Sipex Corp. has announced that the SPX3819, a Low Dropout (LDO) linear regulator, is now available in 1.8V, 3V, and 3.1V fixed output voltages. The LDO can deliver up to 500mA of continuous output current with 340mV of dropout and low noise output of 40?VRMS.

Suitable for use in portable applications such as cellphones and PDAs, the linear regulator operates from 2.5V to 16V with a supply current of 90?A that drops to nearly zero in shutdown.

The SPX3819 also reduces board space by providing fixed output voltages which eliminate the need for external voltage setting resistors. Other key features include reverse battery protection, foldback current limit, and load dump protection.

Offered in SOT-23 package, the product is priced at 75 cents in 1,000-unit quantities.
