PRODUCT DESCRIPTION

The SPX1129 is a low power voltage regulator. This device is an excellent choice for use in battery-powered applications such as cordless telephones, radio control systems, and portable computers. The SPX1129 features very low quiescent current and very low dropout voltage of 0.4 volts. This includes a tight initial tolerance of ± 1 max, and very low output temperature coefficient, making the SPX1129 useful as a low-power voltage reference.
