Description:The VRE310 series of low cost, zener-based precision Integrated Circuits provides ultra-stable +10V output with ±1.0mV (.01%) initial accuracy. This improvement in accuracy is made possible by a unique proprietary multipoint laser compensation technique. Significant improvements have been made in other performance parameters, including warm-up drift, line regulation, and long-term stability, to make this series the most accurate and stable available in an industry standard 8-pin SMT or DIP package.

Apex Microtechnology recommends a 4-layer PCB with a solid ground plane, and a thermal pad connected to a heat sink or a thermal via to ensure efficient heat dissipation. A minimum of 1 oz copper thickness is recommended for the PCB.
To ensure stable and accurate output voltage, it's essential to follow the recommended input and output capacitor values, and to decouple the input voltage with a 10uF capacitor. Additionally, the output voltage should be filtered with a 10uF capacitor and a 1kΩ resistor in series.
The maximum allowed input voltage ripple for the VRE310AS is 10% of the input voltage. Exceeding this limit may affect the regulator's performance and stability.
Yes, the VRE310AS is designed to meet the requirements of high-reliability and aerospace applications. However, it's essential to follow Apex Microtechnology's recommended screening and qualification process to ensure the device meets the specific requirements of the application.
The VRE310AS has built-in overcurrent protection, but it's still recommended to add external protection such as a fuse or a current-limiting resistor to prevent damage from excessive current. Additionally, a short-circuit protection diode can be added to prevent reverse voltage conditions.
