Product Summary

The TPS78618DCQR 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, SOT223-6 and 5-pin DDPAK packages. Each device in the family isstable, with a small 1-μF ceramic capacitor on the output. The applications of the TPS78618DCQR include RF: VCOs, Receivers, ADCs, Audio, Bluetooth, Wireless LAN, Cellular and Cordless Telephones, Handheld Organizers, PDAs.
