This topology is stable using • Input Voltage Range: 1.7 V to 5.5 V output capacitors with low equivalent series • Ultralow Dropout Voltage: 40 mV Typical at resistance (ESR), and even allows operation without a capacitor. The device also provides high reverse 250 mA blockage (low reverse current) and ground pin current • Excellent Load Transient Response—With or that is nearly constant over all values of output Without Optional Output Capacitor current. • NMOS Topology Provides Low Reverse Leakage The TPS732 uses an advanced BiCMOS process to Current yield high precision while delivering very low dropout • Low Noise: 30 μVRMS Typical (10 kHz to 100 kHz) voltages and low ground pin current. Current • 0.5% Initial Accuracy consumption, when not enabled, is less than 1 μA and ideal for portable applications. The extremely low • 1% Overall Accuracy (Line, Load, and output noise (30 μVRMS with 0.1-μF CNR) is ideal for Temperature) powering VCOs. These devices are protected by • Less Than 1- μA Maximum IQ in Shutdown Mode thermal shutdown and foldback current limit. • Thermal Shutdown and Specified Min and Max Current Limit Protection Device Information(1) • Available in Multiple Output Voltage Versions PART NUMBER PACKAGE BODY SIZE (NOM) SOT-23 (5) 2.90 mm × 1.60 mm – Fixed Outputs of 1.2 V to 5 V TPS732xx SOT-223 (6) 6.50 mm × 3.50 mm – Adjustable Outputs from 1.2 V to 5.5 V SON (8) 3.00 mm × 3.00 mm – Custom Outputs Available (1) For all available packages, see the orderable addendum at the end of the data sheet. 2 Applications • Portable and Battery-Powered Equipment • Post-Regulation for Switching Supplies • Noise-Sensitive Circuitry such as VCOs • Point-of-Load Regulation for DSPs, FPGAs, ASICs, and Microprocessors Typical Application Circuit for Fixed-Voltage Versions 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.
