MaxLinear SPX2945
The SPX2945 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 SPX2945 features very low quiescent current (100 A Typ) and very low dropout voltage.GENERAL DESCRIPTION
The SPX2945 is a low power voltage regulator. The SPX2945 features very low quiescent current (100A Typ) and very low dropout voltage. This includes a tight initial tolerance of 1% max and very low output temperature coefficient, making the SPX2945 useful as a low power voltage reference. The SPX2945 is offered in a surface mount 3-pin SOT-223 package. Look for SPX2951 for 150mA and SPX2954 for 250mAapplications. SOT-223 version available. TO-220, TO-263, TO-252, NSOIC versions obsolete For more details about the ordering information, see “Ordering Information” on page 13FEATURES
