NTE7080
Integrated Circuit
Precision Voltage Reference Diode,
1.235V
Description:
The NTE7080 is a micropower two–terminal band–gap voltage regulator diode in a TO92 type package. This device features exceptionally low dynamic impedance, low noise, and stable operation over
time and temperature. Tight voltage tolerances are achieved by on–chip trimming. The large dynamic operating range enables this device to be used in applications with widely varying supplies with excellent regulation. Extremely low operating current make the NTE7080 ideal for micropower circuitry
like portable instrumentation, regulators, and other analog circuitry where extended battery life is required.
