3 Description

The TLV761 is a linear voltage regulator that improves

the functionality of a traditional x1117 regulator

(TLV1117 or LM1117) with tighter output accuracy and

low quiescent current (IQ) to lower the standby power

consumption. The TLV761 is pin-to-pin compatible

with other fixed SOT-223, TO-252 regulators.

The TLV761 input voltage range is from 2.5V to 16V

and provides an output voltage range from 0.8V to

13V to support a wide variety of applications.

The wide bandwidth PSRR performance of the

TLV761 is typically greater than 60dB at 1kHz and

40dB at 1MHz, which helps attenuate the switching

frequency of an upstream DC/DC converter and

minimizes post regulator filtering.

Additionally, the TLV761 has an internal soft start

feature to reduce inrush current during start-up,

which can help save space and cost in a design by

minimizing input capacitance. The TLV761 features a

foldback current limit that limits the power dissipation

of the device during high-load current faults or

shorting events.
