Description

The SPX385N-1.2 is a positive voltage regulator designed to provide a low dropout voltage and low noise output. It has a very low ground current of 800µA at 100mA output. The device has an initial tolerance of less than 1% and features a logic compatible ON/OFF switched input. When disabled, power consumption is nearly zero. Other important features include reverse battery protection, current limit, and thermal shutdown. The SPX385N-1.2 also includes a reference bypass pin for optimal low noise output performance and has a very low output temperature coefficient, making it an excellent choice for low power voltage reference applications.
