LM79XX/A (KA79XX, MC79XX) FIXED VOLTAGE REGULATOR (NEGATIVE)
3-TERMINAL 1A NEGATIVE VOLTAGE REGULATORS
The LM79XX series of three-terminal negative regulators are available in
TO-220 package and with several fixed output voltages, making them useful
in a wide range of applications. Each type employs internal current limiting,
thermal shut-down and safe area protection, making it essentially indestructible.
FEATURES
• Output Current in Excess of 1A
• Output Voltages of -5, -6, -8, -12, -15, -18, -24V
• Internal Thermal Overload Protection
• Short Circuit Protection
• Output Transistor Safe-Area Compensation

Notes:
(1) To specify an output voltage, substitute voltage value
for “XX “
(2) Required for stability. For value given, capacitor
must be solid tantalum. If aluminum electronics are
used, at least ten times value shown should be
selected. C
I
is required if regulator is located an
appreciable
distance from power supply filter.
(3) To improve transient response. If large capacitors
are used, a high current diode from input to output
(1N400l or similar) should be introduced to protect
the device from momentary input short circuit.
*: Against potential latch-up problems.

1. Life support devices or systems are devices or
systems which, (a) are intended for surgical implant into
the body, or (b) support or sustain life, or (c) whose
failure to perform when properly used in accordance
with instructions for use provided in the labeling, can be
reasonably expected to result in significant injury to the
user.
2. A critical component is any component of a life
support device or system whose failure to perform can
be reasonably expected to cause the failure of the life
support device or system, or to affect its safety or
effectiveness.
