Fixed and Adjustable versions
Shutdown pin for output control
Thermal Shutdown @ 150 deg. C
Optimized for operation at +3.3Vin or +5Vin
MO-078 Package
DESCRIPTION
The SAT8601 is a military qualified, ultra low dropout linear regulator designed for high
reliability applications. Assembled in a hermetic MO-078 package, the SAT8601 provides an
ultra low drop out voltage of 300mV @ 3A and 450mV at 5A. The SAT8601 is optimized for
operation at +5V input or +3.3V input. The internal capacitors used in the manufacturing of this
device are in accordance with MIL-PRF-123 or MIL-PRF-55365. The components are de-rated
per SatCon’s Class-K requirements.

Notes:
1. Shutdown pin voltage must be > 2.0V to initiate output inhibit. Pin should be grounded if not used.
2. Voltage dropout is dependent on a minimum input Voltage of +2.8V. Specification applies only to output
voltages of +2.5V or greater. Output Voltages below 2.5V will have a greater minimum dropout
requirement.
3. The SAT8601 is optimized for specific Input Voltage ranges. The –53 will have peak performance at
+2.8V to +3.6V. The –55 will have peak performance at +4.5V to +5.5V. Input voltages outside of this
range can affect short-circuit current, load current capability and create electrical overstress to internal
components.
