Overview
The L78MR00 series, 500mA general-purpose voltage
regulator ICs provide reset output signal for microcomputers.
Features
• Reset function (power supply voltage monitor : Generates a reset signal at a power-on and temporal powerdown).
• Output voltage
L78MR05 : 5V (Reset output .......On-chip pull-up
resistor)
L78MR06 : 6V (Reset output .......Open collector)
L78MR08 : 8V (Reset output .......Open collector)
L78MR09 : 9V (Reset output .......Open collector)
L78MR12 : 12V (Reset output ....... Open collector)
• Output current ..........500mA
• On-chip ASO protector.
• On-chip thermal protector.
• On-chip overcurrent limiter.
• The use of package TO220-5H facilitates easy mounting
and thermal design.
• Delay time (td) may be set by an external capacitor.
