IRUH33PA13B20

PD-97029 Ultra Low Dropout Positive Adjustable Linear Regulator Product Summary Part Number IRUH33PA13B20 IRUH33PA13B20 +3.3Vin at 3.0A Dropout 0.4V IO 3.0A Vin 3.3V Vout 1.265V To (VIN - 0.4V) MO-078AA Features: The IRUH33PA13B20 is a space qualified, ultra low dropout linear regulator designed specifically for space applications. This product has been characterized to a total ionizing dose of 200Krad(Si) per MIL-STD-883, Method 1019 at 200Krad at high dose and 100Krad at 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 n n n n n Total dose to 200Krad(Si) and low dose capability to 30Krad(Si) allows use in space applications Low noise, higher efficiency Ultra low dropout voltage of 0.4V@ 3A out significantly reduces power consumption Remote shutdown permits power sequencing to be easily implemented Hermetic MO-078AA (TO-258AA) pack ensures higher reliability Space Level Screened Absolute Maximum Ratings Parameter Output Current Input Voltage Output Voltage Power Dissipation, TC = 25°C Thermal Resistance, Junction to Case Operating Temperature Range Storage Temperature Range Lead Temperature Symbol IO VIN VOUT PTOT RTHJC TJ TS TL Value 3.5 7.0 1.265V To (VIN - 0.4V) 19 8.5 -55 to +125 -65 to +150 300 Units A V W °C/W °C www.irf.com 1 03/22/06 www.DataSheet.in IRUH33PA13B...
