Technical Attributes

DESCRIPTIONThe 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 800µA 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.FEATURES■ Low Noise: 40µV Possible■ High Accuracy: 1%■ Reverse Battery Protection■ Low Dropout: 340mV at Full Load■ Low Quiescent Current: 90µA■ Zero Off-Mode Current■ Fixed Output: 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.1V, 3.3V, 5.0V.
