REF19x series precision bandgap voltage references use a patented temperature drift curvature correction circuit and laser trimming of highly stable thin film resistors to achieve a very low temperature coefficient and a high initial accuracy.
The REF19x series are micropower, Low Dropout Voltage (LDV) devices providing a stable output voltage from supplies as low as 100 mV above the output voltage and consuming less than 45 µA of supply current.In sleep mode, which is enabledby applying a low TTL or CMOS level to the sleep pin, the output is turned off and supply current is further reduced to less than 15 µA.
The REF19x series references are specified over the extended industrial temperature range (–40°C to +85°C) with typicalperformance specifications over –40°C to +125°C for applica-tions such as automotive.All electrical grades are available in 8-Lead SOIC; the PDIP and TSSOP are only available in the lowest electrical grade. Products are also available in die form.
