PT79SR100 Series

-1.5 Amp Negative Step-Down

Integrated Switching Regulator

• High Efficiency > 85%

• Self-Contained Inductor

• Short Circuit Protection

• Over-Temperature Protection

The PT79SR100 is a line of

Negative Input/Negative Output

3-terminal Integrated Switching

Regulators (ISRs). These ISRs have a

maximum output current of -1.5 Amps

and an output voltage that is laser

trimmed to most industry standard volt-

ages. They have excellent line and load

regulation, and are ideal for applications,

such as RS232 and Ethernet communica-

tions, ECL logic, and op-amp circuitry.
