The SC4437 is a low power precision series bandgap reference device. It accepts wide input voltage range VOUT + 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.
