1 M Rad (Si), ULTRA LOW DROPOUT POSITIVE LINEAR REGULATOR
+3.3Vin to +2.5V Output at 3.0A In Hermetic Packages
FEATURES * Total dose and low dose capability to 1M Rad (Si) allows use in space applications * Ultra low dropout voltage of 0.4V @ 3A out significantly reduces power consumption * Low noise, higher efficiency * Remote Shutdown permits power sequencing to be easily implemented * Hermetic MO-078AA (TO-258) and 8-lead flat pack ensure higher reliability * K-level screened DESCRIPTION The OMR9601 is a radiation hardened, ultra low dropout linear regulator designed specifically for space applications. This product has been characterized to a total ionizing dose of 1M Rad (Si) per MIL-STD-883, Method 1019, Condition A at both high and low dose rates under biased and unbiased conditions to account for ELDRE effects in bipolar devices. The ultra low dropout voltage of 0.4V @ 3A makes the part particularly useful for applications requiring low noise and higher efficiency.

In order to maintain regulation and stability specified additional input and output bulk capacitors are recommended. Capacitors recommended above should be low ESR tantalums with tolerances of 20% max. Internal to the product are a 4.7uF input capacitor and a 4.7uF output capacitor in parallel with a 0.33uF ceramic capacitor. Shutdown: The regulator can be shutdown by applying a voltage > 1.6V to pin 4. The regulator will restart when the SHDN pin is pulled below the shutdown threshold of 1.0V. If remote shutdown is not required, pin 4 should be connected to GND to insure a safe "off" state.
