Long term stability: 0.5% typ.

I'm thinking of using this device as I have 12 volt dc supply to be an input. Will I get 3.3 volts fixed supplying a 2 mA load? Is the TS 1086CZ 3.3V 1.5 A still available from you at your Portsmouth branch? Many thanks in anticipation, Richard

What is the input voltage of this device, as it states in your catalogue that the output voltage is 12V max., so where does the 3.3V come into it? Surely the input voltage should be 12V and the 3.3V should be the output. Please could you clarify.

Would this be suitable to step down power from a 5v USB, to 3V.
Asked by: STEVE
Yes the product does support that.
