The NCP100 is a precision low voltage shunt regulator that is programmable over a voltage range of 0.9V to 6.0V. This device features a guaranteed reference accuracy of ±1.7% at 25°C and ±2.6% over the entire temperature range of -40°C to 85°C. The NCP100 exhibits a sharp low current turn-on characteristic with a low dynamic impedance of 0.20Ω over an operating current range of 100μA to 20mA. These characteristics make this device an ideal replacement for zener diodes in numerous application circuits that require a precise low voltage reference. When combined with an optocoupler, the NCP100 can be used as an error amplifier for controlling the feedback loop in isolated low output voltage (2.3V) switching power supplies. This device is available in an economical space saving TSOP-5 package.
