GENERAL DESCRIPTION
REF19x series precision band gap 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 is made up of micropower, Low Dropout
Voltage (LDV) devices providing a stable output voltage from
supplies as low as 100 mV above the output voltage and consum-
ing 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.
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 applications
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.
Test Pins (TP)
The test pins, Pin 1 and Pin 5, are reserved for in-package
Zener-zap. To achieve the highest level of accuracy at the output,
the Zener-zapping technique is used to trim the output voltage.
Since each unit may require a different amount of adjustment, the
resistance value at the test pins will vary widely from pin to pin as
well as from part to part. The user should not make any physical
nor electrical connections to Pin 1 and Pin 5.
