About this manual

The KD1084 is a low drop positive voltage regulator capable of providing up to 5 A of output current. It is available in both adjustable and fixed output voltage versions (1.8 V, 3.3 V, and 2.85 V). The device is pin-to-pin compatible with standard adjustable regulators but offers improved performance regarding dropout voltage and output tolerance.

The regulator is supplied in DPAK and D2PAK packages and features a wide operating temperature range from -40 °C to 125 °C. It includes internal power and thermal limiting, and its quiescent current flows into the load, increasing efficiency compared to PNP regulators. Only a 10 µF minimum capacitor is required for stability.
