Frequently Asked Questions
What is the maximum input-to-output voltage differential the LM117HVH-QML can sustain, and how does this affect high-voltage supply design?
The LM117HVH-QML is rated for a maximum input-to-output voltage differential of 40 V, with a minimum of 3 V required for regulation. This 40 V headroom allows the regulator to produce a 5 V output directly from a 24 V bus, or a 1.25 V adjustable output from supplies up to 41.25 V, covering a broad range of military and industrial power architectures without an intermediate pre-regulator stage.
How does the LM117HVH-QML's 0.04%/V line regulation specification compare to commercial LDOs for precision reference applications?
At 0.04%/V maximum line regulation, the LM117HVH-QML output shifts by at most 0.4 mV per volt of input change on a 1 V output setting. Commercial-grade LM317 variants typically specify 0.01% to 0.04%/V, but the QML-qualified LM117HVH-QML adds MIL-STD-883 screening to confirm this specification over the full military temperature range, providing assurance that the regulator maintains sub-millivolt accuracy in satellite power conditioning circuits subject to wide input bus swings.
Why is the TO-39 metal-can hermetic package of the LM117HVH-QML required for space and high-reliability applications?
The 3-lead TO-39 (JESD-30 O-MBCY-W3) metal-can package provides hermetic sealing that prevents outgassing and moisture ingress in vacuum or high-humidity environments, meeting MIL-STD-883 package integrity requirements. Plastic packages absorb moisture during storage and can crack during thermal cycling from −55°C to +150°C, whereas the welded metal lid of the TO-39 maintains seal integrity across thousands of thermal cycles in spacecraft or airborne equipment.
How is the output voltage of the LM117HVH-QML programmed, and what resistor values set a 5 V regulated output?
The LM117HVH-QML uses the standard 2-resistor divider between the ADJ pin and output. With a 240 Ω resistor (R1) from output to ADJ, a second resistor R2 from ADJ to ground sets the output to VOUT = 1.25 V × (1 + R2/R1). To obtain 5.0 V, R2 = 720 Ω gives 5.0 V target: 1.25 × (1 + 720/240) = 5.0 V. The minimum 3 V dropout means the input supply must be at least 8 V for stable 5 V regulation.
