The IP120 / LM120 / IP7900 / LM7900 series of 3 terminal
regulators is available with several fixed output voltage
making them useful in a wide range of applications.
The ‘A’ suffix devices provide 0.7% / V line regulation,
0.5% / A load regulation and ±1.0% output voltage tolerance
at room temperature.
Protection features include Safe Operating Area current
limiting and thermal shutdown.
