NCP100 Sub 1.0 V Precision Adjustable Shunt Regulator
The NCP100 is a precision low voltage shunt regulator that is programmable over a voltage range of 0.9 V to 6.0 V. This device features a guaranteed reference accuracy of ฑ1.7% at 25ฐC and ฑ2.6% over the entire temperature range of ญ40ฐC to 85ฐC. The NCP100 exhibits a sharp low current turnญon characteristic with a low dynamic impedance of 0.20 W over an operating current range of 100 mA to 20 mA. 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 (2.3 V) switching power supplies. This device is available in an economical space saving TSOPญ5 package.
