This dual-rail configuration suits designs that need separate analog and digital supply voltages from a single input up to 5.5 V. Each regulator includes its own enable control and independent protection against over-current and over-temperature events, allowing the system to sequence the rails or shut down one domain without affecting the other. ## PSRR and noise rejection across frequency Power supply rejection ratio is specified at 60 dB at 1 kHz, rolling off to 40 dB at 20 kHz. This profile is adequate for cleaning up switching-regulator ripple in the audio band, but the droop above 10 kHz means the LDO alone may not suppress high-frequency noise from a DC-DC converter switching at several hundred kilohertz — additional post-filter capacitance or a ferrite bead may be needed on sensitive analog rails. ## Dropout voltage and quiescent current Maximum dropout is 0.25 V at the 150 mA output and 0.42 V at the 300 mA output, so the input rail needs at least 3.25 V to maintain regulation on the 3.0 V channel under full load. Quiescent current is 80 µA typical — low enough for battery-operated equipment but not the ultra-low-Iq tier found in always-on wearables. No official second-source cross-reference is listed, so dual-sourcing this BOM line would require qualifying a functionally equivalent dual LDO from another vendor with matching output voltages and package footprint.","metaTitle":"MIC2211-PMBML Dual LDO, 150mA/300mA, 3V/2.8V Fixed Output","metaDescription":"Micrel MIC2211-PMBML dual LDO regulator, 150 mA and 300 mA outputs, fixed 3.0 V and 2.8 V. 60 dB PSRR at 1 kHz, -40°C to 125°C, 10-MLF package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"PSRR":"60dB ~ 40dB (1KHz ~ 20kHz)","Package":"Bulk","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad, 10-MLF®","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"150mA, 300mA","Protection Features":"Over Current, Over Temperature","Number of Regulators":"2","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C","Voltage - Input (Max)":"5.5V","Voltage Dropout (Max)":"0.25V @ 150mA, 0.42V @ 300mA","Supplier Device Package":"10-MLF® (3x3)","Current - Quiescent (Iq)":"80 µA","Voltage - Output (Min/Fixed)":"3V, 2.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.42","priceTiers":[{"qty":722,"price":"$0.42000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/879e70856c3c6fa8bee21a3d3fe3b494.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MIC2211-PMBML/alternatives.json"},"ai":{"faq":[{"question":"Is MIC2211-PMBML active or obsolete?","answer":"It remains available for new designs and production builds."},{"question":"What are the output current ratings of MIC2211-PMBML?","answer":"The first regulator output is rated for 150 mA at a fixed 3.0 V, and the second regulator output is rated for 300 mA at a fixed 2.8 V."},{"question":"Is MIC2211-PMBML a dual output LDO?","answer":"Yes, the MIC2211-PMBML integrates two independent LDO regulators in a single package, each with its own enable control and protection circuitry."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/MIC2211-PMBML","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/MIC2211-PMBML when reusing this data.
