The ZLNB100X is a voltage regulator IC manufactured by Zetex Semiconductors (now Diodes Incorporated). It is a linear regulator designed for use in various power management applications. The ZLNB100X provides a stable and regulated output voltage, protecting downstream components from voltage fluctuations.

Applications

• Linear Power Supplies
• Battery-Powered Devices
• Microcontroller Power Supply
• Post-Regulation for Switching Regulators
• General Voltage Regulation

Features

• Low Dropout Voltage: Operates with a small difference between input and output voltage.
• Fixed Output Voltage: Provides a stable and precise output voltage.
• Overcurrent Protection: Protects against short circuits and overloads.
• Thermal Shutdown: Shuts down the regulator when the temperature exceeds safe limits.
• Small Package: Available in compact surface mount packages.

Benefits

• Stable Output Voltage: Provides a consistent and reliable voltage supply for sensitive components.
• Protection Against Damage: Overcurrent and thermal shutdown protect the regulator and the load from damage.
• Efficient Operation: Low dropout voltage minimizes power dissipation and improves efficiency.
• Compact Design: Small package allows for space-saving designs.
• Simplified Design: Requires few external components for operation.

Additional Details

The ZLNB100X typically has a fixed output voltage of 5V or 3.3V. The input voltage range is generally wide enough to accommodate various power sources. The low dropout voltage allows the regulator to operate effectively even when the input voltage is close to the output voltage. The overcurrent protection limits the output current in case of a short circuit or overload, preventing damage to the regulator and the load. It's commonly available in small surface mount packages like SOT-23. Diodes Incorporated ensures that this product meets industry standards for environmental compliance, such as RoHS.
