TLV76150DCYR

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 (I_Q) to lower the standby power consumption. The TLV761 is pin-to-pin compatible with other fixed SOT-223 regulators. The TLV761 input voltage range is from 2.5 V to 16 V and provides an output voltage range from 0.8 V to 13 V to support a wide variety of applications. The wide bandwidth PSRR performance of the TLV761 is typically greater than 60 dB at 1 kHz and 40 dB at 1 MHz, 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.
