AMC78L05
100mA / 3-TERMINAL 5V
REGULATOR
DESCRIPTION FEATURES
The AMC78L05 is a 3-terminal positive regulator with
a fixed output voltage of 5V. Although it is designed as a
fixed-voltage regulator, the output voltage can be increased
by the use of a simple voltage divider. This regulator can
p
rovide local on card regulation, eliminating the distribution
p
roblems associated with single point reg u lation. In ad d ition,
it can be used with power-
p
ass elements to make
high-current voltage regul ators with 100mA output current .
Protection features such as thermal shutdown and
current limiting have been designed internally which will
p
rotect the device from damage in case of overload or
overheating.
±5% tolerance of output voltage
Wide input range
Output current > 100mA
Internal thermal overload protection
No External Components
Short circuit protection
Available in 3L plastic TO-92, surface mount
SOT-89 and plastic 8 pin S.O.I.C.
Identical pin assignment to earlier 78L05 series.
