LDO (Low Dropout) Linear Voltage Regulators, 1A, LM29xx/LM39xx/LMS81xx Series, Texas Instruments
LDO (Low Dropout) Linear Voltage Regulators, Texas Instruments
A range of Texas Instruments Low Dropout (LDO) Linear Voltage regulators. LDO voltage regulators are able to operate with a small input-output differential making them suitable for a variety of applications where conventional regulators would be unsatisfactory. The latest generation of LDO regulators offers low quiescent current levels and reduced output noise together with excellent line voltage regulation and high PSRR.
