STMicroelectronics LD1085xx User Manual
The LD1085xx is a low‑dropout positive voltage regulator capable of delivering up to 3 A of output current. It offers adjustable or fixed output voltages (1.5 V, 1.8 V, 2.5 V, 3.3 V, 5 V, 12 V) with a typical dropout of 1.3 V at full load and tight output tolerance (+1 % at 25 °C, +2 % over the full temperature range). The device is available in several TO‑220 and DPAK style packages and includes internal power and thermal limiting.
The manual contains a diagram, pin configuration, maximum ratings, schematic application, electrical characteristics, typical application circuit, mechanical data, order codes, and revision history. It also includes safety and warranty notices specific to ST products.
