Small Footprint
The Power Trends鈥?PT78ST200 is
a series of 3-terminal Integrated
Switching Regulators (ISRs) that can
supply up to 24 watts of regulated 12V
power. With a surge capability of 3
Amps and an output voltage that is
laser trimmed, it is ideal for inductive
load applications such as disk drive
motors.
