IRUH50P333A1M

PD-97028 Ultra Low Dropout Fixed Positive Linear Regulator Product Summary Part Number IRUH50P333A1M IRUH50P333A1M +5.0Vin to +3.3Vout at 3.0A Dropout 0.4V IO 3.0A Vin 5.0V Vout 3.3V 8-LEAD FLAT PACK Features: The IRUH50P333A1M 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 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 n n n n n n n Total dose to 1.0 Mrad(Si) and low dose capability to 500 Krad(Si) allows use in space applications Single Event latchup Immune LET = 84 MeV/(mg/cm2) Fluency = 1 x 109 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 8-Lead Flat Pack ensures higher reliability Space Level Screened This part is also available in MO-078 Package as IRUH50P333B1M 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 7.0 19 6.5 -55 to +125 -65 to +150 300 Un...
