Texas Instruments UA78M05CDCYR 5V 500mA Linear Voltage Regulator SOT-223-4

Texas Instruments UA78M05CDCYR is a fixed 5V linear voltage regulator with up to 500mA output current, designed to provide stable, regulated power for a range of electronic applications, including sensitive digital logic and microcontroller circuits.

Key Features

• Fixed 5V output with up to 500mA output current
• Wide input voltage range from 7V to 25V
• On-card regulation, which helps reduce noise and distribution problems commonly associated with single-point regulation in larger systems
• Internal current-limiting, thermal-overload protection and output transistor safe-area compensation
• No external components required for basic operation, which simplifies design and reduces the bill of materials and board space
• Operating temperature range from 0°C to 125°C

Overview

The regulator can also be used with external components to create adjustable output voltages and currents, or act as the power-pass element within a more precise regulator circuit. Its internal protection features provide resilience against overloads, short-circuits and high-power dissipation scenarios.

Package and Specifications

Supplied in a compact, surface-mount SOT-223-4 package, the device is suitable for space-constrained portable and embedded designs. Dimensions are 3.3 (width) x 1.5 (depth) x 4.3 (height), with a weight of 4.536 g.

Environmental Information

This is a green product manufactured without antimony or brominated flame retardants (Sb/Br), aligning with modern environmental standards.

Applications

Common applications include power management subsystems, portable and battery-powered devices, desktop computers and servers, computer peripherals, and communications and networking equipment. The UA78M05CDCYR is a suitable choice when a stable 5V supply is required from an input in the 7V to 25V range.
