This topology is • Input Voltage Range: 2.2 V to 5.5 V relatively insensitive to output capacitor value and • Ultralow Dropout Voltage: ESR, allowing a wide variety of load configurations. Load transient response is excellent, even with a – 200-mV Maximum at 1 A small 1- μF ceramic output capacitor. The NMOS • Excellent Load Transient Response—Even With topology also allows very low dropout. Only 1- μF Output Capacitor The TPS7A37 family uses an advanced BiCMOS • NMOS Topology Delivers Low Reverse Leakage process to yield high precision while delivering very Current low dropout voltages and low ground pin current. • Excellent Accuracy: Current consumption, when not enabled, is under 20 nA and ideal for portable applications. These devices – 0.23% Nominal Accuracy are protected by thermal shutdown and foldback – 1% Overall Accuracy Over Line, Over Load, current limit. and Over Temperature • Less Than 20-nA typical IQ in Shutdown Mode Device Information(1) • Thermal Shutdown and Current Limit for Fault PART NUMBER PACKAGE BODY SIZE (NOM) Protection TPS7A37 WSON (6) 2.00 mm × 2.00 mm (1) For all available packages, see the orderable addendum at 2 Applications the end of the data sheet. • Point of Load Regulation for DSPs, FPGAs, ASICs, and Microprocessors • Post-Regulation for Switching Supplies • Portable and Battery-Powered Equipment SPACE Typical Application Circuit (Adjustable Version) Typical Application Circuit (Fixed Version) 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
