3 Description

The TLV740P low-dropout (LDO) linear regulator is a

low quiescent current LDO with excellent line and load

transient performance designed for power-sensitive

applications. This device provides a typical accuracy

of 1%.

The TLV740P also provides inrush current control

during device power up and enabling. The TLV740P

limits the input current to the defined current limit to

avoid large currents from flowing from the input power

source. This functionality is especially important in

battery-operated devices.

The TLV740P is available in standard DQN and DBV

packages. The TLV740P also provides an active

pulldown circuit to quickly discharge output loads.
