MILPITAS, CA -- (Marketwired) -- 07/09/13 -- Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high-performance analog, mixed signal and power management semiconductors, today introduced the ISL75052SEH, a radiation hardened, single output LDO specified for an output current of up to 1.5A.
Designed for aerospace and satellite power applications, the ISL75052 is the industry's only SMD-approved LDO that is single event transient (SET) immune. It is high/low dose rate immune via wafer-by-wafer acceptance testing up to 100krad (Si) and 50krad (Si), respectively. Operating from an input voltage range of 4.0V to 13.2V (14.7V absolute maximum in-beam), the ISL75052SEH provides output voltages of 0.6V to 12.7V. Output voltage is adjustable based on an external resistor divider setting. Typical dropout voltage performance is 225mV at 1.5A, maximizing efficiency.
The ultra low dropout performance over temperature and radiation lets users reduce the voltage between the input and out voltage rails, saving significant power. The device's wide input voltage range of 4V to 13.2V allows designers to operate the part over a wide input voltage range, such as 12V, 5V or any in-between voltages. Output voltage accuracy of +/- 2 percent over radiation and over the military temperature range improves point-of-load (POL) input accuracy tolerance over varying AC/DC application conditions. The device's industry-best 160uA shutdown current, maximum, lengthens battery life when used in a redundant configuration. A PowerGood output pin is available for easy start-up configuration.
- SET mitigation with no added filters or diodes for LET of 86MeVcm2/mg reduces board space and system cost
- Wafer-by-wafer radiation guarantee means no upscreening, high product reliability
- Pin-for-pin drop-in to industry leading solutions
The ISL75052SEH is available now in an 18-lead ceramic flatpack, with prototype prices starting at $261.99 each. For more information visit: www.intersil.com/products/ISL75052SEH
