Some of the text within the PDF file :

The 78L05 is a three-terminal device with an input pin (Vin), an output pin (Vout), and a common ground pin (GND). It is typically housed in a small TO-92 package. The input voltage supplied to the Vin pin should be higher than the desired output voltage by a certain margin to allow for proper regulation. The regulator operates by maintaining a constant voltage drop across it, regardless of changes in the input voltage or load current.

 

The maximum input voltage that the 78L05 can handle depends on the specific variant, but it is generally around 30 volts. It can provide a maximum output current of about 100 mA, although this may vary depending on the manufacturer and package variant.

 

The 78L05 is widely used in various electronic circuits to provide a stable and regulated +5V power supply. It is commonly employed to power low-power microcontrollers, digital logic circuits, sensors, and other components that require a reliable voltage source. By using the 7805, fluctuations and variations in the input voltage are minimized, ensuring that the connected components receive a consistent and accurate supply voltage.
