GENERAL DESCRIPTION
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 less
than 45
μ
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 less
than 15
μ
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 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.
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 out-
put, the zener-zapping technique is used to trim the output
voltage. Since each unit may require a different amount of ad-
justment, 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.
