Product Summary
The SPX3819M5-L 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 SPX3819M5-L9 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 SPX3819M5-L includes a reference bypass pin for optimal low noise output performance. The applications of the SPX3819M5-L include Battery Powered Systems, Cordless Phones, Radio Control Systems, Portable/Palm Top/Notebook Computers, Portable Consumer Equipment, Portable Instrumentation, Bar Code Scanners, SMPS Post Regulators.
