PC79M00 Series
THREE TERMINAL NEGATIVE VOLTAGE REGULATOR
µ
PC79M00 series are monolithic three terminal negative regulators which employ internally current limiting, ther-
mal shut down, output transistor safe operating area protection make them essentially indestructible.
They are intended as fixed voltage regulators in a wide range of application including local on card regulation for
elimination of distribution problems associated wide single point regulation.
FEATURES
• Output current out of 500 mA.
• On-chip some protection circuit (over current protection, SOA protection and thermal shut down).
• Low noise.
