SLEEP  
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 a high initial accuracy.

NC = NO CONNECT  
TP PINS ARE FACTORY TEST POINTS,  
NO USER CONNECTION  
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 consuming less than  
45 µA of supply current. In sleep mode, which is enabled by apply-  
ing 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 available only 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  
or electrical connections to Pin 1 and Pin 5.
