IRUH50PA23B20

PD-97030 Ultra Low Dropout Positive Adjustable Linear Regulator Product Summary Part Number IRUH50PA23B20 IRUH50PA23B20 +5.0Vin at 3.0A Dropout 0.4V IO 3.0A Vin 5.0V Vout 1.265V To (VIN - 0.4V) MO-078AA Features: The IRUH50PA23B20 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 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 Total dose to 200 Krad(Si) and low dose capability to 200 Krad(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 6.5 -55 to +125 -65 to +150 300 Units A V W °C/W °C www.irf.com 1 04/08/08 www.DataSheet.in IRUH50PA23B20 Pre-Radiation ...
