FAQs

What is UA78M05CDCY?

The UA78M05CDCY is a 500mA fixed positive voltage regulator manufactured by Texas Instruments. It is part of the 78xx series of fixed linear voltage regulators and is designed to provide a stable 5V output voltage from a higher input voltage source. This device is commonly used in various electronic circuits and applications that require a reliable and regulated 5V power supply.

How Does UA78M05CDCY Work?

The UA78M05CDCY works by taking an input voltage, which can range from around 7V to 25V, and regulating it down to a steady 5V output. It does this by using a pass transistor and a voltage reference to compare the output voltage to a stable internal reference. Any fluctuations in the output voltage are adjusted by the regulator to maintain a constant 5V output.

How Many Pins does UA78M05CDCY have and What are the Functions of the Pinout Configuration?

The UA78M05CDCY is housed in a 3-pin TO-252 or DPAK (power plastic) package. The pinout configuration includes:

  • Input (Vin): This is the input pin for the higher voltage source, typically around 7V to 25V.
  • Ground (GND): The ground pin is the reference point for the regulator and the load connected to the output.
  • Output (Vout): This pin provides the regulated 5V output voltage that the device is designed to deliver.

What are the Pros and Cons of UA78M05CDCY?

Pros:

  • Stable Voltage Output: Provides a reliable and stable 5V output voltage.
  • Wide Input Voltage Range: Can handle input voltages from around 7V to 25V, making it versatile for various applications.
  • Overcurrent Protection: Includes built-in overcurrent protection to safeguard the connected circuitry.
  • Simple to Use: Easy to connect and implement in electronic circuits requiring a 5V regulated power supply.

Cons:

  • Heat Dissipation: May require a heat sink if the regulator needs to dissipate significant power.
  • Power Dissipation: In high input voltage to low output voltage conditions, the regulator may dissipate significant power as heat.

Are There Any Equivalents/Alternatives to UA78M05CDCY for Recommendation?

  • The LM7805 from Texas Instruments and the L78S05CV from STMicroelectronics are equivalent alternatives to the UA78M05CDCY.
  • Alternatives to the UA78M05CDCY include the NCV7805 from ON Semiconductor and the KA7805 from Fairchild Semiconductor.
