FEATURES
The AMC79L05 is a 3-terminal fixed negative-voltage
designed for a wide range of applications.
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
Internal thermal overload protection
Output current > 100mA
No External Components
Short circuit protection
Available in 3L plastic TO-92 and
plastic 8 pin S.O.I.C.
Identical pin assignment to earlier
79L05 series.

Note:
1.All surface-mount and TO-92 packages are available in Tape & Reel. Append the letter “T” to part
number (i.e. AMC79L05LPT or AMC79L05DMT).
2.For TO-92 in Tape & Box (without reel), add suffix “TB” (i.e. AMC79L05LPTB).
3.The letter ”F” is marked for Lead Free process.
