V-Ref Precision 4.5V 30mA 8-Pin PDIP Tube

The REF19x series precision band gap 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 high initial accuracy. The REF19x series is made up of micro power, low dropout voltage (LDV) devices, providing stable output voltage from supplies as low as 100 mV above the output voltage and consuming less than 45 uA of supply current. In sleep mode, which is enabled by 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 uA. The REF19x series references are specified over the extended industrial temperature range (-40oC to +85oC) with typical performance specifications over -40oC to +125oC for applications, such as automotive. All electrical grades are available in an 8-lead SOIC package; the PDIP and TS SOP packages are available only in the lowest electrical grade. Products are also available in die form.
