DESCRIPTION
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.

1) All characteristics are measured with a capacitor across the input of 2.2µF and a capacitor across the output of 1.0µF.
All characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (tp ≤ 10ms, δ ≤ 5%). Output
voltage changes due to changes in internal temperature must be taken into account separately.
2) Test Conditions unless otherwise stated:PMAX = 10W for SMD , PMAX = 20W for all other package devices
