IRUH33P253B1M

PD-97041 Ultra Low Dropout Positive Fixed Linear Regulator IRUH33P253B1M +3.3Vin to +2.5Vout at 3.0A Product Summary Part Number IRUH33P253B1M Dropout 0.4V IO 3.0A Vin 3.3V Vout 2.5V MO-078AA Features: The IRUH33P253B1M 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 1.0 Mrad (Si) per MIL-STD-883, Method 1019, Condition D 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 to 1.0 Mrad (Si) and low dose n n n n n n n capability to 500 krad (Si) allows use in space applications Single Event latchup Immune LET = 84 MeV/(mg/cm2) Fluency = 1x109 ions/cm2 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 This part is also available in 8-Lead Flat Pack Package as IRUH33P253A1M Absolute Maximum Ratings Parameter Output Current Input Voltage Power Dissipation TC = 25°C Thermal Resistance, Junction to Case Operating Temperature Range Storage Temperature Range Lead Temperature Symbol IO Vin PTOT RTHJC TJ TS TL Value 3.5 7 19 6.5 -55 to +...
