The SPX3819 is a positive voltage regulator with a low dropout voltage and low noise output. In
addition, this device offers a very low ground current of 800
μ
A at 100mA output. The SPX3819 has
an initial tolerance of less than 1% max and a logic compatible ON/OFF switched input. When
disabled, power consumption drops 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.
