SBVS123 – DECEMBER 2008 1-A LOW-DROPOUT REGULATOR WITH REVERSE CURRENT PROTECTION 2 • Qualified for Automotive Applications • Thermal Shutdown and Current Limit for Fault Protection • Stable with 1.0-µF or Larger Ceramic Output Capacitor • Available in Multiple Output Voltage Versions • Input Voltage Range: 2.2 V to 5.5 V – Adjustable Output: 1.20 V to 5.5 V • Ultra-Low Dropout Voltage: 130 mV typ at 1 A – Custom Outputs Available Using Factory Package-Level Programming • Excellent Load Transient Response, Even With Only 1.0- µF Output Capacitor • NMOS Topology Delivers Low Reverse • Point of Load Regulation for DSPs, FPGAs, Leakage Current ASICs, and Microprocessors • 1.0% Initial Accuracy • Post-Regulation for Switching Supplies • 3% Overall Accuracy Over Line, Load, and • Portable/Battery-Powered Equipment Temperature • Less Than 20-nA (Typ) Quiescent Current in Shutdown Mode The TPS737xx family of linear low-dropout (LDO) voltage regulators uses an NMOS pass element in a voltage-follower configuration. This topology is relatively insensitive to output capacitor value and ESR, allowing a wide variety of load configurations. Load transient response is excellent, even with a small 1.0- µF ceramic output capacitor. The NMOS topology also allows very low dropout. The TPS737xx family uses an advanced BiCMOS process to yield high precision while delivering very low dropout voltages and low ground pin current. Current consumption, when not enabled, is under 20 nA and ideal for portable applications. These devices are protected by thermal shutdown and foldback current limit.
