Linear Technology LT1021
The LT1021 references are based on a buried zener diode structure that eliminates noise and stability problems associated with surface breakdown devices. The LT1021-7 uses no resistive divider to set output voltage, and therefore exhibits the best long term stability and temperature hysteresis. The LT1021-5 and LT102110 are intended for systems requiring a precise 5V or 10V reference with an initial tolerance as low as ±0.05%.| Part No. | LT1021 |
