The PT78NR200 series creates
negative output voltage from a posi-
tive input voltage greater than 9V
These easy-to-use, 3-terminal, Inte-
grated Switching Regulators (ISRs)
have maximum output power of 10 to
12 watts and a negative output voltage
that is laser trimmed. They also have
excellent line and load regulation.
The PT78NR200 requires 100
LFM of airflow at its maximum
output current.
