SPX2945

SPX2945 Data Sheet 400mA Low Dropout Voltage Regulator General Description 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. 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 13 Features ■ Output 3.3V at 400mA output ■ Very low quiescent current, 100μA ■ Low dropout voltage, 420mV at 400mA ■ Extremely tight load and line regulation ■ Very low temperature coefficient ■ Current and thermal limiting Applications ■ Networking ■ Telecommunications ■ Industrial systems ■ FPGA and uC’s based systems ■ Remote controlled vehicles P P www.maxlinear.com 243DSR00 Figure 1: SPX2945 Typical Application SPX2945 Data Sheet Revision History Document No. 243DSR00 Release Date May 17, 2023 - 3/14/06 Revision History Change Description Updated: ■ New template applied, contents rewriting, and obsolete packages highlighted. ■ Subtitle updated from "400mA Low Dropout...
