PD-94491 PD-94491 200 Krad(Si) Low Dropout Linear Regulator Hermetic Package OMR9808SC OMR9808SC OMR9808SF OMR9808SF +5.0Vin to +3.3Vout @ 3.0A Product Summary Part Number OMR9808SC OMR9808SC OMR9808SF OMR9808SF Vin 5.0 V 5.0 V Vout 3.3V 3.3V IO 3.0A 3.0A Package MO-078AA MO-078AA 8-Lead Flatpack MO-078AA MO-078AA Features: The OMR9808 OMR9808 is a radiation hardened, 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 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. Total dose and low dose capabilitiy to 200 Krad(Si) allows use in space applications Ultra low dropout voltage of 0.4 volts significantly reduces power consumption Low noise, higher efficiency Remote shutdown permits power sequencing to be easily implemented Hermetic MO-078AA MO-078AA (TO-258AA) and 8lead flat pack ensure higher reliability K-level screened Absolute Maximum Ratings Symbol Parameter Value Units 3.5 +7.0 A V Io Vin Output Current Input Voltage PTOT Power Dissipation TC=25 o C 19 W Thermal Resistance, Junction to Case (MO-078AA MO-078AA) Thermal Resistance, Junction to Case (8 lead flatpack) 6.5 6.5 W/°C RTHJC RTHJC TJ TSTG TL www.irf.com Operating Junction Storage Temperature Range Lead Temperature W/°C -55 to +125 o -65 to +150 o 300 o C C C 1 6/5/02 OMR9808SC OMR9808SC, OMR9808SF OMR9808SF Electrical Characteristics @ TA= 25°C (Unless Otherwise Specified) Parameter Ou tpu t Vo ltage In pu t Vo ltage Ran geOp erating Line Reg ulation Co nd itions Vin= 5.0V, Io= 3.0A Io = 3.0A 4.75 Vin 5.25, Io= 3.0A 4.5 Vin 5.5, Io= 50mA Vin= 5.0V 10ma Io ut 3.0A Lo ad Reg ulation Dro po ut Voltag e Cu rrent Limit Vin= 5.0V, Overcurren t Latchu p F= 120 Hz., Vou t= Vref Vs h dn = 5V Is ou rce= 200u A Vin= 5.0, Io = 50mA , Sh dn = +5.0V Ripp le Rejectio n Sh utdo wn s o urce current Sh utdo wn Pin Th res h old Ou tpu t Vo ltage at Sh utdo wn Sy mbo l M in.

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 OMR9808SC OMR9808SC, OMR9808SF OMR9808SF Mechanical Outline MO-078AA 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 No Connection 1 2 3 4 5 Mechanical Outline 8-Lead Flat Pack Base: 1010-1018 C.R.S.
