PD-94485A 200 Krad(Si) Ultra Low Dropout Linear Regulator Hermetic Package OMR9802SC OMR9802SF + 5.6Vin to +5.0Vout at 3.0A Product Summary Part Number OMR9802SC OMR9802SF Dropout I O Vin 0.4 V 3.0A 5.6V 0.4 V 3.0A 5.6V Vout 5.0V 5.0V Package MO-078AA 8-Lead Flatpack MO-078AA Features: The OMR9802 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. n Total dose and low dose capabilitiy to 200 Krad(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 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 Thermal Resistance, Junction to Case-8 lead flatpack 6.5 6.5 °C/W RTHJC RTHJC TJ TSTG TL www.irf.com °C/W Operating Junction -55 to +125 o C Storage Temperature Range -65 to +150 o 300 o C C Lead Temperature 1 8/20/02 OMR9802SC, OMR9802SF Electrical Characteristics @ TA= 25°C (Unless Otherwise Specified) Parameter Output Voltage Input Voltage RangeOperating Line Regulation Load Regulation Dropout Voltage Current Limit Ripple Rejection Shutdown source current Shutdown Pin Thres hold Output Voltage at Shutdown Conditions Vin= 5.6V, Io= 3.0A Io= 3.0A Symbol Vout Min. 4.95 5.4 5.45≤Vin ≤ 5.75, Io= 3.0A 5.1 ≤ Vin ≤ 6.0, Io= 50mA Vin= 5.6V 10ma ≤ Io ≤ 3.0A Io= 3.0A .

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 OMR9802SC, OMR9802SF 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 No Connection 1 2 3 4 5 Mechanical Outline 8-Lead Flat Pack Base: 1010-1018 C.R.S.
