150mA, High PSRR, Low Quiescent Current, Low Noise LDO - TPS717
 

Description

The TPS717xx family of low-dropout (LDO), low-power linear regulators offers very high power-supply rejection (PSRR) while maintaining very low 45-µA ground current in an ultra-small, five-pin SOT package. The family uses an advanced BiCMOS process and a PMOS pass device to achieve fast start-up, very low noise, excellent transient response, and excellent PSRR performance. The TPS717xx is stable with a 1-µF ceramic output capacitor and uses a precision voltage reference and feedback loop to achieve a worst-case accuracy of 3% over all load, line, process, and temperature variations. The device family is fully specified from TJ = –40°C to 125°C and is offered in a small SOT (SC70-5) package, a 2-mm × 2-mm WSON-6 package with a thermal pad, and a 1.5-mm × 1.5-mm WSON-6 package, which are ideal for small form factor portable equipment (such as wireless handsets and PDAs).

Features

  • Input Voltage: +2.5 V to +6.5 V
  • Available in Multiple Output Versions:
    • Fixed Output with Voltages from 0.9 V to 5 V
    • Adjustable Output Voltage from 0.9 V to 6.2 V
  • Ultra-High PSRR:
    • 70 dB at 1 kHz, 67 dB at 100 kHz, and 45 dB at 1 MHz
  • Excellent Load and Line Transient Response
  • Very Low Dropout: 170 mV typical at 150 mA
  • Low Noise: 30 µVRMS typical (100 Hz to 100 kHz)
  • Small 5-pin SC-70, 2-mm × 2-mm WSON-6, and
    1.5-mm × 1.5-mm WSON-6 Packages
