REF196GSZ-REEL7

参考电压 3.3V Prec Micropwr LDO Low VRef

Precision Micropower,  Low Dropout Voltage References

GENERAL DESCRIPTION REF196GSZ

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 micropower, 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 μA 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 μA.
