■Features
•2 regulators combined in one package
• Output current: 1.5A × 2 (HSOP 16 Pin
Surface mount package)
•High efficiency: TYP80% (SPI-8001TW),
TYP78% (SPI-8002TW)
•Variable output voltage: 1.0 to 16V (SPI-
8001TW), 1.0 to 24V (SPI-8002TW)
• Built-in reference oscillator (250kHz): Enables
to downsize a choke-coil
• Low circuit current consumption: ≤ 1µA (at
output OFF)
• High accuracy reference voltage: ±1%
• Built-in foldback-overcurrent and thermal
protection circuits
• Built-in ON/OFF circuit (soft start available) –
per output
*1: Absolute maximum ratings show the destructive limit. No parameter should exceed the ratings in transient or normal
operations.
*2: When mounted on glass-epoxy board 70cm2 (copper laminate area 30.8cm2).
*3: Limited by thermal protection.
