TPS78633DCQR Datasheet

LDO Voltage Regulators


The TPS786xx( TPS78633DCQR ) family of low-dropout (LDO) low-power linear voltage regulators 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 DDPAK-5 packages. Each device in the family is stable, with a small 1-mF ceramic capacitor on the output. The family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (for example, 390 mV at 1.5 A). TPS78633DCQR Features • High PSRR (49 dB at 10 kHz)• Ultralow Noise (48 mVRMS, TPS78630)• Fast Start-Up Time (50 ms)• Stable With a 1-mF Ceramic Capacitor• Excellent Load/Line Transient Response• Very Low Dropout Voltage (390 mV at Full Load, TPS78630) TPS78633DCQR Applications • RF: VCOs, Receivers, ADCs• Audio• Bluetooth®, Wireless LAN• Cellular and Cordless Telephones• Handheld Organizers, PDAs
