Zener Voltage Regulators

225 mW SOT–23 Surface Mount

This series of Zener diodes is offered in the convenient, surface

mount plastic SOT–23 package. These devices are designed to provide

voltage regulation with minimum space requirement. They are well

suited for applications such as cellular phones, hand held portables,

and high density PC boards.
