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.
