DESCRIPTION:
The MSK5502-12 and MSK5502-15 are high temperature linear voltage regulators capable of delivering 100mA of
output current at 232°C. Typical dropout is 1.7V with a 100mA load at 232°C. This device also has self-protection
features. Thermal protection will activate when junction temperature exceeds 275°C. Internal current limit protection will
limit the maximum current delivered to 200mA typical. The MSK5502-12 and MSK5502-15 are specifically design for
automotive, aeronautics and aerospace, and down-hole applications. The device is packaged in a hermetically sealed 12 pin
flat pack that is lead formed for surface mount applications.

APPLICATION NOTES
PIN FUNCTIONS
VIN - These pins provide the input power connection to the
MSK5502. All VIN pins must be connected for proper operation.
GND - These pins provide the VIN and VOUT ground reference. All GND pins must be connected for proper operation.
VOUT - These are the output pins for the device. All VOUT
pins must be connected for proper operation.
ENABLE - When tied low, the MSK5502 is enabled and oper-
ates normally. When tied high, the MSK5502 is disabled and
VOUT is connected to ground.
INPUT AND OUTPUT BYPASSING
The MSK5502 has an internal ceramic output capacitor,
which in most cases, is sufficient to stabilize the internal
control loop. Additional capacitance between 1 and 10uF
can be added. The output capacitor requires an ESR from
0.01 to 1Ω. Higher capacitor values improve load transient
response. Proper input bypassing is required in order to filter
out noise and provide low AC impedance source. The
MSK5502 has an internal ceramic input capacitor connected
between VIN and GND. In most applications the internal capacitor is sufficient for proper operation. Additional input
capacitance up to 1uF can be added to maximize transient
response and minimize power supply transients.
THERMAL LIMITING
The MSK5502 has an internal thermal shutdown feature.
The typical junction temperature threshold is 275°C with
10°C of hysteresis. When in thermal shutdown, the pass
transistor is disabled and VOUT is internally connected to
ground.
OVERCURRENT PROTECTION
The MSK5502 has an internal current limiter feature. The
typical current limit threshold is 200mA. In the case of short,
the MSK5502 may switch between current limit and thermal shutdown mode.
ENABLE FUNCTION
When the enable pin is tied low the MSK5502 is enabled and
operates normally. When the enable pin is tied high the
MSK5502 is disabled and VOUT is internally connected to
ground. The disable feature acts the same as the thermal
shutdown feature.
