This document describes the features and characteristics of the SI-3000F series products, including compact full-mold package, output current of 1.0A, low dropout voltage, etc. It also provides various applications and absolute maximum ratings.
The document describes the Sanken SI-3000F Series, which includes models such as the SI-3050F, SI-3090F, SI-3120F, SI-3150F, SI-3157F, and SI-3240F. These are 5-terminal, multi-function, full-mold low dropout voltage dropper type regulators designed for compact applications equivalent to a T0220 package.
The series features built-in foldback overcurrent protection, overvoltage protection, and thermal protection circuits. It supports variable output voltage (rise only) with an output current of 1.0A and a low dropout voltage of approximately 1V at full load. A specific variant, the SI-3025F, offers a fixed output voltage type.
| Output Current | 1.0A |
|---|---|
| Low Dropout Voltage | Approx. 1V (at Io=1.0A) |
| Package Type | Full-Mold (equivalent to T0220) |
| Junction Temperature Range | -40 to +125 °C |
| Ambient Operating Temperature | -30 to +100 °C |
| Thermal Resistance (Junction to Case) | 7.0 °C/W |
The output current is rated at 1.0A.
No, the SI-3025F is a fixed output voltage type, while other models in the series offer variable output.
The device includes foldback overcurrent, overvoltage, and thermal protection circuits.
