This top- • Input Voltage Range: 1.7V to 5.5V ology is stable using output capacitors with low ESR, • Ultralow Dropout Voltage: 40mV Typ at 250mA and even allows operation without a capacitor. It also • Excellent Load Transient Response—with or provides high reverse blockage (low reverse current) without Optional Output Capacitor 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: 30µVRMS Typ (10kHz to 100kHz) dropout voltages and low ground pin current. Current • 0.5% Initial Accuracy consumption, when not enabled, is under 1µA and • 1% Overall Accuracy (Line, Load, and ideal for portable applications. The extremely low Temperature) output noise (30µVRMS with 0.1µF CNR) is ideal for powering VCOs. These devices are protected by • Less Than 1µA Max IQ 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 1.2V, 1.5V, 1.6V, 1.8V, 2.5V, 3.0V, 3.3V, and 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.
