DESCRIPTION

The IP140A / LM140 / IP7800A / IP7800 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 are fully specified at 1A, 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.

ABSOLUTE MAXIMUM RATINGS (Tcase = 25°C unless otherwise stated)

VI	DC Input Voltage	(for VO = 5, 12, 15V)	35V
PD	Power Dissipation		Internally limited 1
Tj	Operating Junction Temperature Range		–55 to 150°C
Tstg	Storage Temperature		–65 to 150°C

Note 1. Although power dissipation is internally limited, these specifications are applicable for maximum power dissipation PMAX of 20W. IMAX = 1.0A.

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

2) Although power dissipation is internally limited, these specifications are applicable for maximum power dissipation PMAX of 20W ,

IMAX = 1.0A.
3) TJ = 25°C unless otherwise stated.
