Microsemi JAN723J Precision voltage regulator Datasheet

SG723
PRECISION VOLTAGE REGULATOR
DESCRIPTION
FEATURES
This monolithic voltage regulator is designed for use with either positive
or negative supplies as a series, shunt, switching, or floating regulator
with currents up to 150mA. Higher current requirements may be
accommodated through the use of external NPN or PNP power
transistors. This device consists of a temperature compensated
reference amplifier, error amplifier, power series pass transistor, current
limit, and remote shutdown circuitry.

ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply for the operating ambient temperature of TA = 25°C, VIN = VC = 12V, V- = 0V, VOUT = 5V, IL =
1 mA, RSC = 0Ω, C1 = 100pF, and divider impedance as seen by error amplifier ≤ 10KΩ. Low duty cycle pulse testing echniques are used which maintains
junction and case temperatures equeal to the ambient temperature.)
