The ADR421BRZ-REEL is an adjustable Low-Dropout (LDO) voltage reference IC made by Analog Devices and supplied in an 8-pin SOIC-8 RoHS (Lead Free) package. This precision voltage reference features a wide operating voltage range of 5.7 V to 40 V, a reference voltage of 2.5V, and a stabilized, extremely low quiescent current of 2 uA. The output voltage is adjustable from 0V to 2.5 V via an external resistor divider, and the distinctively low offset and low temperature drift offer exceptional performance even in extreme conditions. This part is well-suited for precision analogue and digital control applications such as LED drivers, power management circuits, operational amplifiers, data converters, and voltage-regulated power supplies.
