TPS73433-Q1 Datasheet | Texas Instruments

ATURES - Qualified for Automotive Applications - 250m A Low Dropout Regulator with EN - Low IQ: 44μA - Multiple Output Voltage Versions Available: - Fixed 3.3V Outputs - Adjustable Outputs from 1.25V to 6.2V - High PSRR: 60d B at 1k Hz - Ultra-Low Noise: 28μVRMS - Fast Start-Up Time: 45μs - Stable with a Low-ESR, 2.0μF Typical Output Capacitance - Excellent Load/Line Transient Response - 2% Overall Accuracy (Load/Line/Temp) - Thin SOT-23 Package DESCRIPTION The TPS734xx-Q1 family of low-dropout (LDO), low-power linear regulators offers excellent ac performance with very low ground current. High power-supply rejection ratio (PSRR), low noise, fast start-up, and excellent line and load transient response are provided while consuming a very low 44μA (typical) ground current. The TPS734xx-Q1 is stable with ceramic capacitors and uses an advanced Bi CMOS fabrication process to yield a typical dropout voltage of 125m V at 250m A output. The TPS734xx-Q1 uses a precision voltage reference and feedback loop to achieve overall accuracy of 2% over all load, line, process, and temperature variations. It is fully specified from TA = - 40°C to +105°C and is offered in a low-profile Thin SOT-23 package that are ideal for wireless handsets, printers, and WLAN cards.
