This • Ultralow Dropout Voltage: 30 mV Typical (150-mA topology is stable using output capacitors with low Load) equivalent series resistance (ESR), and even allows operation without a capacitor. The device also • Excellent Load Transient Response—With or provides high reverse blockage (low reverse current) Without Optional Output Capacitor and ground pin current that is nearly constant over all • New NMOS Topology Provides Low Reverse values of output current. Leakage Current The TPS731xx uses an advanced BiCMOS process • Low Noise: 30 μVRMS Typical (10 kHz to 100 kHz) to yield high precision while delivering very low • 0.5% Initial Accuracy dropout voltages and low ground pin current. Current consumption, when not enabled, is less than 1 μA • 1% Overall Accuracy Over Line, Load, and and ideal for portable applications. The extremely low Temperature output noise (30 μVRMS with 0.1-μF CNR) is ideal for • Less Than 1- μA Maximum IQ in Shutdown Mode powering VCOs. These devices are protected by • Thermal Shutdown and Specified Minimum and thermal shutdown and foldback current limit. Maximum Current Limit Protection Device Information(1) • Available in Multiple Output Voltage Versions PART NUMBER PACKAGE BODY SIZE (NOM) – Fixed Outputs of 1.20 V to 5 V TPS731xx SOT-23 (5) 2.90 mm × 1.60 mm – Adjustable Outputs from 1.2 V to 5.5 V (1) For all available packages, see the orderable addendum at – Custom Outputs Available the end of the data sheet. 2 Applications • Smart Grid and Energy • Building Automation • Set-Top Boxes • Medical Equipment • Test and Measurement • Point-of-Sale Terminals • Wireless Infrastructure 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.
