Product Summary

The TPS79633DCQR is a low-dropout (LDO) low-power linear voltage regulator features high power supply rejection ratio (PSRR), ultra low-noise, fast start-up, and excellent line and load transient responses in small outline, 3 x 3 SON, SOT223-6, and 5-pin DDPAK packages. Each device in the family is stable with a small 1-μF ceramic capacitor on the output. The applications of the TPS79633DCQR include RF: VCOs, Receivers, ADCs, Audio, Bluetooth, Wireless LAN, Cellular and Cordless Telephones, Handheld Organizers, PDAs.
