Dual, 200mA, Low-IQ
Low-Dropout Regulator for Portable Devices
1FEATURES DESCRIPTION
2• Very Low Dropout: The TLV710 and TLV711 series of dual, low-dropout
– 150mV at IOUT = 200mA and VOUT = 2.8V (LDO) linear regulators are low quiescent current
– 75mV at I devices with excellent line and load transient OUT = 100mA and VOUT = 2.8V
performance. 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
