Description

The TPS73130DBVR family of low-dropout (LDO) linear voltage regulators uses a new topology: an NMOS pass element in a voltage-follower configuration. This topology is stable using output capacitors with low ESR, and even allows operation without a capacitor. It also provides high reverse blockage (low reverse current) and ground pin current that is nearly constant over all values of output current. The TPS731xx 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 1 μA and ideal for portable applications. The extremely low output noise (30μVRMS with 0.1μF CNR) is ideal for powering VCOs. These devices are protected by thermal shutdown and foldback current limit. TPS73130DBVR Features• Stable with No Output Capacitor or Any Value or Type of Capacitor• Input Voltage Range of 1.7V to 5.5V• Ultralow Dropout Voltage: 30mV Typ• Excellent Load Transient Response—with or without Optional Output Capacitor• New NMOS Topology Provides Low Reverse Leakage Current• Low Noise: 30μVRMS Typ (10kHz to 100kHz)• 0.5% Initial Accuracy• 1% Overall Accuracy over Line, Load, and Temperature• Less Than 1μA Max IQ in Shutdown Mode• Thermal Shutdown and Specified Min/Max Current Limit Protection• Available in Multiple Output Voltage Versions– Fixed Outputs of 1.20V to 5.0V– Adjustable Outputs from 1.20V to 5.5V– Custom Outputs Available TPS73130DBVR Applications• Portable/Battery-Powered Equipment• Post-Regulation for Switching Supplies• Noise-Sensitive Circuitry such as VCOs• Point of Load Regulation for DSPs, FPGAs, ASICs, and Microprocessors
