GENERAL DESCRIPTION
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.
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 an 8-lead SOIC package; the
PDIP and TSSOP packages are available only in the lowest
electrical grade.

Low Dropout Voltage References
REF19x Series
TEST PINS
Test Pin 1 and Test 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. Because
each unit may require a different amount of adjustment, the
resistance value at the test pins varies widely from pin to pin
and from part to part. The user should leave Pin 1 and Pin 5
unconnected.
