OMR9601
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.
