Feature Benefit Bullets

Maximum Dropout Voltage: 1.5 V

A low dropout voltage allows the regulator to maintain a stable output voltage even with small differences between input and output voltages, making it suitable for battery-powered applications.

Operating Temperature (TJ-Max): 125 °C

This high maximum operating temperature enhances reliability and performance in demanding environments where heat dissipation is a concern.

Technology: BIPOLAR

Bipolar technology typically provides better noise performance and faster response times compared to some alternatives, making it ideal for sensitive applications.

Package Shape: ROUND

The round package shape can be advantageous for fitting into compact PCB layouts, optimizing space utilization while ensuring effective thermal management.

Terminal Form: THROUGH-HOLE

Through-hole terminals provide robust mechanical support and easy soldering, enhancing reliability in permanent connections.

Operating Temperature (TJ-Min): -40 °C

The wide operational temperature range ensures reliability in extreme environments, catering to applications in harsh conditions.

Packing Method: TR

Tape and reel packaging is convenient for automated assembly processes, minimizing production downtime and improving manufacturing efficiency.

Minimum Output Voltage: 5.39 V

This minimum output value guarantees that the regulator can deliver sufficient voltage for devices that require a stable 5.5 V supply, even under variable conditions.

Maximum Voltage Tolerance: 2 %

A maximum voltage tolerance of 2% ensures that the output remains stable and within acceptable limits, providing reliable performance in sensitive applications.

Nominal Output Voltage: 5.5 V

A fixed nominal output voltage simplifies design considerations by ensuring that connected devices receive the exact voltage they need for optimal performance.

No. of Terminals: 3

Having three terminals enables straightforward circuit integration while maintaining functionality and reducing the potential for layout errors.

Package Style (Meter): CYLINDRICAL

Cylindrical package style may have benefits in terms of space-saving arrangements and efficient thermal dissipation, enhancing overall performance.

Adjustability: FIXED

A fixed output makes it easier to implement without requiring additional components, reducing overall circuit complexity.

Terminal Pitch: 1.27 mm

A standard terminal pitch of 1.27 mm allows easy integration with most PCB designs and component layouts, enhancing compatibility.

Maximum Line Regulation: 0.02 %

Excellent line regulation indicates that the output voltage remains stable despite variations in input voltage, ensuring reliable operation.

Regulator Type: FIXED POSITIVE SINGLE OUTPUT LDO REGULATOR

This fixed positive single output design is ideal for powering devices requiring steady voltage without complex adjustments.

Terminal Finish: TIN

A tin terminal finish ensures good solderability and corrosion resistance, enhancing the longevity and reliability of connections.

Terminal Position: BOTTOM

Bottom terminal positioning allows efficient space usage on PCBs, facilitating more compact and effective designs.

Maximum Output Voltage: 5.61 V

The output voltage does not exceed 5.61 V, providing a safety margin for devices sensitive to overvoltage and ensuring reliable operation.

Maximum Load Regulation: 0.015 %

Exceptional load regulation ensures that output voltage remains stable with changes in load current, providing consistent performance for connected devices.

Minimum Input Voltage: 6.2 V

The minimum input voltage requirement ensures that the LDO operates efficiently, allowing for effective regulation and consistent output voltage.

Maximum Output Current: 0.1 A

A maximum output current rating of 0.1 A ensures that this regulator can sufficiently power low to medium current devices, making it versatile.

Nominal Dropout Voltage: 0.2 V

A nominal dropout voltage of just 0.2 V enables effective regulation even with minimal overhead, ideal for low voltage applications.

Maximum Input Voltage: 18 V

The high maximum input voltage provides flexibility in application, allowing use in a variety of power supply configurations.

Maximum Input Voltage Absolute: 20 V

The absolute maximum input voltage of 20 V offers a safety margin for spikes, helping to protect the device in case of unexpected surges.
