UC2835D

The Texas Instruments UC2835D is a linear regulator controller optimized for low-cost, low-dropout linear regulator designs. It features a fixed 5V output voltage and can also be configured for adjustable output from 2.5V to 35V using external resistors. The device includes accurate 2.5A current limiting with foldback, providing protection against overcurrent conditions.

Key features include internal current sense, remote sense capability for improved load regulation, and external shutdown functionality. It also incorporates under-voltage lockout and reverse voltage protection for predictable start-up and protection against negative input-to-output differentials. Thermal shutdown protection is integrated to safeguard the device.

This controller is available in an 8-SOIC surface mount package, suitable for various electronic designs. The operating temperature range is -25°C to 85°C, making it suitable for a wide range of applications. The UC2835D requires an external pass element to achieve low dropout voltages of less than 0.5V.

Applications for this linear regulator controller include power supplies, battery chargers, and other power management systems where efficient and stable voltage regulation is required. Its robust protection features and flexible output voltage options make it a versatile component for embedded systems and industrial controls.
