ONSEMI MC78L05ABDR2G 5V 100mA Positive Voltage Regulator, SOIC-8

The ONSEMI MC78L05ABDR2G is a fixed output, positive linear voltage regulator presented in a compact 8-pin SOIC surface-mount package. This cost-effective and easy-to-use device is engineered to deliver a stable 5V output from an input voltage range of 10V to 30V, with a maximum output current of 100mA. It is an ideal solution for a multitude of applications requiring a simple, reliable, and regulated power supply.

Engineered for robustness, this regulator incorporates key protection features including internal short-circuit current limiting and thermal shutdown. These mechanisms safeguard the device against overload conditions and excessive heat, making it remarkably rugged for continuous operation. A significant advantage over traditional zener diode-resistor combinations is its substantially reduced output impedance and quiescent current, leading to improved efficiency and performance.
