REF19x series precision bandgap voltage references use a pat-ented 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 lessthan 45 m A 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 lessthan 15 m A.

The REF19x series references are specified over the extended industrial temperature range (40 C to +85 C) with typical performance specifications over 40 C to +125 C for applica- tions such as automotive.

All electrical grades of REF19x are available in 8-Lead SOIC; the PDIP and TSSOP are only available in the lowest electrical grade. Prod-ucts are also available in die form.
