  • Wide Input Voltage Range
  • 85% Efficiency
  • Internal Over-T emperature Protection
  • Laser-trimmed Output Voltage
  • Soft Start The Power T rends’ PT5040 Series is a 3-terminal Integrated Switching Regulator (ISR) designed for use with +5 volt systems that require an addi- tional regulated +8 to +20 volts with up to 1A of output current. These ISRs are packaged in the 3 pin SIP configu- ration.
