This • Input Voltage Range: 1.7V to 5.5V topology is stable using output capacitors with low • Ultralow Dropout Voltage: 40mV Typ at 250mA ESR, and even allows operation without a capacitor. • Excellent Load Transient Response—with or It also provides high reverse blockage (low reverse without Optional Output Capacitor current) and ground pin current that is nearly constant over all values of output current. • New NMOS Topology Provides Low Reverse Leakage Current The TPS732xx uses an advanced BiCMOS process to yield high precision while delivering very low • Low Noise: 30µV RMS Typ (10kHz to 100kHz) dropout voltages and low ground pin current. Current • 0.5% Initial Accuracy consumption, when not enabled, is under 1 µA and • 1% Overall Accuracy (Line, Load, and ideal for portable applications. The extremely low Temperature) output noise (30 µV RMS with 0.1µF CNR) is ideal for powering VCOs. These devices are protected by • Less Than 1µA Max I Q in Shutdown Mode thermal shutdown and foldback current limit. • 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 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 All trademarks are the property of their respective owners.
