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.  
NC = NO CONNECT  
TP PINS ARE FACTORY TEST POINTS  
NO USER CONNECTION  
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 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 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.
