DESCRIPTION
The IP120A / LM120 / IP7900A / IP7900 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 0.01% / V line regulation,
0.3% / A load regulation and ±1% output voltage tolerance at
room temperature.
Protection features include Safe Operating Area current
limiting and thermal shutdown.

1) All characteristics are measured with a capacitor across the input of 0.22mF and a capacitor across the output of 0.1mF.
All characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (t

10ms, d£5%). Output
voltage changes due to changes in internal temperature must be taken into account separately.
