LDO Linear Regulator Design Using Universal SOT23 EVM

This user's guide describes techniques for designing low dropout (LDO) voltage linear regulators using TI's SLVP125 evaluation module (EVM) and TPS76933 LDO. LDOs provide ideal power supplies for rapidly transitioning DSP loads such as the Texas Instruments TMS320C54x and similar processors, and fast memory. Low quiescent current and very low dropout voltage compared to standard LDOs makes the TPS76933 particularly suitable in battery applications requiring extended lifetime and low cost. Low noise power supplies, fast transient response, improved efficiency, low component count, and easy design make LDOs popular in solutions where switched converters are too noisy and standard linear regulators are too inefficient.
