3 Description

The TLV733 series of low-dropout linear regulators

(LDOs) are ultra-small, low quiescent current LDOs

that can source 300 mA with good line and load

transient performance. These devices provide a

typical accuracy of 1%.

The TLV733 series is designed with a modern

capacitor-free architecture to ensure stability without

an input or output capacitor. The removal of the

output capacitor allows for a very small solution size,

and can eliminate inrush current at startup. However,

the TLV733 series is also stable with ceramic output

capacitors if an output capacitor is necessary. The

TLV733 also provides foldback current control during

device power-up and enabling if an output capacitor

is used. This functionality is especially important in

battery-operated devices.

The TLV733 provides an active pull-down circuit to

quickly discharge output loads when disabled.

The TLV733 series is available in standard DBV

(SOT-23) and DQN (X2SON) packages.
