Microchip Technology has announced a commercial-off-the-shelf (COTS) rad-tolerant power device with the MIC69303RT 3A Low-Dropout (LDO) Voltage Regulator. The new high-current, low-voltage MIC69303RT is a power management solution targeting LEO and other space applications. The commercialization of the Low-Earth Orbit (LEO) region is transforming space exploration and satellite communication. It is essential to select components that can withstand the harsh space environment. Additionally, the power device is available for prototype sampling in both plastic and hermetic ceramic.
The MIC69303RT is based on proven COTS devices making it easier to conduct a preliminary evaluation and early development. Operating from a single low voltage supply of 1.65 to 5.5 volts, the device can supply output voltages as low as 0.5V at high currents. Moreover, it offers high precision and ultra-low dropout voltages of 500 mV under extreme conditions.
“MIC69303RT is Microchip’s first rad-tolerant power management device with a hermetic ceramic package, latch up immunity and 50 Krad total dose robustness,” said Bob Vampola, vice president of Microchip’s aerospace and defense business unit.
“This COTS rad-tolerant power management device enables new design possibilities in space applications,” said Keith Pazul, director of marketing for Microchip’s analog power and interface business unit. “Customers can design their space system with confidence by selecting the COTS MIC69303RT.”
Features:
Designed for harsh aerospace applications, the MIC69303RT is operational in temperature ranges from -55°C to +125°C. Moreover, it is offered in 8-pin and 10-pin package configurations with radiation tolerance up to 50 Krad. The low noise is critical to sensitive RF circuits, post-regulation of switching power supplies and industrial power applications.
It is manufactured in compliance with MIL Class Q or Class V requirements: screening testing, qualification testing and TCI/QCI specifications.
Development Tools
The MIC69303RT Plastic Evaluation Board is designed to evaluate the performance of the plastic engineering IC version for the MIC69303RT. Additionally, the 4-layer PCB allows the user to easily change and measure the electric parameters of the device at different input and output conditions.
Pricing and Availability
The MIC69303RT is available in limited sampling upon request. Meanwhile, for additional information, contact a Microchip sales representative.
