Linear & Switching Voltage Regulators

UCC284SDR-5EP Description

The UCC284SDR-5EP is a linear voltage regulator designed by Texas Instruments, featuring a fixed output voltage of -5V and a maximum output current of 500mA. This regulator is housed in an 8-pin SOIC package, making it suitable for surface-mount applications. Despite being marked as obsolete, the UCC284SDR-5EP remains a reliable choice for applications requiring a negative output configuration. It offers a low dropout voltage of 0.5V at 500mA, ensuring efficient power regulation even under varying load conditions. The regulator also includes essential protection features such as over-temperature protection, short-circuit protection, and under-voltage lockout (UVLO), enhancing its reliability and durability in demanding environments.

UCC284SDR-5EP Features

• Output Type: Fixed at -5V, providing a stable and consistent voltage supply.
• Output Current: Capable of delivering up to 500mA, suitable for a wide range of low to medium power applications.
• Low Dropout Voltage: A maximum dropout voltage of 0.5V at 500mA ensures efficient power regulation and minimal power loss.
• Protection Features: Over-temperature protection, short-circuit protection, and under-voltage lockout (UVLO) safeguard the regulator and connected components from damage.
• Control Features: An enable feature allows for dynamic control of the regulator's operation, enhancing flexibility in system design.
• Low Quiescent Current: A quiescent current of 250 µA minimizes power consumption during standby or low-load conditions.
• Compliance: The UCC284SDR-5EP is REACH unaffected and ROHS3 compliant, ensuring it meets environmental and regulatory standards.
• Moisture Sensitivity Level: MSL 2 (1 Year) indicates that the component is suitable for standard manufacturing processes without requiring special handling for moisture sensitivity.
