DESCRIPTION
TheSP6200andSP6201areCMOSLDOsdesignedtomeetabroadrangeofapplicationsthatrequireaccuracy, speed
and ease of use. These LDOs offer extremely low quiescent current which only increases slightly under load, thus
providingadvantagesingroundcurrentperformanceoverbipolarLDOs.TheLDOshandleanextremelywideloadrange
andguaranteestabilitywitha1µFceramicoutputcapacitor.TheyhaveexcellentlowfrequencyPSRR,notfoundinother
CMOS LDOs and thus offer exceptional Line Regulation. High frequency PSRR is better than 40dB up to 400kHz. Load
Regulation is excellent and temperature stability is comparable to bipolar LDOs. An enable feature is provided on all
versions.

A VOUT good indicator is provided on all fixed output versions.
