This • Ultra-Low Dropout Voltage: 75mV typ topology is stable using output capacitors with low • Excellent Load Transient Response—with or ESR, and even allows operation without a capacitor. without Optional Output Capacitor It also provides high reverse blockage (low reverse current) and ground pin current that is nearly constant • New NMOS Topology Delivers Low Reverse over all values of output current. Leakage Current • Low Noise: 30mVRMS typ (10Hz to 100kHz) The TPS736xx uses an advanced BiCMOS process to yield high precision while delivering very low • 0.5% Initial Accuracy dropout voltages and low ground pin current. Current • 1% Overall Accuracy Over Line, Load, and consumption, when not enabled, is under 1mA and Temperature ideal for portable applications. The extremely low • Less Than 1mA max IQ in Shutdown Mode output noise (30mVRMS with 0.1mF CNR) is ideal for powering VCOs. These devices are protected by • Thermal Shutdown and Specified Min/Max thermal shutdown and foldback current limit. Current Limit Protection space • Available in Multiple Output Voltage Versions – Fixed Outputs of 1.20V to 5.0V – Adjustable Output from 1.20V to 5.5V – Custom Outputs Available 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 space 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
