_in | Ground reference. |
| 3 | EN | input | Enable input with logic low VIL = 0.4 V and logic high VIH = 1.2 V; set high to turn on device, low to turn off; do not leave floating. |
| 4 | PG | output | Power Good output indicator; goes low when VOUT decreases below 90 % of nominal value with 2 % hysteresis. |
| 5 | VOUT | power_out | LDO output voltage 3.3 V with maximum output current 300 mA. |
