SI-3000ZF Datasheet, PDF (1/2 Pages) Sanken electric – 5-Terminal, Low Dropout Voltage

1-1-4 Linear Regulator ICs
SI-3000ZF Series 5-Terminal, Low Dropout Voltage
■Features
• Compact full-mold package (equivalent to
TO220)
• Output current: 3.0A
• Low dropout voltage: VDIF ≤ 0.7V (at IO = 3.0A)
• Low circuit current at output OFF: Iq (OFF) ≤ 1µA
• Built-in overcurrent and thermal protection circuits
■Applications
• Secondary stabilized power supply (local
power supply)

*1: VIN (max) and IO (max) are restricted by the relationship PD = (VIN - VO) × IO.
*2: Set the input voltage to 2.4V or higher when setting the output voltage to 2.0V or lower.

*1: Set the input voltage to 2.4V or higher when setting the output voltage to 2.0V or lower.
*2: IS1 is specified at the 5% drop point of output voltage VO under the Output Voltage parameter conditions.
*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.
*4: These products cannot be used in the following applications because the built-in foldback-type overcurrent protection may cause errors during start-up stage.
(1) Constant current load (2) Positive and negative power supply (3) Series-connected power supply (4) VO adjustment by raising ground voltage
