3 Description
The TLV759P is an adjustable 1-A low-dropout (LDO)
regulator. This device is available in a small, 6-pin,
2-mm × 2-mm WSON package and consumes very
low quiescent current and provides fast line and load
transient performance. The TLV759P features an
ultra-low dropout of 225 mV at 1 A that can help
improve the power efficiency of the system.
The TLV759P is optimized for a wide variety of
applications by supporting an input voltage range
from 1.5 V to 6.0 V and an externally adjustable
output range of 0.55 V to 5.5 V. The low output
voltage enables this LDO to power the modern
microcontrollers with lower core voltages.
Additionally, the TLV759P has a low IQ with enable
functionality to minimize standby power. This device
features an internal soft-start to lower the inrush
current, which provides a controlled voltage to the
load and minimizes the input voltage drop during start
up.
The TLV759P is stable with small ceramic output
capacitors, allowing for a small overall solution size.
A precision band-gap and error amplifier provides a
high accuracy of 0.7% max at 25ºC and 1% max over
temperature (85ºC). This device includes integrated
thermal shutdown, current limit, and undervoltage
lockout (UVLO) features. The TLV759P has an
internal foldback current limit that helps reduce the
thermal dissipation during short-circuit events.
