DESCRIPTION  
The SPX3819 is a positive voltage regulator with a low dropout voltage and low noise output. In addition,  
thisdeviceoffersaverylowgroundcurrentof800µAat100mAoutput.TheSPX3819hasaninitialtolerance  
of less than 1% max and a logic compatible ON/OFF switched input. When disabled power consumption  
drop to nearly zero. Other key features include reverse battery protection, current limit, and thermal  
shutdown. The SPX3819 includes a reference bypass pin for optimal low noise output performance. With  
its very low output temperature coefficient, this device also makes a superior low power voltage reference.  
The SPX3819 is an excellent choice for use in battery-powered applications such as cordless telephones,  
radio control systems, and portable computers. It is available in several fixed voltages 1.2V, 1.5V, 1.8V,  
2.5V, 3.0V, 3.1V, 3.3V, 5.0V or with an adjustable output. This device is offered in 8 pin nSOIC, 8 pin DFN  
and 5-pin SOT-23 packages.
