The LD1086 is a low dropout voltage regulator that can provide up to 1.5A of output current. It has adjustable or fixed output voltage options, including 1.5V, 1.8V, 2.5V, 2.85V, 3.3V, 3.6V, 5V, 8V, 9V, and 12V. The output tolerance is ±1% at 25°C and ±2% over the full temperature range. It features internal power and thermal limit, and operates in a wide temperature range from -40°C to 125°C. The LD1086 is available in TO-220, D2PAK, D2PAK/A, and DPAK packages. It is pin-to-pin compatible with older 3-terminal adjustable regulators but offers better performance in terms of dropout and output tolerance. The LD1086 has a quiescent current that flows into the load, increasing efficiency. Only a minimum 10µF capacitor is required for stability. The document also provides order codes for different models and packages.
The LD1086 is a low‑dropout voltage regulator capable of delivering up to 1.5 A of output current. It offers both adjustable and fixed output versions (1.5 V to 12 V) and is pin‑compatible with older three‑terminal regulators, while delivering lower dropout and tighter voltage tolerance.
The device is supplied in TO‑220, D2PAK, D2PAK/A and DPAK packages. Electrical characteristics such as dropout voltage, line and load regulation, quiescent current and short‑circuit capability are detailed in the datasheet, along with mechanical dimensions and revision history.
