DESCRIPTION
TheSP6200andSP6201areCMOSLowDropout(LDO)regulatorsdesignedtomeetabroadrangeofapplicationsthat
require accuracy, speed and ease of use. These LDOs offer extremely low quiescent current which only increases
slightly under load, thus providing advantages in ground current performance over bipolar LDOs. The LDOs handle an
extremely wide load range and guarantee stability with a 1µF ceramic output capacitor. They have excellent low
frequency Power Supply Rejection Ratio (PSRR), not found in other 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.
The SP6200/6201 is available in fixed and adjustable output voltage versions in tiny DFN and small SOT-23-5
packages. A VOUT good indicator is provided on all fixed output versions.
