The MIC2214-GKBML-TR from Microchip Technology is a high-performance, dual linear voltage regulator designed for advanced portable electronic applications. This integrated circuit is specifically tailored to provide a reliable power management solution for devices that require dual power domains with low noise and high power supply rejection ratio (PSRR).

Key Features

• Dual Output: The MIC2214 offers two independent voltage regulators, making it ideal for systems that need to power different subsystems or components with separate voltage requirements.
• Low Dropout: With its low dropout voltage, the MIC2214 ensures efficient operation even when the input voltage is very close to the output voltage, thus maximizing battery life.
• High PSRR: A high PSRR of up to 70dB at 1kHz minimizes the impact of supply voltage variations on the output, providing a stable and clean power supply to sensitive RF and analog circuits.
• Low Noise: It features low output noise, which is critical for maintaining signal integrity in noise-sensitive applications such as audio and RF systems.
• Power Good Output: The MIC2214 includes a 'power good' output indicator, which can be used to monitor the status of the voltage regulator, ensuring that the system is operational only when stable power is available.
• Thermal Shutdown Protection: Built-in thermal shutdown protection safeguards the device and the system from damage due to overheating.
• Current Limit Protection: The current limit feature prevents damage by limiting the output current during overload conditions.

Applications

The MIC2214-GKBML-TR is well-suited for a wide range of applications, particularly those requiring high-quality power supplies, such as:

• Mobile phones and PDAs
• Portable media players
• Wireless LAN devices
• Handheld GPS units
• Portable instrumentation
