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 OMR9807SC OMR9807SF Vin Vout 5.0 V 2.5V 5.0 V 2.5V IO 3.0A 3.0A Package MO-078AA 8-Lead Flatpack MO-078AA Features: 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. 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 Value Units 3.5 +7.0 A V Io V in 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 Operating Junction -55 to +125 oC Storage Temperature Range -65 to +150 oC 300 oC RTHJC RTHJC TJ TSTG TL www.irf.com Lead Temperature °C/W 1 8/20/02 OMR9807SC, OMR9807SF Electrical Characteristics @ TA= 25°C (Unless Otherwise Specified) Parameter Output Voltage Input Voltage RangeLine Regulation Load Regulation Dropout Voltage Current Limit Ripple Rejection Shutdown source current Shutdown Pin Threshold Output Voltage at Shutdown Conditions Symbol Vin = 5.0V, Io = 3.0A Vout Io= 3.0A 4.75 ≤ Vin ≤ 5.25, Io= 3.0A Vline 4.5 ≤ Vin ≤ 5.5, Io= 50mA Vin= 5.0V Vload 10ma ≤ I o u t ≤ 3.0A Vdrop Vin= 5.0V, Overcurrent Ilatch Latchup F= 120 Hz., Vout= Vref Vshdn= 5V Ishdn Isource= 200uA Vshdn Vin= 5.0oV, Io= 50mA, Vout Shdn= +5.0V (shdn) Min. 2.475 4.5 -100 -5 -20 Typ. 2.5 Max 2.525 6.5 +100 +5 +20 Unit V V mV mV mV 0.4 V A 3.0 65 1.6 +0.1 dB uA V V Max 2.625 6.5 Unit V V 200 1.0 -0.1 Electrical Characteristics TA = -55 to +125°C Parameter Output Voltage Input Voltage RangeOperating Line Regulation Load Regulation Dropout Voltage Current Limit Ripple Rejection Shutdown source current Shutdown Pin Threshold Output Voltage at Shutdown Conditions Vin = 5.0V, Io = 3.0A Io= 3.0A Symbol Vout Min. 2.375 4.5 4.75 ≤ Vin ≤ 5.25, Io= 3.0A Vline -150 +150 mV 4.5≤ Vin ≤ 5.5, Io= 50mA Vin= 5.0V 10ma ≤ Iout ≤ 3.0A Vload -150 -150 +150 +150 mV mV Vdrop Ilatch 0.4 3.0 V A Vin= 5.0V, Overcurrent Latchup F= 120 Hz., Vout= Vref Vshdn= 5V Isource= 200uA Vin= 5.0oV, Io= 50mA, Shdn= +5.0V Typ. 2.5 65 Ishdn Vshdn Vout (shdn) 200 1.0 -0.1 1.6 +0.1 dB uA V V Simplified Schematic Vin Vout Drive Shutdown Gnd Ground 2 www.irf.com OMR9807SC, OMR9807SF OMR9807 Ripple Rejection vs. Frequency 3A 120 1.5A 100 .75A .50A (db) 80 60 40 20 0 100 1,000 10,000 100,000 1,000,000 Frequency (Hz) Vin Vout Vout Vin OMR9807 100uF 16V Tantalum SHDN 1.0uF Ceramic X7R GND 220uF 6.3V Tantalum Ground In order to maintain regulation and stability specified additional input and output bulk capacitors are recommended. 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 OMR9807SC, OMR9807SF 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.
