This document provides information on a product in full production, named LD1086xx, which is a low dropout positive voltage regulator. It can provide adjustable or fixed output voltage and has features such as low dropout, wide operating temperature range, and high output current up to 1.5A. It is suitable for automotive applications.
The LD1086xx is a low dropout positive voltage regulator capable of providing up to 1.5 A of output current. It features a typical dropout of 1.3 V at 1.5 A and offers both adjustable and fixed output voltage options, including 1.8V, 2.5V, 3.3V, 5V, and 12V. The device is pin-to-pin compatible with standard adjustable voltage regulators but provides better performance in terms of dropout and output tolerance.
The regulator is available in automotive grade for adjustable output voltages in TO-220 and DPAK packages, qualified according to the AEC-Q100 specification. It operates over a wide temperature range of -40 °C to 125 °C and is available in TO-220, DPAK, DPAK/A, and DFN8 (4x4 mm) packages. Only a 10 µF minimum capacitor is required for stability.
