BIPOLAR ANALOG INTEGRATED CIRCUIT
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
