The TCR2EE39,LPVT is a low-dropout (LDO) linear regulator manufactured by Toshiba Semiconductor and Storage. This regulator provides a stable and accurate 3.9V output voltage, even when the input voltage is close to the output. Its key characteristics include a low dropout voltage, which ensures efficient operation even with a small voltage difference between input and output, and a low quiescent current, which helps to minimize power consumption in battery-powered applications. The LPVT in the name refers to the package type.

Applications:

• Power management in portable devices (smartphones, tablets)
• Battery-powered IoT (Internet of Things) devices
• Microcontroller power supplies
• Sensor power supplies requiring a stable 3.9V source
• Wireless communication modules

Features:

• Fixed 3.9V output voltage
• Low dropout voltage, enabling operation with small input-output voltage differentials
• Low quiescent current for efficient power consumption
• Overcurrent protection to prevent damage from excessive load
• Thermal shutdown protection to prevent overheating
• Stable with ceramic capacitors, simplifying design and reducing component count
• Small LPVT (Leadless Plastic Very Thin) package for space-saving

Benefits:

• Extended battery life: The low quiescent current minimizes power drain, allowing for longer runtimes in battery-operated devices.
• Stable and reliable power: Provides a consistent 3.9V output, ensuring stable operation of connected components.
• Protection against faults: Overcurrent and thermal shutdown features safeguard the regulator and connected circuitry.
• Space-saving design: The small LPVT package allows for integration in compact electronic devices.
• Simplified application: Stable operation with ceramic capacitors reduces the need for complex external circuitry.

Additional Details:

The TCR2EE39,LPVT is designed for use in a wide range of applications where a stable 3.9V supply is needed. It's particularly well-suited for portable and battery-powered devices due to its low power consumption and small size. The LPVT package is a leadless, very thin package, which contributes to the overall miniaturization of electronic devices.
