78L05 voltage regulator

 

Description

The 78L05 is a voltage regulator integrated circuit (IC) commonly used in electronics projects. It is a type of voltage regulator that provides a constant voltage output of 5 volts and is commonly used to power small electronic devices, such as microcontrollers, sensors, and displays

The 78L05 series of three-terminal positive regulators employ internal current limiting and hermal shutdown, making them essentially ndestructible. If adequate heat-sink is provided, they can deliver up to 100 mA output current. They are intended as fixed voltage regulators in a wide range of applications including local or on card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power pass elements to make high-current voltage regulators. The voltage regulator series used as Zener diode/resistor combination replacement, offers e improvement along with lower quiescent current and lower noise.

Features

1. Output current up to 100 mA

2. Output voltages of 5V thermal overload protection

3. Short-circuit protection

4. No external components are required

5. Available in either ± 4% (A) or ± 8% (C)  selection

A voltage regulator is an electronic device that is used to maintain a constant voltage level, regardless of changes in load or input voltage. It does this by adjusting the output voltage so that it remains within a specified range.
This helps to ensure that the voltage supplied to a device remains within the acceptable range, even under varying conditions such as changes in temperature or load.
