Microchip Technology has launched the MIC69303RT 3A Low-Dropout Voltage Regulator, a radiation-tolerant power management device for space application developers. This high-current, low-voltage device targets low-Earth orbit (LEO) space applications.

The MIC69303RT operates from a single low-voltage supply of 1.65 v to 5.5 v and can supply output voltages as low as 0.5 v at high currents. It offers high-precision and low dropout voltages of 500 mv under extreme conditions. The MIC69303RT is a companion power source solution for Microchip’s microcontrollers, such as the SAM71Q21RT and PolarFire field-programmable gate arrays.

This device is designed for harsh aerospace applications and remains operational in temperature ranges from -55 C to +125 C. It is offered in 8-pin and 10-pin package configurations with radiation tolerance up to 50 krad.

Additionally, the MIC69303RT is manufactured in compliance with MIL Class Q or Class V requirements, including screen testing, qualification testing and more.

The MIC69303RT is available for prototype sampling in both plastic and hermetic ceramic. The plastic MIC69303RT is compliant with high-reliability plastic quality flow derived from AEC-Q100 automotive requirements with specific additional tests necessary for space applications.

This device is available in limited sampling upon request.
