STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DPAK
LF33CDT-TRY from STMicroelectronics, in a DPAK. 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 | INPUT | power_in | Regulator input; operating input voltage is up to 16 V (absolute maximum -0.5 to 40 V, and the regulator is in shutdown for 18 < VI < 40 V), and the 3-terminal device is fixed in the ON state. |
| 2 | GND | power_in | Ground reference, internally connected to the tab on the DPAK package. |
| 3 | OUTPUT | power_out | Regulated 3.3 V output for LF33C, up to 500 mA, current internally limited, needing a 2.2 µF output capacitor (ESR 0.1 to 10 Ω) for stability. |
