SAT8601  
Linear Voltage Regulator, 3A & 5A, Ultra- Low- Dropout, (ULDO)  
(Preliminary)  
FEATURES  
Ultra Low Dropout Voltage – 300mV @ 3.0A  
Compatible with industry standard OMR9600/IRUH Series  
Fixed and Adjustable versions  
K-level screening available  
Shutdown pin for output control  
Thermal Shutdown @ 150 deg. C  
MO-078 Package  
Optimized for operation at +3.3Vin or +5Vin  
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  
shutdown control and an ultra low drop out of 300mV @ 3A and 450mV at 5A. It is optimized  
for operation at +5V input or +3.3V input. Only one resistor is needed to set-up the output  
voltage in the adjustable configuration. The SAT8601 is well suited for low-noise high  
efficiency applications. The SAT8601 features fast transient response, which minimizes the size  
of required output capacitors. The internal capacitors used in the manufacturing of this device are  
in accordance with MIL-PRF-123 or MIL-PRF-55365.

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 +2.9V. 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  
+3.6V to +2.8V. The –55 will have peak performance at +4.5V to +5.5V. Input voltages outside of this  
range can affect short-circuit current and load current capability.
