PD-94479A 1 M Rad(Si) Ultra Low Dropout OMR9605SC Adjustable Linear Regulator OMR9605SF Hermetic Package + 5.0Vin /+4.0 to +5.1Vout at 3.0A Product Summary Part Number OMR9605SC OMR9605SF Dropout 0.4 V 0.4 V IO 3.0A 3.0A V in 5.0V 5.0V Package MO-078AA 8-Lead Flatpack MO-078AA Features: The OMR9605 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 voltage of 0.4 volt signifi cantly 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 +4.1 to +5.1 19 6.5 6.5 -55 to +125 -65 to +150 300 Units A V V W °C/W °C/W oC oC oC www.irf.com 1 8/20/02 OMR9605SC, OMR9605SF Electrical Characteristics @ TA= 25°C (Unless Otherwise Specified) Parameter Input Voltage RangeO perating Reference Voltage Line Regulation Conditions Io= 3.0A Symbol Min. 4.5 1.252 -100 -5 -20 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. 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. www.irf.com 3 OMR9605SC, OMR9605SF Mechanical Outline MO-078AA Base: GLIDCOP Pins: Copper core, Alloy 52 Seals: G lass Base Pin Connections Terminal Description 1 Vin 2 GND 3 Vout 4 Shutdown 5 Adjust 12345 Mechanical Outline 8-Lead Flat Pack Base: 1010-1018 C.R.S.
