3 Description

The TLV761 is a linear voltage regulator that

improves on the functionality of a traditional x1117

regulator (TLV1117 or LM1117) by reducing ground

current to reduce the standby power while improving

inrush performance. The TLV761 is pin-to-pin

compatible with a fixed SOT-223 regulator.

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

and provides an output voltage range from 1.2 V to

13 V to support a wide variety of applications.

Additionally, the TLV761 has an internal soft start to

reduce the inrush current during startup, 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.

The TLV761 is available in a SOT-223 package.
