1-1-1 Linear Regulator ICs
SI-3000KS Series Surface-Mount, Low Current Consumption, Low Dropout Voltage Linear Regulator ICs
■Features
• Compact surface-mount package (SOP8)
• Output current: 1.0 A
• Compatible with low ESR capacitor
• Low circuit current at output OFF Iq ≤ 350 µA
(IO = 0 A, VC = 2 V)
• Low current consumption Iq (OFF) ≤ 1 µA (VC
= 0 V)
• Low dropout voltage VDIF ≤ 0.6 V (IO = 1 A)
• 3 types of output voltages (2.5 V, 3.3 V, and
variable type) available
• Output ON/OFF control terminal voltage
compatible with LS-TTL
• Built-in drooping-type-overcurrent and thermal
protection circuits

*1: VIN (max) and IO (max) are restricted by the relation PD = (VIN - VO) × IO. Please calculate these values referring to the
Copper laminate area vs. Power dissipation data as shown hereinafter.
*2: When mounted on a glass epoxy board of 1600 mm² (copper laminate area 2%).

*1: Refer to the Dropout Voltage parameter.
*2: The Is1 is specified at the 5% drop point of output voltage VO on the condition that VIN = VO + 1 V, and IO = 10 mA.
*3: Output is OFF when the output control terminal VC is open. Each input level is equivalent to LS-TTL level. Therefore, the device can be driven directly by LS-TTLs.
