This topology is • Input Voltage Range: 2.2V to 5.5V relatively insensitive to output capacitor value and • Ultra-Low Dropout Voltage: 130mV typ at 1A ESR, allowing a wide variety of load configurations. Load transient response is excellent, even with a • Excellent Load Transient Response—Even small 1.0 μF ceramic output capacitor. The NMOS With Only 1.0 μF Output Capacitor topology also allows very low dropout. • NMOS Topology Delivers Low Reverse The TPS737xx family uses an advanced BiCMOS Leakage Current process to yield high precision while delivering very • 1.0% Initial Accuracy low dropout voltages and low ground pin current. • 3% Overall Accuracy Over Line, Load, and Current consumption, when not enabled, is under Temperature 20nA and ideal for portable applications. These devices are protected by thermal shutdown and • Less Than 20nA typical IQ in Shutdown Mode foldback current limit. • Thermal Shutdown and Current Limit for Fault Protection • Available in Multiple Output Voltage Versions – Adjustable Output: 1.20V to 5.5V – Custom Outputs Available Using Factory Package-Level Programming APPLICATIONS • Point of Load Regulation for DSPs, FPGAs, ASICs, and Microprocessors • Post-Regulation for Switching Supplies • Portable/Battery-Powered Equipment (1) Power dissipation may limit operating range.
