MSK5900RH

Manufacturer Part Number
MSK5900RH
Description
RAD TOLERANT ULTRA LOW DROPOUT ADJUSTABLE POSITIVE LINEAR REGULATOR
Manufacturer
MSK
Datasheet
MIL-PRF-38534 CERTIFIED
4707 Dey Road Liverpool, N.Y. 13088
FEATURES:
DESCRIPTION:
Typical dropout is only 0.30 volts with a 1.5 amp load. An external shutdown/reset function is ideal for power supply
sequencing. This device also has latching overload protection that requires no external current sense resistor. The
MSK 5900RH is specifically designed for many space/satellite applications. The device is packaged in a hermetically
sealed 12 pin flatpack that is lead formed for surface mount applications.
Total Dose Tested to 300K RAD (136 RADS(Si)/SEC)
Ultra Low Dropout for Reduced Power Consumption
External Shutdown/Reset Function
Latching Overload Protection
Adjustable Output Using Two External Resistors
