HM78L05
Description
The HM78LXX is a fixed voltage (3V/3.3V/5V) threeterminal integrated regulator that can be used in many applications. Its excellent internal current limit and thermal shutdown characteristics make it especially suitable for overload conditions. When used to replace the traditional Zener diode-resistor bank, its output impedance is effectively improved, but the bias current is greatly reduced.
With enough heat dissipation, HM78LXX can provide 100m A output current. A current limit is included to limit the peak output current to a safe value, and a safe area protection for the output transistor to limit internal power dissipation. A thermal shutdown circuit prevents the IC from overheating if the internal power dissipation is too high for the provided heat sink.
