We offer a broad line of high performance low dropout (LDO) linear regulators with fasttransient response, excellent line and load regulation, and very wide input voltage rangefrom 0.9V to 100V. Output currents range from 20mA to 10A, with positive, negative andmultiple output versions available. Many devices offer output voltage operation <0.8V andsome feature operation as low as 0V, even with a single supply. Most are stable with ceramicoutput capacitors. LDO regulators can be applied in virtually any application.

Abstract: This application note helps system designers choose the correct external components for use with the MAX16948 dualremote antenna LDO/switch, thus ensuring that automobile-regulated phantom antenna supply and output-current-monitoring circuitrymeet performance objectives. An electronic calculator is provided that helps specify the critical external components for theMAX16948, thus reducing design time. The calculator also determines the device's analog output voltage, output current-limitthreshold, and output current-sensing accuracies. The calculator includes new automatic Step By Step feature that assists designerswith component choice. To use the new automatic feature, click on the Step By Step button relative to the desired section.
