5V, 300mA Isolated Step-Down Voltage Regulator D24Z3F5
This step-down voltage regulator consists of an input step-down (buck) regulator in front of an isolated DC-to-DC power module. This enables up to 300 mA at 5 V (default) or 5.5 V (selectable) out from a wide 5.5 V to 36 V input.
| Input voltage | Output voltages | Max continuous output current | Size |
|---|---|---|---|
| 5.5 V to 36 V | 5 V (default) or 5.5 V (selectable) | 300 mA | 0.4″ × 1.0″ |

Notes:
- 1
- Can operate down to around 4.6 V with reduced output current.
- 2
- Default; can be set to 5.5 V through a selection input.
- 3
- Manufacturer rating of the isolation IC. The overall assembled PCB is not certified to any particular safety standard.
- 4
- While enabled with no load. See the quiescent current graph under the description tab for more information. Can be reduced to approximately 10 µA per volt on VIN using the EN pin.
