3 Description

The TLV709 low-dropout (LDO) linear voltage

regulator is a low quiescent current device. This

device offers the benefits of a wide input voltage

range and low-power operation in miniaturized

packaging. The TLV709 is optimized to power

microcontrollers and other low power loads for

battery-powered applications.

The TLV709 LDO supports a low dropout of typically

600mV at 100mA of load current. The low quiescent

current (3.2μA typically) does not vary across the

entire range of output load current (0mA to 150mA).

The TLV709 also features an internal soft-start to

lower inrush current during start-up. The built-in

overcurrent limit protection helps protect the regulator

in the event of a load short or fault condition.

The TLV709 is available in 2.9mm × 2.8mm, 5-pin

SOT-23 (DBV), 2.92mm × 2.37mm, 3-pin SOT-23

(DBZ), and 4.5mm × 2.5mm, 3-pin SOT-89 (PK)

packages, The DBV package is for fixed and

adjustable outputs and the DBZ package is only for

fixed outputs.
