Microchip Technology TC1305R-DVUN Dual Output LDO

The TC1305R-DVUN from Microchip Technology is a versatile and high-performance dual-output low dropout regulator (LDO) designed to cater to a wide range of applications requiring stable and reliable power supply. This advanced power management integrated circuit (PMIC) combines a fixed output, low-noise, high-PSRR (Power Supply Rejection Ratio) LDO with a selectable output voltage LDO, providing designers with a flexible solution for multi-voltage systems.

Key Features:

• Dual Independent LDOs: The TC1305R-DVUN features two LDO regulators that can supply up to 300 mA (LDO1) and 150 mA (LDO2) of output current, respectively. This makes it suitable for powering sensitive analog and digital circuits that require separate supply voltages.
• High PSRR: The device offers excellent power supply rejection ratio characteristics, minimizing noise and ripple from the input power source to ensure stable operation of the connected load.
• Low Dropout Voltage: With a low dropout voltage, the TC1305R-DVUN can maintain regulation with a minimal difference between the input and output voltages, improving efficiency and battery life in portable applications.
• Fixed and Adjustable Outputs: LDO1 provides a fixed output voltage, while LDO2 allows for an adjustable output voltage, giving designers the flexibility to set the desired voltage level according to the specific requirements of their application.
• Thermal and Overcurrent Protection: The device includes built-in thermal shutdown and current limit features to protect against over-temperature and overcurrent conditions, enhancing system reliability.
• Low Quiescent Current: The TC1305R-DVUN is designed for power-sensitive applications with its low quiescent current, which reduces power consumption when the device is in idle mode.
• Small Footprint: Available in a small 10-pin MSOP package, the TC1305R-DVUN is ideal for space-constrained applications.

Applications:

The TC1305R-DVUN is well-suited for a variety of applications, including but not limited to:

• Portable and battery-powered devices
• Wireless communication systems
• Microcontroller power supplies
• Handheld medical devices
• Audio and video equipment

With its dual-output configuration, high-performance specifications, and compact design, the Microchip TC1305R-DVUN is an excellent choice for powering multiple voltage rails in a single, integrated package.
