1A 16V high-PSRR linear voltage regulator

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 18V

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.
