DESCRIPTION:
The MSK5501 is an ultra low dropout, high temperature linear voltage regulator capable of delivering 100mA of output
current at 200°C. Typical dropout voltage is 71mV with a 100mA load. This is a voltage controlled device and drive current
does not increase with output current. The devise’s supply current is typically constant from no load to maximum load. This
device also has internal current limit protection. When the current limiting engages, the output voltage will decrease linearly
until the over current condition ends. The MSK5501 is specifically designed for automotive, aeronautics and aerospace, and
down-hole applications. The device is packaged in a hermetically sealed 5 pin SIP that is electrically isolated from internal
circuitry for direct heat sinking.

APPLICATION NOTES
PIN FUNCTION
VIN - This pin provides the input power connection to the
MSK5501.
GND - These pins provide the input and output ground reference.
VOUT - This pin is the output for the device.
ENABLE - When tied low, the MSK5501 is enabled and operates normally. When tied high, the MSK5501 is disabled.
INPUT AND OUTPUT POWER SUPPLY
BYPASSING
The MSK5501 has an internal output capacitor, which in
most cases, is sufficient to stabilize the internal control loop.
Additional capacitance can be added, and improves load transient response. Although not required, a 0.047μF ceramic
capacitor connected between VIN and GND, can be used to
maximize transient response and minimize power supply transients.
THERMAL LIMITING
TBD
OVER CURRENT PROTECTION
The MSK5501 has an internal current limiting feature. The
typical current limit threshold is 350mA. During an over
current event, the output voltage with be reduced linearly
until the over current state ends.
ENABLE FUNCTION
When the enable pin is tied low (< 0.9V), the MSK5501 is
enabled and operates normally. When the enable pin is tied
high (>1.7V), the MSK5501 is disabled and VOUT is floating.
Should the output voltage rise above VIN, or VIN drop below
the output voltage, an internal back diode will conduct reverse
current. Supply current, when disabled, is typically 1μA.
