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.
