The 78L09 Positive Voltage Regulator in a TO-92 package is a versatile and reliable integrated circuit designed for a wide range of applications. This fixed-voltage regulator offers a consistent output of +9V, making it ideal for on-card regulation, eliminating noise and distribution problems associated with single-point regulation. It can also be used with power-pass elements to create high-current voltage regulators, delivering up to 100mA of output current.
One of the standout features of the 78L09 is its internal limiting and thermal-shutdown capabilities, which make it essentially immune to overload. When used as a replacement for a zener diode-resistor combination, it provides an effective improvement in output impedance along with lower bias current.
