NCP100/D
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 over an operating current range of 100 A 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.
