3 Description

The TLV704 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.

Thus, the TLV704 is designed for battery-powered

applications and as a power-management attachment

to low-power microcontrollers.

The TLV704 LDO supports a low dropout of typically

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

current (3.4 μA typically) is stable over the entire

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

TLV704 also features an internal soft-start to lower the

inrush current. The built-in overcurrent limit protection

helps protect the regulator in the event of a load short

or fault.

The TLV704 is available in a 2.90-mm × 1.60-mm

SOT23-5 package, which is useful for cost-effective

board manufacturing.
