3 Description

The TLV709 low-dropout (LDO) linear voltage

regulator is a low quiescent current device that

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

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

current (3.2 μA typically) does not vary across the

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

The TLV709 also features an internal soft-start to

lower the 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 a 2.90-mm × 1.60-mm,

5-pin SOT-23 (DBV) package for fixed and adjustable

outputs, and in a 4.50-mm × 2.5-mm, 3-pin SOT-89

(PK) package for fixed outputs.
