L78L05CZ

The L78L05CZ is a three-terminal positive Voltage Regulator designed to deliver a regulated output voltage of 5V and can deliver up to 100mA of output current. It has features such as on-chip Thermal Shutdown, Short-circuit Current Limiting and Output Transistor Safe Operating Area protection. It is available in the five-pin TO92 package, making it suitable for a wide range of applications.

The L78L05CZ belongs to the category of Linear Voltage Regulators, and is one of the most popular single-cell regulators widely used in mobile phones, audio systems, STBs and other consumer electronics. It is widely used due to its wide input voltage range, low noise and low output current ripple. It is available in fixed output voltage versions of 5V, 9V and 12V, making it suitable for different applications.

This Voltage Regulator is a three-terminal device, comprising of an input terminal, an output terminal and a ground terminal. The input terminal is connected to the DC Voltage source, such as a battery, and the output terminal is connected to the output load, such as a microcontroller. The ground terminal should be connected to a ground reference, usually the 0V of the power supply.

The working principle of the L78L05CZ is based on the Adjustable Voltage Regulator principle. The Adjustable Voltage Regulator is essentially an on-chip internal reference voltage source, combined with an error amplifier, which is used to control the output voltage. This reference voltage source is coupled with a voltage divider network, which produces a voltage proportional to the required output voltage, which is then compared to the actual output voltage. Depending on the difference between the two, the error amplifier then provides an output current which compensates for the difference, thereby delivering a regulated output voltage.

The L78L05CZ is specially designed to provide a regulated output voltage of 5V, and works very well when the input voltage is higher than the output voltage. It is capable of delivering a maximum of 100mA of output current. It is designed with on-chip Thermal Shutdown, Short-circuit Current Limiting and Output Transistor Safe Operating Area protection. It is available in the five-pin TO92 package, making it suitable for a wide range of applications.

The L78L05CZ is a widely used Voltage Regulator, suitable for a wide range of applications such as mobile phones, audio systems, STBs and other consumer electronics.
