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)

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.

Fixed Output Regulator
* Required if the regulator is located far from
the power supply.
** Although no output capacitor is needed for
stability, it does help transient response.(If
needed, use 0.1mF ceramic disc)
