3 Description
The TLV757P low-dropout regulator (LDO) is an
ultra-small, low quiescent current LDO that sources
1A with good line and load transient performance.
The TLV757P 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. This range supports the lower
core voltages of modern microcontrollers (MCUs).
Additionally, the TLV757P has a low IQ with enable
functionality to minimize standby power. This device
features an internal soft-start to lower the inrush
current. This feature provides a controlled voltage to
the load and minimizes the input voltage drop during
start-up. When shutdown, the device actively pulls
down the output to quickly discharge the outputs and
provides a known start-up state.
The TLV757P 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 TLV757P has
an internal foldback current limit that helps reduce
thermal dissipation during short-circuit events.
The TLV757 is available in the popular SON and
SOT23-5 packages. This device is also available in
a thermally enhanced SOT23-5 package (DYD) with
a thermal pad. This package provides significantly
reduced thermal resistance compared to a standard
SOT23-5 package.
