UA78M05CDCY Description

Short technical summary and product information.

The UA78M05CDCY from Texas Instruments is a fixed-voltage linear regulator designed for a wide range of applications. It provides a stable 5V output with a maximum current of 500mA. This device is suitable for on-card regulation to eliminate noise and distribution problems associated with single-point regulation.

 

Key electrical specifications include an input voltage range of 5.3V to 35V and a typical quiescent current of 4.5mA. The regulator incorporates internal current-limiting and thermal-shutdown features, protecting the device from overload conditions. It is designed to be stable without external components.

 

This component is available in a SOT-223-4 surface-mount package. The operating temperature range is specified from 0°C to 125°C. Applications include on-board charging, residential lighting, and battery backup units.
