MIC2212-GKYML

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MIC2212-GKYML is a dual µCap low dropout regulator and power-on reset controller manufactured by Micrel (Microchip). It features two fixed positive LDO outputs: Output 1 provides 2.8V at up to 150mA, and Output 2 provides 2.6V at up to 300mA. The device utilizes a 10-pin MLF package measuring 3mm x 3mm. It incorporates a power-on reset circuit with a fixed delay time of 140ms and an active-low reset output. The regulator supports an input voltage range from 2.25V to 5.5V, offering high PSRR and low ground current for battery-operated applications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix GKYML against official Microchip documentation to confirm the exact output voltage configuration and package variant. Ensure compatibility with the required input voltage range and load currents. Check for RoHS compliance status and moisture sensitivity level requirements for surface mount assembly processes.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a dual supply rail solution is needed with integrated reset functionality. The 2.8V/2.6V combination suits systems where one rail powers logic and another powers analog peripherals. Consider the 150mA and 300mA current limits to ensure adequate headroom for peak loads without exceeding thermal constraints in the MLF-10 package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

The MIC2212 belongs to the Micrel µCap LDO family, designed for space-constrained applications. It replaces discrete regulator and reset circuits, reducing board area. The series includes variants with different output voltages and reset delays, sharing the same compact footprint and low-power architecture optimized for portable electronics.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes include other MIC2212 variants with matching output voltages, such as MIC2212-GLYML or MIC2212-2.8BML, provided the reset delay and pinout are identical. Cross-reference with MIC5211 or MIC5249 families only if functional differences like current capacity or reset behavior are acceptable.
