Feature Benefit Bullets

Package Body Material: METAL

Metal body provides durability and protection, making it suitable for harsh environments or industrial applications.

Technology: BIPOLAR

Bipolar technology offers precision and stability in voltage regulation, ensuring reliable performance.

Maximum Voltage Tolerance: 4 %

Low voltage tolerance ensures accurate output voltage, important for sensitive electronic devices or circuits.

Nominal Output Voltage: 5 V

Stable output voltage of 5V is commonly used in many electronic applications, providing a consistent power source.

No. of Terminals: 3

Having 3 terminals simplifies installation and connection, making it easier to use for various projects.

Adjustability: FIXED

Fixed adjustability means the output voltage is preset and cannot be changed, which can be beneficial for applications that require a consistent voltage level.

Maximum Operating Temperature: 125 °C

High maximum operating temperature ensures the regulator can function reliably in hot environments without overheating.

Maximum Line Regulation: 0.05 %

Low line regulation ensures that the output voltage remains stable even with fluctuations in input voltage, ideal for precision applications.

Minimum Operating Temperature: 0 °C

Low minimum operating temperature allows the regulator to operate in cold conditions without performance issues.

Maximum Load Regulation: 0.1 %

Excellent load regulation ensures the output voltage remains constant regardless of the load, providing consistent power supply to connected devices.

Maximum Output Current: 1.5 A

High maximum output current of 1.5A allows the regulator to power multiple devices or components with ample capacity.

Nominal Dropout Voltage: 1.95 V

Nominal dropout voltage indicates the minimum voltage required for the regulator to operate effectively, ensuring reliable performance.

Maximum Input Voltage Absolute: 35 V

High maximum input voltage allows the regulator to handle a wide range of input voltages, making it versatile for different power sources.
