LM117: rad-hard LDO with an Enable pin

Part Number: LM117

Hi,

Does TI have a rad-hard LDO with an Enable pin?

I need three different voltages and of course could use three of the same part number adjustable LDO's.

1.  Input voltage  5V, output voltage 3.3 volts, max output current 100 mA.

2.  Input voltage 5V, output voltage 1.8 volts, max output current 100 mA.

3.  Input voltage 5V, output voltage 1.25 volts, max output current 100 mA.

    Hi Kenneth,

    We have a couple of options, but TPS7H1101A-SP may be the best fit given your described needs. 

    For a more comprehensive list you can look use our product search and filter by Device Grade and selecting Space grade products. Here is a quick search I did adding filters for parts with at least a 5V max Vin, be able to supply at least 100mA and has the Enable feature; this results in 5 possible family of parts that might work for you.
