Texas Instruments UA78M05CDCY 5V 500mA Linear Voltage Regulator, SOT-223

The Texas Instruments UA78M05CDCY is a high-performance, fixed 5V positive linear voltage regulator in a compact SOT-223 surface-mount package. Designed to deliver a stable 5V output from an input voltage range of 7V to 25V, this reliable component is engineered to supply up to 500mA of continuous output current, making it an ideal choice for a wide array of electronic designs.

This 3-terminal regulator simplifies circuit design by requiring no external components for basic operation, saving valuable board space and reducing overall system cost. Its robust internal protection features, including thermal-overload shutdown and internal short-circuit current limiting, make the device essentially immune to overload conditions, enhancing the durability and safety of your application. The output transistor also includes safe-area compensation for added reliability.

A key advantage is that an output capacitor is not required for stability, further simplifying the bill of materials. As a 'green' product, it is manufactured with no antimony or brominated flame retardants (no Sb/Br), aligning with modern environmental standards for electronic components.

Primary Applications

This versatile regulator is perfect for on-card regulation, effectively eliminating noise and distribution problems associated with single-point power supplies. Its capabilities extend beyond a simple fixed regulator; with external components, it can be configured for adjustable output voltages and currents or used as the power-pass element in a precision regulator circuit.

Ideal For:

• Portable and battery-powered devices
• Computer systems and peripherals
• Communications and networking equipment
• General-purpose power supply regulation on PCBs

With an operating temperature range of 0°C to 125°C, the UA78M05CDCY offers high power-dissipation capability in a small footprint, ensuring reliable,
