DESCRIPTION

TheSPX1121isalowpowervoltageregulator. Itisanexcellentchoiceforuseinbattery-powered

applications such as cordless telephones, radio control systems, and portable computers. The

SPX1121 features very low quiescent current and low dropout voltage (typ. 20mV at 100µA and

300mV at 150mA). A tight initial tolerance (1%), extremely good load and line regulation (0.05%

typ.), and very low output temperature coefficient (20 ppm/°C typ.), make the SPX1121 useful

as a low power voltage reference.
