Details

The L78 series of three-terminal positive regulators is available in TO-220, TO-220FP, D²PAK and DPAK packages and several fixed output voltages, making it useful in a wide range of applications.These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type embeds internal current limiting, thermal shut down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.Features● Output current up to 1.5 A● Output voltages of 5; 6; 8; 8.5; 9; 12; 15; 18; 24 V● Thermal overload protection● Short circuit protection● Output transition SOA protection● 2 % output voltage tolerance (A version)● Guaranteed in extended temperature range (A version)

FAQs

What is L7805CDT-TR?

The L7805CDT-TR is a linear voltage regulator integrated circuit (IC) manufactured by STMicroelectronics. It is a 3-terminal device that provides a fixed 5V output voltage from a higher input voltage source. The regulator is commonly used in various electronic circuits to stabilize and regulate the power supply voltage.

How Does L7805CDT-TR Work?

The L7805CDT-TR operates by comparing the output voltage to a stable reference voltage and adjusting the pass device to maintain the desired output voltage. It regulates the output voltage by dissipating excess energy as heat. The IC can handle a maximum input voltage range and provides a constant 5V output voltage under different load conditions.

How Many Pins does L7805CDT-TR have and What are the Functions of the Pinout Configuration?

The L7805CDT-TR is available in a TO-252 package with 3 pins. The pinout configuration includes:

  • Input (Vin): The input pin connected to the higher voltage supply.
  • Ground (GND): The ground pin for the regulator.
  • Output (Vout): The regulated 5V output pin.

What are the Pros and Cons of L7805CDT-TR?

Pros:

  • Simple to Use: Easy to implement in various circuits for voltage regulation.
  • Fixed Output Voltage: Provides a stable 5V output, eliminating the need for additional voltage regulation components.
  • Low Cost: Economical solution for basic voltage regulation needs.
  • Widely Available: Produced by multiple manufacturers and readily available in the market.

Cons:

  • Heat Dissipation: May require a heat sink for higher current applications due to heat generation.
  • Dropout Voltage: Requires a minimum input-output voltage differential for proper regulation.
  • Limited Current: Has a maximum current rating that may not suit high-power applications.

Are There Any Equivalents/Alternatives to L7805CDT-TR for Recommendation?

  • The LM7805 from Texas Instruments is a direct equivalent to the L7805CDT-TR.
  • Alternatives to the L7805CDT-TR include the MC7805 from ON Semiconductor and the UA7805 from Fairchild Semiconductor.
