 SG3532
SG1532/SG2532/SG3532
PRECISION GENERAL-PURPOSE REGULATOR
DESCRIPTION
This monolithic integrated circuit is a versatile, general-purpose voltage
regulator designed as a substantially improved replacement for the popular
SG723 device. The SG1532 series regulators retain all the versatility of the
SG723 but have the added benefits of operation with input voltages as low as
4.5 volts and as high as 50 volts; a low noise, low voltage reference;
temperature compensated, low threshold current limiting; and protective
circuits which include thermal shutdown and independent current limiting of
both the reference and output voltages. A separate remote shutdown terminal
is included . In the dual-in-line package an open collector output is available
for low input-output differential applications.
These devices are available in both hermetic 14-pin cerdip and 10-pin TO-
96 packages. In the T-package, these units are interchangeable with the LAS-
1000 and LAS-1100 regulators. The SG1532 is rated for operation over the
ambient temperature range of -55°C to 125°C while the SG2532 and SG3532
are intended for industrial applications of 0°C to 70°C.
FEATURES
Input voltage range of 4.5V to 50V
2.5V low noise reference
Independent shutdown terminal
Improved line and load regulation
80mV current limit sense voltage
Fully protected including thermal
shutdown
Useful output current to 150mA
HIGH RELIABILITY FEATURES
-SG1532
Available to MIL-STD-883
