Texas Instruments TLV705 Low-Noise Low-Dropout Regulators (LDO)

Texas Instruments TLV705 Low-Noise Low-Dropout Regulators (LDO) are low quiescent current devices with excellent line and load transient performance. These devices are designed for power-sensitive applications, with a precision band gap. A built-in error amplifier provides typical accuracy of 0.5%. Low output noise, very high power-supply rejection ratio (PSRR), and low dropout voltage make this series of LDOs ideal for a wide selection of battery-operated hand-held equipment. Each of these devices from Texas Instruments has a thermal shutdown and current limit for safety.
