The DS4303R is a non-volatile (NV), programmable voltage reference. The reference voltage can be set online during factory calibration/programming. Setting the reference voltage VOUT is as easy as loading the required voltage at VIN and triggering the adjustment pin (/ADJ) to lock the VOUT voltage indefinitely (even if the device is powered cyclically).
DS4303R Features
Accurate Electrically Regulated Voltage Reference
Automatic factory calibration for devices requiring voltage regulation
Adjustable over ±1mV range
Wide output voltage regulation range: adjustable to 300mV below supply voltage
Low temperature coefficient
±1mA output current drive
NV memory stores voltage indefinitely
Output short circuit protection
Low cost
Low power consumption
2.4V to 3.6V single supply operation
Small 5-pin SOT23 package
