This • Input Voltage Range: 1.7V to 5.5V topology is stable using output capacitors with low • Ultralow Dropout Voltage: 40mV Typ at ESR, and even allows operation without a capacitor. 250mA It also provides high reverse blockage (low reverse • Excellent Load Transient Response—with or current) and ground pin current that is nearly without Optional Output Capacitor constant over all values of output current. • New NMOS Topology Provides Low Reverse The TPS732xx uses an advanced BiCMOS process Leakage Current to yield high precision while delivering very low dropout voltages and low ground pin current. Current • Low Noise: 30 µV RMS Typ (10kHz to 100kHz) consumption, when not enabled, is under 1 µA and • 0.5% Initial Accuracy ideal for portable applications. The extremely low • 1% Overall Accuracy (Line, Load, and output noise (30 µV RMS with 0.1µF CNR) is ideal for Temperature) powering VCOs. These devices are protected by thermal shutdown and foldback current limit. • Less Than 1 µA Max I Q in Shutdown Mode • Thermal Shutdown and Specified Min/Max Current Limit Protection • Available in Multiple Output Voltage Versions – Fixed Outputs of 1.20V to 5.0V – Adjustable Outputs from 1.20V to 5.5V – Custom Outputs Available • Portable/Battery-Powered Equipment • Post-Regulation for Switching Supplies • Noise-Sensitive Circuitry such as VCOs • Point of Load Regulation for DSPs, FPGAs, ASICs, and Microprocessors 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.
