OMR9604SC Datasheet | International Rectifier

Features : The OMR9604 is a radiation hardened, ultra low dropout adjustable linear regulator designed specifically for space applications. This product has been characterized to a total ionizing dose of 1 M 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 ELDRS 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. n Total dose and low dose capabilitiy to 1M Rad(Si) allows use in space applications n Ultra low dropout of 0.4 volt significantly reduces power consumption n Low noise, higher efficiency n Remote shutdown permits power sequencing to be easily implemented n Hermetic MO-078AA (TO-258AA) and 8- lead flat pack ensure higher reliability n K-level screened Absolute Maximum Ratings Symbol Io V in Vout PTOT RTHJC RTHJC TJ TSTG TL Parameter Output Current Input Voltage Output Voltage Range Power Dissipation TC=25 o C Thermal Resistance, Junction to Case (MO-078AA) Thermal Resistance, Junction to Case (8 lead flatpack) Operating Junction Storage Temperature Range Lead Temperature Value 3.5 +7.0 +1.26 to +3.2 19 6.5 6.5 -55 to +125 -65 to +150 300 Units °C/W °C/W o C o C o C .irf. 8/20/02 OMR9604SC, OMR9604SF Electrical Characteristics @ TA= 25°C (Unless Otherwise Specified) Parameter Input Voltage Range Operating Reference Voltage Line Regulation Load Regulation Dropout Voltage Current Limit Ripple Rejection Shutdown Source Current Shutdown Pin Threshold Output Voltage at Shutdown Conditions Io= 3.0A Symbol Vin Vref Vline Vload Vdrop Ilatch Ishdn Vshdn Vout (shdn) Min. 2.9 1.252 -100 -5 -20 Typ.
