Sanken Electric Co STA801M Datasheet
●STA801M/802M
STA801M/802M
2-Output Separate Excitation Switching Type
■Features
• 2 regulators combined 1 package
• Compact inline package
• Output current (0.5A × 2 output)
• Output voltage of Ch2 selectable from 4 levels.
• Built-in flywheel diode (Schottky barrier diode)
• Requires only 7 external components (2 outputs)
• Phase correction and output voltage adjustment performed internally
• Built-in reference oscillator (125kHz) - Compact choke coil can be used
due to high frequency (compared to existing Sanken product)
• Built-in overcurrent and thermal protection circuits
• Built-in soft start circuit (Output ON/OFF control)
■Applications
• For BS and CS antenna power supplies
• For stabilization of the secondary stage of switching power supplies
• Electronic equipment
