The PT78NR100 Series creates a
negative output voltage from a posi-
tive input voltage greater than 7V.
These easy-to-use, 3-terminal, Inte-
grated Switching Regulators (ISRs)
have maximum output power of 5
watts and a negative output voltage
that is laser trimmed. They also have
excellent line and load regulation.

Notes:
(1) The PT78NR100 Series requires a 100F electrolytic or tantalum capacitor at both the input and output for proper operation in all applications. The input
capacitor, C1 must have a ripple current rating ≥600 mArms, and an ESR ≤0.2.
(2) The ISR will operate down to no load with reduced specifications.
(3) See Thermal Derating chart.
