PRODUCT DESCRIPTION
The SPX3819 is a low powered positive voltage regulator with ultra low noise output and very low voltage dropout. In addition, this
device offers very low quiescent current of approximately 800uA at 100mA output. The SPX3819 initial tolerance is less than 1%
max with logic compatible ON/OFF switching input. The unique feature of SPX3819 includes a reference bypass pin for the best
results of low noise.
This device is an excellent choice for the use in battery-powered applications such as cordless telephones, radio control systems, and
portable computers. When disable power consumption drop to nearly zero. This device has a very low output temperature coefficient,
making it a low power voltage reference. The key features include protection against reversed battery, fold-back current limiting, and
automotive load dump protection.
The SPX3819 is available in several fixed voltages 2.5V, 3.3V, 5.0V or adjustable output. This device is offered in SO-8, 3 and 5 pin
TO-263, SOT-223, 5-pin SOT-23 & 3-pin TO-220. These packages offer all the features and adjustable output.
