These LDOs are designed for – 40mV at IOUT = 50mA and VOUT = 2.8V power-sensitive applications. These devices provide • 2% Accuracy Over Temperature a typical accuracy of 2% over temperature. • Low IQ of 35mA per Regulator The TLV711 series provides an active pulldown • Multiple Fixed Output Voltage Combinations circuit to quickly discharge the outputs. Possible from 1.2V to 4.8V In addition, the TLV711-D series of devices have • High PSRR: 70dB at 1kHz pull-down resistors at the EN pins. This design helps • Stable with Effective Capacitance of 0.1mF(1) in disabling the device when the signal-driving EN pins are in a weak, indeterminate state (for example, • Over-Current and Thermal Protection the GPIO of a processor that might be three-stated • Dedicated VREF for Each Output Minimizes during startup). The pull-down resistor pulls the Crosstalk voltage to the EN pins down to 0V, thus disabling the • Available in 1.5mm × 1.5mm SON-6 Package device. (1) See the Input and Output Capacitor Requirements in the The TLV710 and TLV711 series are available in a Application Information section 1.5mm x 1.5mm SON-6 package, and are ideal for handheld applications. APPLICATIONS • Wireless Handsets, Smart Phones, PDAs • MP3 Players and Other Handheld Products Typical Application Circuit 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. 2All trademarks are the property of their respective owners.
