The Power Trends’ PT5060 Series
is a dual output Integrated Switching
Regulator (ISR) designed for use in +5 volt
systems that require low power ±12 or ±15 volt
rails. They can be used to power such application circuits as D/A and A/D converters, Op
Amps, and interface logic. Both output voltages
can be easily adjusted with one external resistor.
These ISRs are offered in a low profile 12-pin
SIP package in either vertical or horizontal
through-hole or SMD-configurations.
Please note that this product does not
include short-circuit protection.
