The Texas Instruments REG104 is a family of low-noise, low-dropout linear regulators with low ground pin current. Its new DMOS topology provides significant improvement over previous designs, including low dropout voltage (only 230mV typ at full load), and better transient performance. In addition, no output capacitor is required for stability, unlike conventional low dropout regulators that are difficult to compensate and require expensive low ESR capacitors greater than 1μF.

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.
