3 Description
The TLV755P is an ultra-small, low quiescent current,
low-dropout regulator (LDO) that sources 500mA
with good line and load transient performance.
The TLV755P is optimized for a wide variety of
applications by supporting an input voltage range
from 1.45V to 5.5V. To minimize cost and solution
size, the device is offered in fixed output voltages
ranging from 0.6V to 5V to support the lower
core voltages of modern microcontrollers (MCUs).
Additionally, the TLV755P has a low IQ with enable
functionality to minimize standby power. This device
features an internal soft-start to lower inrush current,
thus providing a controlled voltage to the load and
minimizing the input voltage drop during start up.
When shutdown, the device actively pulls down the
output to quickly discharge the outputs and provide a
known start-up state.
The TLV755P is stable with small ceramic output
capacitors allowing for a small overall solution size.
A precision band-gap and error amplifier provides
a typical accuracy of 1%. All device versions
have integrated thermal shutdown, current limit, and
undervoltage lockout (UVLO). The TLV755P has an
internal foldback current limit that helps reduce the
thermal dissipation during short-circuit events.
The TLV755 is available in the popular WSON,
X2SON, and SOT23-5 (DRV, DQN, and DBV)
packages. This device is also available in a
thermally enhanced SOT23-5 (DYD) package with
a thermal pad that provides significantly reduced
thermal resistance compared to a standard SOT23-5
package.
