FAQs
What is SG6901ASZ?
The SG6901ASZ is a low dropout voltage regulator (LDO) designed by Sanken Electric Co., Ltd. It is ideal for applications requiring stable and reliable voltage regulation, such as power supplies for electronic devices, automotive electronics, and industrial systems.
How Does SG6901ASZ Work?
The SG6901ASZ works by regulating the input voltage to provide a steady and stable output voltage, even when the input voltage fluctuates. It employs a precision reference, error amplifier, and pass transistor to achieve voltage regulation with low dropout voltage, making it suitable for low voltage applications.
How Many Pins does SG6901ASZ have and What are the Functions of the Pinout Configuration?
The SG6901ASZ is housed in a 5-pin TO-220F package. The pinout configuration includes:
- VIN: Input voltage pin.
- GND: Ground pin.
- VOUT: Output voltage pin.
- NC: No connection pin.
- BYP: Bypass capacitor pin for noise reduction.
What are the Pros and Cons of SG6901ASZ?
Pros:
- Low Dropout Voltage: Provides stable output voltage even with a small input-output voltage differential.
- High Accuracy: Offers precise voltage regulation for sensitive electronic components.
- Thermal Shutdown Protection: Includes built-in thermal shutdown protection to prevent overheating.
- Wide Operating Temperature Range: Suitable for operation in harsh environmental conditions.
Cons:
- Fixed Output Voltage: May not be suitable for applications requiring variable output voltage.
- Package Size: The TO-220F package may be larger than other LDO regulators, requiring more board space.
Are There Any Equivalents/Alternatives to SG6901ASZ for Recommendation?
- The LM2940 from Texas Instruments is a comparable LDO regulator with similar features.
- Alternatives to the SG6901ASZ include the LT1086 from Analog Devices and the NCV4276 from ON Semiconductor.
