D24V3Fx Step-Down Voltage Regulators
This family of small switching step-down voltage regulators efficiently generates lower output voltages from input voltages as high as 42 V with a maximum current of 300 mA.
| Regulator | Output voltage | Typical max output current1 | Input voltage range2 | Size | Special features | Price |
|---|---|---|---|---|---|---|
| #2097: D24V3F3 | 3.3 V | 300 mA | 4.3 V – 42 V | 0.4″ × 0.5″ | Over-temperature shutoff, over-current shutoff |

| #2098: D24V3F5 | 5 V | 7 V – 42 V | $8.49 | |||
| #2099: D24V3F9 | 9 V | 11 V – 42 V | $8.49 | |||
| #2100: D24V3F12 | 12 V | 14.5 V – 42 V | $8.49 | |||

Note: We recommend our newer 600 mA D36V6Fx family of step-down voltage regulators over these ones. They offer a wider 4 V to 50 V operating voltage range and lower quiescent current, and they can generally be used as drop-in replacements for this product (they use the same PCB, just populated with different parts). Please also consider our 500 mA D24V5Fx and 1 A D24V10Fx families for synchronous alternatives that offer similar functionality with much lower dropout voltages and higher efficiencies at light loads. All of these newer families also have more output voltage options available.
