3 Description
The TLV755P is an ultra-small, low quiescent current,
low-dropout regulator (LDO) that sources 500 mA
with good line and load transient performance. The
TLV755P is optimized for a wide variety of
applications by supporting an input voltage range
from 1.45 V to 5.5 V. To minimize cost and solution
size, the device is offered in fixed output voltages
ranging from 0.6 V to 5 V 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 ensure 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.
