MC79L15ACPRAG Datasheet PDF - ON Semiconductor

The MC79L15ACPRAG is a low cost, low current negative fixed linear voltage regulator in 3 pin TO-92 package. This inexpensive and easy to use negative voltage regulator is suitable for numerous applications requiring up to 100mA output current. Like the higher powered MC7900 series negative regulators, this device features thermal shutdown and current limiting, making it remarkably rugged. The thermal overload protections shuts down the circuit when subjected to an excessive power overload condition and internal short circuit protection limits the maximum current the circuit will pass. In most applications, no external components are required for operation. The MC79L15A device is useful for on-card regulation or any other application where a regulated negative voltage at a modest current level is needed. This regulator offers substantial advantage over the common resistor/zener diode approach.
