Overview
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 ±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.
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 TSOP−5 package.
