μ
PC79Mxx Series
THREE TERMINAL NEGATIVE VOLTAGE REGULATOR
<R>
DESCRIPTION
The
μ
PC79Mxx Series are three-terminal negative output voltage stabilization power supply circuit of fixed output
voltage. It regulates non-stabilized DC input voltage to output stabilized fixed voltage.
The six types of voltage value are
−5
V,
−8
V,
−12
V,
−15
V,
−18
V and
−24
V, and they can be respectively used as
power supply circuit with maximum current capacity 500 mA.
FEATURES
•
Output current : 500 mA
•
On-chip some protection circuits
(over current protection, SOA protection and thermal shut down)
•
Low noise

Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge
of suffering physical damage, and therefore the product must be used under conditions that ensure that
the absolute maximum ratings are not exceeded.
