URES - 2 250m A Low Dropout Regulator with EN - Low IQ: 44µA - Multiple Output Voltage Versions Available: - Fixed Outputs of 1.0V to 4.3V Using Innovative Factory EEPROM Programming - 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) - Very Low Dropout: 125m V at 250m A - Thin SOT-23, 2mm × 2mm SON-6, and 3mm x 3mm SON-8 Packages DESCRIPTION The TPS734xx 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 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 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 TJ = - 40°C to +125°C and is offered in low-profile Thin SOT-23, 2mm × 2mm SON, and 3mm x 3mm SON packages that are ideal for wireless handsets, printers, and WLAN cards.
