Good input stability.
Space-saving packages -
TO-92
or
SOT-89
DESCRIPTION
The SS6714 is a series of 3-terminal negative
voltage regulators with output voltages internally
set below the positive supply voltage. Since the
SS6714 consumes less current and requires
a smaller input/output voltage difference than
existing
industry-standard
3-terminal
voltage
regulators, higher capacity and longer service life
can be provide in battery-powered portable
equipment. The SS6714 is ideal as a power
source for liquid crystal displays.

APPLICATION INFORMATION
A capacitor of at least 1µF is required between the
output of the SS6714 and ground for stability.
Without this capacitor the part will oscillate. Even
though most types of capacitor may work, the
equivalent series resistance (ESR) should be held
to 5
Ω
or less if an aluminum electrolytic type is
used. Many aluminum electrolytic capacitors have
electrolytes that freeze at about -30°C, so solid
tantalum capacitors are recommended for operation
below -25°C. The value of this capacitor may be
increased without limit.
A capacitor of at least 0.1µF should be placed from
the input of the SS6714 to ground if the lead
inductance between the input and power source
exceeds 500nH (approximately 10 inches of trace).
