SG140A/SG140

POSITIVE FIXED VOLTAGE REGULATOR

DESCRIPTION

FEATURES

The SG140A/140 series of positive regulators offer self contained, fixed-voltage

capability with up to 1.5A of load current and input voltage up to 50V (SG140A series

only).

• Output voltage set internally to

1.5% on SG140A

• Input voltage reange to 50V max.

on SG140A

These units feature a unique on-chip trimming system to set the output voltages to

within 1.5% of nominal on the SG140A series and 2.0% on the SG140 series. The

SG140A versions also offer much improved line and load regulation characteristics.

Utilizing an improved Bandgap reference design, problems have been eliminated that

arenormallyassociatedwiththeZenerDiodereferences, suchasdriftinoutputvoltage

and large changes in the line and load regulation.

• Two volt input-output differential

• Bandgap reference voltage

• Excellent line and load regulation

• Foldback current limiting

• Thermal overload protection

• Voltages available - 5V, 12V, 15V

• Voltages Not Recommended For

New Designs - 6V, 8V, 18V, 24V

Allprotectivefeaturesofthermalshutdown,currentlimiting,andsafe-areacontrolhave

been designed into these units and since these regulators require only a small output

capacitor for satisfactory performance, ease of application is assured.

HIGH RELIABILITY FEATURES

- SG140A/140

Although designed as fixed-voltage regulators, the output voltage can be increased

through the use of a simple voltage divider. The low quiescent drain current of the

device insures good regulation when this method is used.

♦ Available to MIL-STD - 883

♦ Radiation data available

♦ LMI level "S" processing available

Product is available in hermetically sealed TO-257 (isolated), TO-3, TO-66, and

TO-39 power packages.
