DESCRIPTION
The TLV710 and TLV711 series of dual, low-dropout
(LDO) linear regulators are low quiescent current
devices with excellent line and load transient
performance. These LDOs are designed for
power-sensitive applications. These devices provide
a typical accuracy of 2% over temperature.
The TLV711 series provides an active pulldown
circuit to quickly discharge the outputs.
In addition, the TLV711-D series of devices have
pull-down resistors at the EN pins. This design helps
in disabling the device when the signal-driving EN
pins are in a weak, indeterminate state (for example,
the GPIO of a processor that might be three-stated
during startup). The pull-down resistor pulls the
voltage to the EN pins down to 0V, thus disabling the
device.
The TLV710 and TLV711 series are available in a
1.5mm x 1.5mm SON-6 package, and are ideal for
handheld applications.
