SBVS068G–FEBRUARY 2006–REVISED APRIL 2009 LowNoise,High-BandwidthPSRR Low-Dropout150mALinearRegulator 23 • 150mA Low-Dropout Regulator with Enable The TPS717xx family of low-dropout (LDO), low-power linear regulators offers very high power • Low I Q : 45 μ A (typical) supply rejection (PSRR) while maintaining very low • Available in Multiple Output Versions: 45 μ A ground current in an ultra-small, five-pin SC70 – Fixed Output with Voltages from 0.9V to package. The family uses an advanced BiCMOS 5.0V Using Innovative Factory EEPROM process and a PMOSFET pass device to achieve fast Programming start-up, very low noise, excellent transient response, and excellent PSRR performance. The TPS717xx is – Adjustable Output Voltage from 0.9V to stable with a 1.0 μ F ceramic output capacitor, and 6.2V uses a precision voltage reference and feedback loop • Ultra-High PSRR: to achieve a worst-case accuracy of 3% over all load, – 70dB at 1kHz, 67dB at 100kHz and 45dB at line, process, and temperature variations. It is fully 1MHz specified from T J = –40°C to +125°C and is offered in a small SC70-5 package, a 2mm × 2mm SON-6 • Low Noise: 30 μ V typical (100Hz to 100kHz) package with a thermal pad, and a 1.5mm × 1.5mm • Stable with a 1.0 μ F Ceramic Capacitor SON package, which are ideal for small form factor • Excellent Load/Line Transient Response portable equipment such as wireless handsets and PDAs. • 3% Overall Accuracy (over Load/Line/Temp) • Over-Current and Over-Temperature Protection • Very Low Dropout: 170mV Typical at 150mA • Small SC70-5, 2mm x 2mm SON-6, and 1.5mm × 1.5mm SON-6 Packages • Mobile Phone Handsets • Wireless LAN, Bluetooth ® • PDAs and Smartphones 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 Bluetooth is a registered trademark of Bluetooth SIG, Inc....
