The TC1303B-AG0EMF is a high-performance, integrated power supply solution from the renowned Microchip Technology. This device combines a synchronous buck regulator (Switcher) with a linear regulator (LDO) to provide two regulated outputs. It is designed to maximize efficiency and minimize the footprint for power management in a variety of applications.

Key Features

• High-Efficiency Synchronous Buck Regulator: The Switcher operates at a fixed frequency and uses a PWM control scheme to ensure high efficiency across a wide range of loads.
• Independent Linear Regulator: The LDO can supply a separate output, which is ideal for powering noise-sensitive circuits due to its low dropout voltage and reduced noise characteristics.
• Adjustable Output Voltage: Both the Switcher and LDO outputs are adjustable, enabling a wide range of output voltages to accommodate various application requirements.
• Power Good Output: This feature provides a status signal indicating when the Switcher output is within regulation, which is useful for power sequencing and monitoring.
• Thermal Shutdown Protection: The device includes an over-temperature protection feature that shuts down the regulator to prevent damage from excessive heat.
• Overcurrent Protection: Both the Switcher and LDO are equipped with current limit protection to safeguard the device and the load from excessive current conditions.
• Small Package Size: The TC1303B-AG0EMF comes in a compact package, making it suitable for space-constrained applications.
