AN8003M

AN8003M Description

The AN8003M is a linear voltage regulator designed by Panasonic Electronic Components, offering a fixed output voltage of 3V and a maximum output current of 50mA. This regulator is housed in a 3HSIP package, making it suitable for surface-mount applications. It features a maximum input voltage of 20V and a quiescent current of just 1mA, ensuring efficient power consumption. The AN8003M boasts a high power supply rejection ratio (PSRR) of 70dB at 120Hz, which helps in maintaining a stable output voltage even under varying input conditions. The regulator is equipped with over-current protection, safeguarding it against potential damage from excessive current flow. Despite its obsolescence, the AN8003M remains a reliable choice for applications requiring a stable 3V supply with moderate current capabilities.

AN8003M Features

• Fixed Output Voltage: The AN8003M provides a stable 3V output, ideal for applications requiring a consistent power supply.
• High PSRR: With a PSRR of 70dB at 120Hz, the regulator effectively filters out noise from the input voltage, ensuring clean output power.
• Low Quiescent Current: Consuming only 1mA in quiescent mode, the AN8003M is highly efficient, making it suitable for low-power applications.
• Over-Current Protection: This feature protects the regulator from damage due to excessive current, enhancing its reliability and longevity.
• Surface Mount Compatibility: The 3HSIP package allows for easy integration into modern PCB designs, facilitating compact and efficient circuit layouts.
• Moisture Sensitivity Level (MSL): Rated at MSL 1 (Unlimited), the AN8003M is suitable for a wide range of manufacturing environments without the need for special handling.

AN8003M Applications

The AN8003M is well-suited for a variety of applications where a stable 3V supply is required. Its low quiescent current and high PSRR make it particularly useful in battery-powered devices and low-power electronics. Some specific use cases include:
