IRUH33P253A1M

PD-97042 Ultra Low Dropout Positive Fixed Linear Regulator IRUH33P253A1M +3.3Vin to +2.5Vout at 3.0A Product Summary Part Number Dropout IO Vin Vout IRUH33P253A1M 0.4V 3.0A 3.3V 2.5V 8-LEAD FLAT PACK The IRUH33P253A1M 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. Features: n Total dose to 1.0 Mrad (Si) and low dose capability to 500 krad (Si) allows use in space applications n Single Event latchup Immune LET= 84 MeV/(mg/cm2) Fluency = 1x109 ions/cm2 n Low noise, higher efficiency n Ultra low dropout voltage of 0.4V@ 3A out significantly reduces power consumption n Remote shutdown permits power sequencing to be easily implemented n Hermetic 8-lead flat pack ensures higher reliability n Space Level Screened n This part is also available in MO-078 Package as IRUH33P253B1M 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 +125 -65...
