US8072724B2 Over-voltage protection circuit - Google Patents

OVERVOLTAGE PROTECTION An important feature on many power supplies is over voltage protection on the output. This is particular important for 5 volt supplies which are used to power TTL logic circuits. These TTL circuits have an absolute maximum supply voltage of 7.0V so that if, due to an internal fault condition, the power supply output voltage were to rise above this voltage, all of the
