Product Summary

The TPS79901DDCR is a low-dropout (LDO) low-power linear regulator offers excellent AC performance with very low ground current. High power-supply rejection ratio (PSRR), low noise, fast start-up, and excellent line and load transient response are provided while consuming a very low 40μA (typical) ground current. The applications of the TPS79901DDCR include Cellular Phones, Wireless LAN, Bluetooth, VCOs, RF, Handheld Organizers, PDAs.
