PD-94489A 200 Krad(Si) Ultra Low Dropout OMR9806SC Adjustable Linear Regulator OMR9806SF Hermetic Package +7.5Vin / +6.1 to +7.0Vout @ 3.0A Product Summary Part Number OMR9806SC OMR9806SF Dropout I O 0.4 V 3.0A 0.4 V 3.0A V in 7.5V 7.5V Package MO-078AA 8-Lead Flatpack MO-078AA Features: The OMR9806 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 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. n Total dose and low dose capabilitiy to 200 Krad(Si) allows use in space applications n Ultra low dropout voltage of 0.4V@ 3A out 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 Parameter Value Units 3.5 +8.0 +6.1 to +7.0 A V V Io Vin Vout Output Current Input Voltage Output Voltage Range PTOT Power Dissipation TC=25 o C 19 W Thermal Resistance, Junction to Case (MO-078AA) Thermal Resistance, Junction to Case (8 lead flatpack) 6.5 6.5 °C/W RTHJC RTHJC TJ TSTG TL www.irf.com Operating Junction Storage Temperature Range Lead Temperature °C/W -55 to +125 o -65 to +150 o 300 o C C C 1 8/20/02 OMR9806SC, OMR9806SF Electrical Characteristics @ TA= 25°C (Unless Otherwise Specified) Parameter Input Voltage RangeOperating Reference Voltage Line Regulation Load Regulation Dropout Voltage Current Limit Ripple Rejection Shutdown s ource current Shutdown Pin Thres hold Output Voltage at Shutdown Conditions Io= 3.0A Symbol Min. 6.5 Typ.

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. www.irf.com 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 shold be connected to GND to insure a safe “off” state. 3 OMR9806SC, OMR9806SF Mechanical Outline MO-078AA Base: GLIDCOP Pins: Copper core, Alloy 52 Seals: Glass Base Pin Connections Terminal Description 1 Vin 2 GND 3 Vout 4 Shutdown 5 Adjust 1 2 3 4 5 Mechanical Outline 8-Lead Flat Pack Base: 1010-1018 C.R.S.
