R1517 Series
36V Input 500mA Low Supply Current Voltage Regulator

Product Specifications

The R1517 Series are CMOS-based voltage regulators featuring 500mA output current and 36V input voltage. In addition to a fold-back protection circuit, a thermal shutdown circuit, built into conventional regulators, the R1517 contains a constant slope circuit and an auto-discharge function. Besides the low supply current by CMOS, the operating temperature is -40°C to 105°C and the maximum input voltage is 36V, the R1517 series are very suitable for power source of digital home appliances, office equipment and automotive applications.

R1517 Series for Consumer

APPLICATIONS

  • Power source for home appliances such as refrigerators, rice cookers, electric water warmers
  • Power source for notebook PCs, digital TVs, telephones, private LAN systems
  • Power source for office equipment such as copiers, printers, facsimiles, scanners, and projectors

PRODUCT LONGEVITY PROGRAM

R1517 series for consumer operate PRODUCT LONGEVITY PROGRAM.
This program has been introduced to help customers select the most appropriate part for applications that require long life cycles.


Operating Temperature Range : -40°C to 105°C


Set Output Voltage

The R1517 is available in five fixed output voltage options: 2.5 V, 3.3 V, 3.4 V, 5.0 V and 8.5 V. Contact our sales representatives for other voltages.
This regulator is also available in the adjustable output voltage version, R1517x001C, which allows output voltages that range from 2.5 V to 12 V via an external divider resistor.


SELECTION GUIDE

The output voltage, version, and package type for this device can be selected at the user’s request.
