The MIC2214-FMBML-TR is a highly efficient linear low-dropout (LDO) voltage regulator from Microchip that offers up to 500 mA of continuous current with a dropout voltage of 280 mV. The MIC2214-FMBML-TR is aimed at applications requiring precision low-noise power supplies, such as very low current applications, powering sensitive analogue circuits, and powering digital systems where a reliable low-noise source is critical. This type of LDO can be used in a range of applications, including energy-harvesting applications, ultra-low power communication systems, LED driver circuits, medical instrumentation, and battery-powered devices.

The MIC2214-FMBML-TR is a monolithic LDO in a 3mm x 3mm tinyDFN package that provides 500 mA of continuous current. The device provides a pin-selectable feature that allows users to select between two available output voltages: either 1.0 V or 0.9 V (VOUT_LO). This device uses an external capacitor of minimum 100nF for reducing output voltage ripple. Furthermore, it features an internal pull-down resistor on the enable pin, allowing the user to connect it directly to logic circuitry. Additionally, the device has an adjustable Soft-Start, which enables a constant inrush current of less than 10µA.

The MIC2214-FMBML-TR also features over-current, short-circuit and thermal-overload protection. It provides a highly accurate target voltage output gain and low noise operation due to its excellent transient response. The device also is optimized for a wide input voltage range of 2.2 to 7 V, and has an enable voltage input range of 1.3V to 7.0V.

The MIC2214-FMBML-TR operates over the temperature range of -40°C to +125°C, allowing it to be used in extreme temperatures. The device utilizes an internal PMOS pass device, ensuring high PSRR and fast transient response even under very light load conditions. It has a maximum quiescent current of 2.2µA with output load, and can withstand over current up to 400 mA.

The MIC2214-FMBML-TR is a high-performance linear LDO voltage regulator suitable for applications with demanding voltage, noise and power consumption requirements, such as powering sensitive analogue circuits, powering digital systems automatically, controlling the output voltage of energy harvesting applications, and providing power to ultra-low power, communication systems, LED driver circuits and battery-operated devices.

In summary, the MIC2214-FMBML-TR is a highly efficient linear low-dropout (LDO) voltage regulator from Microchip. It can provide up to 500 mA of continuous current with an improved dropout voltage of 280 mV and pin-selectable feature for selecting two different output voltages. With an adjustable soft-start feature, it allows for a constant inrush current of less than 10µA and an improved PSRR for maximum performance. Additionally, it features an over-current, short-circuit and thermal-overload protection. The device offers a wide input voltage range from 2.2 to 7 V, low quiescent current, and wide operating temperature range from -40°C to +125°C. All these features make it suitable for a wide range of applications, such as ultra-low power communication systems, LED driver circuits, energy harvesting applications, medical instrumentation and battery-operated devices.
