3-A Rad-hard LDO regulator delivers high performance
The ISL75051SRH is an SMD-approved single output, ultra-low dropout linear regulator that is immune to high dose radiation up to 100 krads (Si), and to single event effects without the need for additional diodes or filters, reducing board space and system cost. Dropout voltage is an ultra-low 65 mV at 1 A, and 225 mV at 3 A, permitting increased efficiency and battery life. They operate over an input voltage range of 2.2 V to 6.0 V and can provide output voltages of 0.8 V to 5.0 V.
The ISL75051SRH is suitable for DSP, FPGA and microprocessor core power supplies, post-regulation of switch mode power supplies and down-hole oilfield drilling equipment.
DLA SMD approval means no need for up-screening and no acceptance testing, saving designers’ time and cost. The device’s 1u A shutdown current extends battery life in redundant configurations.
