DESCRIPTION:
The MSK 5500-15 is a low power voltage regulator/reference capable of delivering 50mA of output current at 232°C.
Typical dropout is 0.450 volts with a 10mA load at 232°C. An external shutdown function is ideal for power supply
sequencing. This device also has short circuit protection that requires no external current sense resistor. The MSK 550015 is specifically designed for automotive, aeronautics and aerospace, and down-hole applications. The device is packaged
in a hermetically sealed 12 pin flatpack that is formed for surface mount applicatins.

APPLICATION NOTES
PIN FUNCTIONS
VIN - These pins provide the input power connection to the MSK
5500-15.
GND - These pins provide the input and output ground reference.
VOUT - These are the output pins for the device. All three pins
must be connected for proper operation.
SHDN - This pin is used to disable the output and is logic low.
INPUT AND OUTPUT BYPASSING
Proper input bypassing is required in order to filter out noise and
provide low AC impedance source. The MSK 5500-15 has an
internal 0.1uF ceramic capacitor connected between VIN and GND.
In most application the internal input capacitor will be sufficient
for proper operation. Additional input capacitance can be added
to maximize transient response and minimize power supply transients. For stability the MSK 5500-15 has an internal 0.2uF low
ESR capacitor connected between VOUT and GND. To improve
transient response additional capacitance up to 4.7uF can be
added if needed.
THERMAL LIMITING
The MSK 5500-15 has no internal thermal shutdown feature.
Operation above 232°C is possible at the expensive of reducing
product lifetime.
START UP OPTIONS
The MSK 5500-15 has been designed to provide a soft-start
with little to no overshoot. If slight overshoot is observed when
turning on into a light load adding output capacitance will eliminate the overshoot.
OVERCURRENT PROTECTION
The MSK 5500-15 has a short circuit protection feature it is,
however, not able to sink current. Doing so could damage the
regulator.
SHUTDOWN
The MSK 5500-15 has a shut-down feature that will set the
output of the regulator to high impedance. The feature helps reduce power consumption by 90% in power-critical applications.
A voltage lower then 0.6V on the SHDN pin will put the regulator into shut-down mode. A voltage of greater than 2.3V on the
SHDN pin will turn the regulator on.
