Product Summary
The TPS79401DGNT is a low-dropout (LDO) low-power linear voltage regulator features high power-supply rejection ratio (PSRR), ultralow-noise, fast start-up, and excellent line and load transient responses in NanoStar wafer chip scale and SOT23 packages. NanoStar packaging gives an ultrasmall footprint as well as an ultralow profile and package weight, making it ideal for portable applications such as handsets and PDAs. The applications of the TPS79401DGNT include RF: VCOs, Receivers, ADCs, Audio, Cellular and Cordless Telephones, Bluetooth, Wireless LAN, Handheld Organizers, PDAs.
