LE25CZ  

Linear & Switching Voltage Regulators

LE25CZ Description

The LE25CZ is a linear voltage regulator designed by STMicroelectronics, offering a fixed output voltage of 2.5V and a maximum output current of 100mA. This regulator is housed in a TO92-3 package, making it suitable for through-hole mounting. Despite being marked as obsolete, the LE25CZ continues to be a reliable choice for applications requiring a stable power supply with minimal dropout voltage. The device features a maximum input voltage of 18V and a dropout voltage of only 0.5V at 100mA, ensuring efficient operation even at low input-to-output differentials. The regulator also includes over-current and over-temperature protection, enhancing its reliability and robustness in various operating conditions.

LE25CZ Features

• Fixed Output Voltage: The LE25CZ provides a stable 2.5V output, ideal for applications requiring a precise and consistent power supply.
• Low Dropout Voltage: With a maximum dropout voltage of 0.5V at 100mA, the regulator maintains high efficiency even when the input voltage is close to the output voltage.
• Over-Current and Over-Temperature Protection: These features ensure the regulator can handle transient overloads and high temperatures without damage, enhancing its durability and reliability.
• Low Quiescent Current: The regulator operates with a quiescent current of only 1mA, minimizing power consumption in standby or low-load conditions.
• High Power Supply Rejection Ratio (PSRR): The PSRR ranges from 82dB at 120Hz to 60dB at 10kHz, effectively filtering out noise and ripple from the input power supply.
• Compliance and Packaging: The LE25CZ is REACH unaffected and RoHS3 compliant, ensuring it meets environmental and safety standards. It is available in bulk packaging, suitable for large-scale production.

LE25CZ Applications

The LE25CZ is well-suited for a variety of applications where a stable and efficient power supply is crucial. Some specific use cases include:

• Consumer Electronics: Ideal for powering low-power devices such as portable audio equipment, handheld gaming consoles, and small appliances.
• Industrial Control Systems: Provides a reliable power source for sensors, microcontrollers, and other low-power components in industrial automation and control systems.
• Medical Devices: Suitable for powering low-power medical instruments and diagnostic equipment, where stability and precision are paramount.
• Telecommunications: Can be used in low-power communication modules and IoT devices, ensuring stable operation and minimal power loss.

Conclusion of LE25CZ

The LE25CZ, despite being marked as obsolete, remains a robust and reliable linear voltage regulator for applications requiring a stable 2.5V output and efficient power management. Its low dropout voltage, over-current and over-temperature protection, and high PSRR make it a superior choice over similar models. The regulator's compliance with environmental and safety standards ensures it meets the demands of modern electronics manufacturing. While newer alternatives may be available, the LE25CZ continues to offer a cost-effective and reliable solution for a wide range of applications in consumer electronics, industrial control systems, medical devices, and telecommunications.
