US431AL

FEATURES SOT23-5 package 0.5% Voltage Reference Initial Accuracy (US431AL) Low Operational Cathode Current (80 uA max) Unconditionally Stable with only 1uF Adjustable Output from 1.24V to 6V 0.25Ω Typical Output Impedance Pin to Pin Compatible with TLV431 APPLICATIONS Precision Voltage Reference Linear Regulator Controller Secondary Side Controller for the Low Voltage Power Supply Applications US431L/431AL LOW -VOLTAGE ADJUSTABLE PRECISION SHUNT REGULATOR PRELIMINARY DATASHEET DESCRIPTION The US431L product is a 3 terminal adjustable shunt regulator that can also be used as a precision voltage reference. Its output voltage may be set to any value between Vref(1.24V) and 6V with two external resistors as shown in the typical application circuit. Other applications of this device include the use as a merged amplifier and reference in applications such as Linear regulator or as the secondary side controller in low voltage power supply applications. The US431L only requires 80uA maximum...
