78L15 15V 100mA Integrated Circuit Positive 3 Terminal Voltage Regulator,
Description:
The 78L15 is a positive 3-terminal voltage regulators in a TO92 type package.
With adequate heat sinking these regulators can deliver 100mA output current. Current limiting is included to limit peak output current to safe value. Safe area protection for the output transistors is provided to limit internal power dissipation. If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown circuit takes over preventing the device from overheating.
When used as a zener diode/resistor combination replacement, these devices usually result in an effective output impedance improvement of two orders of magnitude, and lower quiescent current. These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regulation. Typical applications include use in logic systems, instrumentation,HiFi, and other solid state electronic equipment.
Although designed primarily as fixed voltage regulators these devices can be used with external components to obtain adjustment voltages and currents.
