The SPX1121 is a low power voltage regulator. It is an excellent choice for use in battery-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 100
μ
A 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.
