PT78NR100 Series

1 Amp Plus to Minus Voltage

Integrated Switching Regulator

SLTS058B

(Revised 8/31/2000)

• Negative output from positive input

• Wide Input Range

• Self-Contained Inductor

• Short Circuit Protection

• Over-Temperature Protection

• Fast Transient Response

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 100µF electrolytic or tantalum capacitor at both the input and output for proper operation in all applications. The input

capacitor, C₁must have a ripple current rating ≥600 mArms, and an ESR ≤0.2Ω.

(2) The ISR will operate down to no load with reduced specifications.

(3) See Thermal Derating chart.
