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.
