IS2-1009EH-Q - Renesas Electronics

Description: The Star*Power™ Radiation Hardened IS-1009RH, IS-1009EH are a 2. 5V shunt regulator diode is designed to provide a stable 2. 5V reference over a wide current range. These devices are designed to maintain stability over the full military temperature range and over time. The 0. 2% reference tolerance is achieved by on-chip trimming. An adjustment terminal is provided to allow for the calibration of system errors. The use of this terminal to adjust the reference voltage does not effect the temperature coeffici

IS2-1009EH-Q Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (AN1844) for the IS2-1009EH-Q, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
  • The IS2-1009EH-Q has an internal overcurrent protection (OCP) feature that can be enabled by setting the OCP threshold through the I2C interface. Additionally, external OCP circuits can be implemented using resistors and comparators to provide an additional layer of protection.
  • Renesas recommends using a 10uF to 22uF ceramic capacitor with an X7R or X5R dielectric as the input capacitor for the IS2-1009EH-Q. The capacitor value and type may vary depending on the specific application and input voltage ripple requirements.
  • The IS2-1009EH-Q output voltage can be configured through the I2C interface by writing to the voltage control register. The output voltage range is from 0.6V to 3.3V, and the voltage step size is 10mV. Refer to the datasheet for the specific register settings and voltage calculation formula.
  • The maximum ambient temperature for the IS2-1009EH-Q is 85°C, with a derating of 1.5mA per °C above 60°C. It's essential to ensure proper thermal design and heat dissipation to maintain reliable operation within the specified temperature range.
