What are the key features of LM117GWRQMLV?
- Wide adjustable output voltage range of 1.2 V to 37 V covers a broad set of analog and mixed-signal supply requirements with a single device
- 40 V maximum input voltage and 500 mA output current support automotive and industrial applications powered from unregulated vehicle battery rails
- 16-pin CSOIC surface-mount package allows easy PCB integration with improved thermal dissipation compared to traditional 3-pin through-hole regulators
What is LM117GWRQMLV used for?
The LM117GWRQMLV is used in automotive ECUs, body-control modules, and industrial instrumentation where a precise adjustable voltage rail from 1.2 V to 37 V is required from a high-voltage input source. Its 500 mA current capability and 40 V input tolerance make it suitable for powering op-amp supplies, reference voltages, and analog sensor rails directly from a 12 V or 24 V battery bus. The device also fits laboratory-grade power supplies and test equipment that demand low-noise linear regulation without a switching converter.

Frequently Asked Questions
What output voltage range can be set on the LM117GWRQMLV, and how is it adjusted?
The LM117GWRQMLV output is adjustable from 1.2 V to 37 V using a standard two-resistor divider network connected to the adjustment pin. The reference voltage between the output and the adjust pin is typically 1.25 V, which sets the minimum output. This approach allows designers to dial in any voltage within the range by choosing appropriate resistor values, making the device highly versatile for multi-rail analog supply designs.
What is the maximum input voltage and output current the LM117GWRQMLV supports?
The device accepts an input voltage up to 40 V and delivers up to 500 mA of continuous output current. The input-to-output voltage differential must remain between 3 V minimum and 40 V maximum for proper regulation, which is important when selecting input capacitors and planning the dropout budget in automotive 12 V or 24 V battery-powered systems.
Is the LM117GWRQMLV suitable for automotive applications, and what is its qualification status?
Yes, the QMLV suffix indicates qualification to MIL or automotive reliability screening, and the part is offered in an automotive-grade surface-mount 16-pin CSOIC package. Its wide input range of 4.2 V to 40 V covers the full cold-crank to load-dump voltage excursions seen on a 12 V vehicle electrical system, making it a robust choice for ECU analog power rails.
How does the 16-pin CSOIC package of the LM117GWRQMLV compare to a standard 3-pin TO-220 LDO for PCB integration?
The 16-pin CSOIC is a surface-mount package with a smaller footprint than a TO-220 through-hole device, enabling reflow-soldering assembly and smaller PCB area. Multiple pins are internally connected in parallel for the input, output, and ground nodes, which reduces package thermal resistance and allows the 500 mA rated current to be delivered with lower junction temperature rise compared to a single-pin approach in a narrow 3-pin package.
