SBVS067H – JANUARY 2006 – REVISED MAY 2008 1A Low-Dropout Regulator with Reverse Current Protection 2 • Stable with 1.0µF or Larger Ceramic Output Capacitor The TPS737xx family of linear low-dropout (LDO) voltage regulators uses an NMOS pass element in a • Input Voltage Range: 2.2V to 5.5V voltage-follower configuration. This topology is • Ultra-Low Dropout Voltage: 130mV typ at 1A relatively insensitive to output capacitor value and • Excellent Load Transient Response—Even ESR, allowing a wide variety of load configurations. With Only 1.0µF Output Capacitor Load transient response is excellent, even with a small 1.0µF ceramic output capacitor. The NMOS • NMOS Topology Delivers Low Reverse topology also allows very low dropout. Leakage Current • 1.0% Initial Accuracy The TPS737xx family uses an advanced BiCMOS process to yield high precision while delivering very • 3% Overall Accuracy Over Line, Load, and low dropout voltages and low ground pin current. Temperature Current consumption, when not enabled, is under • Less Than 20nA typical I Q in Shutdown Mode 20nA and ideal for portable applications. These • Thermal Shutdown and Current Limit for Fault devices are protected by thermal shutdown and foldback current limit. Protection • Available in Multiple Output Voltage Versions – Adjustable Output: 1.20V to 5.5V – Custom Outputs Available Using Factory Package-Level Programming • Point of Load Regulation for DSPs, FPGAs, ASICs, and Microprocessors • Post-Regulation for Switching Supplies • Portable/Battery-Powered Equipment 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.
