SG1532/SG2532/SG3532

PRECISION GENERAL-PURPOSE REGULATOR

	DESCRIPTION	FEATURES
	This monolithic integrated circuit is a versatile, general-purpose voltage	∙	Input voltage range of 4.5V to 50V
	regulator designed as a substantially improved replacement for the popular	∙	2.5V low noise reference
	SG723 device. The SG1532 series regulators retain all the versatility of the	∙	Independent shutdown terminal
	SG723 but have the added benefits of operation with input voltages as low as	∙	Improved line and load regulation
	4.5 volts and as high as 50 volts; a low noise, low voltage reference;	∙	80mV current limit sense voltage
	temperature compensated, low threshold current limiting; and protective	∙	Fully protected including thermal
	circuits which include thermal shutdown and independent current limiting of	∙	shutdown
	both the reference and output voltages. A separate remote shutdown terminal		Useful output current to 150mA
	is included . In the dual-in-line package an open collector output is available	HIGH RELIABILITY FEATURES
	for low input-output differential applications.
	These devices are available in both hermetic 14-pin cerdip and 10-pin TO-		-SG1532
		♦ Available to MIL-STD-883
	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	♦ LMI level "S" processing available

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.

ELECTRICAL CHARACTERISTICS

(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG1532 with -55°C ≤ TA ≤ 125°C, SG2532 with

0°C ≤ TA ≤ 70°C, SG3532 with 0°C ≤ TA ≤ 70°C, V IN = 10V, VOUT = 5V, and IOUT = 1mA. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
