Ordering Information
The 78L05 is a 5V fixed 3-terminal voltage regulator
delivering up to 100mA of output current and equipped
with internal limiting + thermal shutdown features for
overload immunity. Implementing this device at point-
of-source removes the complexity of single point
regulation methods with reduced noise. Used in
replacement of a Zener diode/resistor combination, the
device improves output impedance by x2 order of
magnitude and delivers lower bias current with lower
noise. The 78L05 can also be used with power-pass
elements to make high-current voltage regulators.
