Product Summary

The TPS79633DCQR 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 small outline, 3 × 3 SON, SOT223-6, and DDPAK-5 packages. Each device in the family is stable with a small 1mF ceramic capacitor on the output. The family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (e.g., 250mV at 1A). The applications of the include RF: VCOs, Receivers, ADCs, Audio, Bluetooth, Wireless LAN, Cellular and Cordless Telephones, Handheld Organizers, PDAs.
