PD-94490A 200 Krad(Si) Ultra Low Dropout Linear Regulator Hermetic Package OMR9807SC OMR9807SF +5.0Vin to +2.5Vout / 3.0A Product Summary Part Number Vin OMR9807SC 5.0 V OMR9807SF 5.0 V Vout 2.5V 2.5V IO 3.0A 3.0A Package MO-078AA 8-Lead Flatpack MO-078AA The OMR9807 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 200 Krad (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. Features: n Total dose and low dose capabilitiy to 200 Krad(Si) allows use in space applications n Ultra low dropout voltage of 0.4 volts sig- nificantly 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 Parameter Io Output Current Vin Input Voltage PTOT Power Dissipation TC=25 o C RTHJC Thermal Resistance, Junction to Case (MO-078AA) RTHJC Thermal Resistance, Junction to Case (8 lead flatpack) TJ Operating Junction TSTG Storage Temperature Range T L Lead Temperature Value 3.5 +7.0 19 6.5 6.5 -55 to +125 ...
