Product Introduction

Overview

The LD1086DT15R, produced by STMicroelectronics, is a low drop voltage regulator designed to provide up to 1.5 A of output current. This regulator is characterized by its high efficiency and low dropout voltage, making it suitable for a wide range of applications. The LD1086DT15R is pin-to-pin compatible with older 3-terminal adjustable regulators but offers improved performance in terms of dropout and output tolerance. It is available in various packages, including TO-220, D²PAK, D²PAK/A, DPAK, and DFN8 (4x4 mm), ensuring flexibility in design and implementation.
