3 Description
The TLV733P-Q1 family of low dropout (LDO) linear
regulators 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 TLV733P-Q1 family 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.
Furthermore, the TLV733P-Q1 family is also stable
with ceramic output capacitors if an output capacitor
is necessary. The TLV733P-Q1 family 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 TLV733P-Q1 family provides an active pulldown
circuit to quickly discharge output loads when
disabled.
The TLV733P-Q1 family is available in the 6-pin DRV
(WSON) package.
