Description

The SC4437 is a low power precision series bandgap

reference device. It accepts wide input voltage range V

OUT

+ 0.9V to 28V and generates stable output voltage with

superior accuracy and low drift over operating

temperatures. The SC4437 is ideal for battery powered

systems where there can be wide variations in supply

voltage and a need to minimize power dissipation.

The SC4437 is able to supply up to 20mA output current

with excellent line and load regulation characteristics.

The output compensation capacitor is optional. It

provides user the exibility of compact, low cost design

or further noise performance enhanced design.

The SC4437 is available in a compact 3-lead surface

mount SOT-23 package.
