TD5830  _{3A Low Dropout Regulator with Enable}

(DATASHEET)

The TD5830 is a high performance positive voltage regulator designed for use in applications requiring very low Input voltage and very low dropout voltage at up to 3 amps. It operates with a VIN as low as 1.6V and VPP voltage 5V with output voltage programmable as low as 0.8V. The TD5830 features ultra low dropout, ideal for applications where VOUT  is very close to VIN. Additionally, the TD5830 has an enable pin to further reduce power dissipation while shutdown. The TD5830 provides excellent regulation over variations in line, load and temperature. The TD5830 provides a power OK signal to indicate if the voltage level of VO reaches 92% of its rating value.The TD5830 is available in the power SOP-8PP pack- age. It is available with 1.2V, 1.5V, 1.8V and 2.5V in- ternally preset outputs that are also adjustable using external resistors
