- Input Voltage Range: 2.5V to 6.0V
- Output Voltage: Adjustable (0.8V to 5.0V) or fixed options
- Output Current: Up to 3A
- Low Dropout Voltage: 200mV (typical at 3A)
- High Accuracy: ±1% output voltage tolerance
- Low Quiescent Current: 65μA (typical)
- Protections: Overcurrent, overtemperature, and reverse current protection
- Package: DFN-8 (3x3mm) for efficient thermal performance
- Applications: Power supplies for FPGAs, ASICs, and processors
Compact, efficient, and reliable, the BL3085B is ideal for space-constrained, high-current applications.

The BL3085B is a 5-pin voltage regulator IC with the following pin functions:
1. VIN (Input Voltage): Receives the input power supply.
2. GND (Ground): Common ground reference.
3. EN (Enable): Controls the regulator's on/off state (high = on, low = off).
4. FB (Feedback): Adjusts output voltage via external resistors.
5. VOUT (Output Voltage): Provides the regulated output.
It typically operates as a step-down (buck) converter, delivering stable DC output from a higher input voltage. The exact specifications (e.g., voltage range, current) depend on the manufacturer's datasheet.

The BL3085B is a high-performance DC-DC converter module commonly used in:
1. Telecommunications – Powering base stations and network equipment.
2. Industrial Automation – Providing stable voltage for PLCs, sensors, and control systems.
3. Medical Devices – Ensuring reliable power in diagnostic and monitoring equipment.
4. Railway Systems – Supporting onboard electronics and signaling devices.
5. Renewable Energy – Integrating with solar/wind power inverters and storage systems.
6. Data Centers – Powering servers and networking hardware efficiently.
Its compact design, wide input range, and high efficiency make it suitable for demanding applications.

The BL3085B is typically available in a SOT-23-5 package, a compact surface-mount type with 5 pins. This package is widely used for low-power voltage regulators and other small ICs due to its small footprint and efficient thermal performance. For precise details, always refer to the manufacturer's datasheet.
