DESCRIPTION
AMC78L05
100mA / 3-T
ERMINAL
5V R
EGULATOR
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 provide local on card regulation,
eliminating the distribution problems associated with
single point regulation. In addition, it can be used with
power-pass elements to make high-current voltage
regulators with 100mA output current.
Protection features such as thermal shutdown and current
limiting have been designed internally which will protect
the device from damage in case of overload or
overheating.
APPLICATIONS
±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.

number (i.e. AMC78L05LPT, AMC78L05DMT or AMC78L05PKT).
2. For TO-92 in Tape & Box (without reel), add suffix “TB” (i.e. AMC78L05LPTB)
3. The letter “F” is marked for Lead Free process .
