The LM1117-Q1 is a AEC-Q100 qualified linear voltage regulator for automotive applications that provides improved performance compared to traditional x1117 regulators with tighter output accuracy and low quiescent current (IQ) to lower the standby power consumption.

The LM1117-Q1 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 LM1117-Q1 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 LM1117-Q1 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 LM1117-Q1 features a foldback current limit that limits the power dissipation of the device during high-load current faults or shorting events.
