The 78L05 is a widely used voltage regulator integrated circuit (IC) that provides a fixed, regulated output voltage of +5 volts. It is part of the 78xx series of voltage regulators, where xx represents the specific output voltage. In the case of the 78L05, it regulates the output voltage to +5 volts.
Here are some key characteristics and specifications of the 78L05 voltage regulator:
Type: 78L05 is a positive voltage regulator IC, which means it provides a stable and regulated positive output voltage.
Package: The 78L05 is available in various packages, including TO-92, SOT-89, and other surface-mount packages, depending on the manufacturer and application.
Output Voltage: The 78L05 provides a fixed output voltage of +5 volts, which is commonly used to power various electronic components, especially in low-power applications.
Maximum Output Current: The maximum output current (Iout) of the 78L05 varies with different manufacturers and packages but is typically around 100 mA to 1000 mA (1A). This means it can supply current in the range of 100 milliamperes to 1 ampere, depending on the specific part number and package.
Input Voltage Range: The input voltage (Vin) should be higher than the desired output voltage by some margin to allow for proper regulation. For the 78L05, this margin is typically around 2 volts. So, for a +5V output, you would need an input voltage of around +7V to +12V, depending on the specific manufacturer and package.
Regulation: The 78L05 provides excellent voltage regulation, maintaining a stable +5V output voltage even when the input voltage varies over a specified range.
Applications: The 78L05 is used in various low-power applications to provide a stable +5V supply, such as powering microcontrollers, sensors, and other digital and analog electronic components.
Pin Configuration: The 78L05 typically has three pins: input (Vin), ground (GND), and output (Vout). The pinout can vary depending on the package and manufacturer.
