LD1085xx is a low dropout 3A adjustable and fixed output voltage positive voltage regulator.
The LD1085xx is a low dropout positive voltage regulator capable of providing up to 3 A of output current. It offers both adjustable and fixed output voltage options (1.5V, 1.8V, 2.5V, 3.3V, 5V, 12V) and is available in TO-220, TO-220FP, DPAK, D?PAK, and D?PAK/A packages. The device is pin-to-pin compatible with standard adjustable regulators but provides better performance in terms of dropout voltage and output tolerance.
| Output current | 3 A |
|---|---|
| Typical dropout voltage | 1.3 V |
| Operating temperature range | -40 °C to 125 °C |
| Output voltage tolerance | + 1% at 25°C |
| Input voltage | 30 V |
| Storage temperature range | -55 to +150 °C |
The device supports fixed output voltages of 1.5V, 1.8V, 2.5V, 3.3V, 5V, and 12V, or an adjustable voltage.
Yes, it is available as an automotive grade product, but the adjustable output voltage option is only available in the TO-220FP package.
Only a 10 uF minimum capacitor is needed for stability.
