PRODUCT DESCRIPTION

The SPX2954 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 SPX2954 features very low quiescent current (75μA Typ.) and very low dropout voltage. This includes a tight initial tolerance of ± 0.5 max and ± 1 max., and very low output temperature coefficient, making the SPX2954 useful as a low-power voltage reference. The key SPX2954 features include protection against reversed battery, fold-back current limiting, and automotive load dump protection (60V positive transient).
