Voltage Reference, Adjustable, Fairchild Semiconductor


For low power, low current applications, the shunt regulators from Fairchild Semiconductor feature adjustable/programmable output voltages with superb thermal stability. The shunt regulators provide low dynamic output impedance and fast turn-on response while operating over the industrial temperature range.

For these non-cancellable (NC), and non-returnable (NR) products, Terms and Conditions apply.
