Linear & Switching Voltage Regulators

LD1085D2M-R Description

The LD1085D2M-R from STMicroelectronics is a high-performance, adjustable positive linear voltage regulator designed to deliver up to 3A of continuous output current with an input voltage range of up to 30V. This surface-mount device (D2PAK-3 package) offers a highly stable output voltage adjustable from 1.25V to 28.5V, making it versatile for a wide range of power supply applications. With a low dropout voltage of 1.5V at 3A, it ensures efficient operation even under high load conditions. The regulator features 72dB PSRR (120Hz), minimizing noise and ripple for clean power delivery. Its 10mA quiescent current and robust protection mechanisms, including over-current and over-temperature safeguards, enhance reliability in demanding environments.
