Product details
Overview
MIC2211-JPYML-TR from Micrel is a dual-output µCap low dropout regulator IC with fixed 2.5V/3.0V outputs, delivering 150mA and 300mA respectively. It operates from 2.25V to 5.5V input, achieves 1% initial output accuracy, 80mV dropout at 100mA, and ultra-low 48µA total quiescent current. Designed for space-constrained portable electronics, it powers baseband processors and VCORE/VI/O rails in cellular handsets.
For engineers reviewing the MIC2211-JPYML-TR datasheet, MIC2211-JPYML-TR pinout, MIC2211-JPYML-TR application, or MIC2211-JPYML-TR equivalent, key selection criteria include dual independent enable control, ceramic-capacitor stability, thermal shutdown protection, and MLF™-10 package compatibility with high-density PCB layouts.
Technical Context
The MIC2211-JPYML-TR integrates two independent LDO regulators sharing a common VIN and GND but featuring separate EN1/EN2 inputs and VOUT1/VOUT2 outputs. Each regulator uses a µCap architecture requiring only 1µF ceramic output capacitors and a 0.01µF bypass capacitor on CBYP to achieve stable regulation and 60dB PSRR at 1kHz.
It implements internal current limiting (150mA/300mA), thermal shutdown, and logic-compatible enable thresholds (1.8V high, 0.6V low). Ground current remains at 48µA with zero load and rises to 60µA under full 150mA+300mA output conditions, supporting battery longevity in always-on subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | Fixed 2.5V (VOUT1) and 3.0V (VOUT2); enables simultaneous core/I/O rail generation without external feedback. |
| Output Current | VOUT1 supports 150mA; VOUT2 supports 300mA - sufficient for baseband processor I/O and analog subsystems. |
| Dropout Voltage | 80mV @ 100mA load - allows operation down to 2.58V input for 2.5V output, extending battery runtime. |
| Quiescent Current | 48µA total (24µA per LDO) - minimizes standby power loss in sleep-mode mobile devices. |
| Accuracy | +1.0% initial, +2.0% over –40°C to +125°C - ensures reliable voltage margins for sensitive RF and digital circuits. |
| PSRR | 60dB @ 1kHz, 40dB @ 20kHz - suppresses switching noise from adjacent DC/DC converters. |
| Package | 10-pin 3mm × 3mm MLF™ with exposed pad - provides low thermal resistance (θJA = 60°C/W) and compact footprint. |
Pinout & Package
Package: 10-pin 3mm × 3mm MLF™ (MicroLeadFrame) with exposed thermal pad connected to GND. RoHS-compliant, Pb-free, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Common input supply | Shared input for both LDOs; must be bypassed with ≥1µF ceramic capacitor near pin. |
| EN1 (Pin 2) | Regulator 1 enable | Active-high TTL/CMOS input; drives VOUT1 on/off independently; requires ≥1.8V to enable. |
| EN2 (Pin 3) | Regulator 2 enable | Active-high TTL/CMOS input; drives VOUT2 on/off independently; no cross-talk with EN1. |
| CBYP (Pin 4) | Reference bypass | Connects 0.01µF ceramic to GND to reduce output noise and improve PSRR; optional but recommended. |
| NC (Pins 5,7,8) | No connection | Unbonded pins; must remain unconnected and unpopulated on PCB. |
| GND (Pin 6 & EP) | Power ground | Primary ground return; exposed pad (EP) is internally tied to Pin 6 and must be soldered to PCB ground plane. |
| VOUT2 (Pin 9) | 300mA output | Delivers regulated 3.0V; requires 1µF X7R/X5R ceramic capacitor directly at pin for stability. |
| VOUT1 (Pin 10) | 150mA output | Delivers regulated 2.5V; decoupled separately from VOUT2 to prevent coupling during transient loads. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable control | EN1 and EN2 allow staggered power-up/down sequencing between core (2.5V) and I/O (3.0V) rails - critical for ASIC reset timing compliance. |
| µCap ceramic-stable design | Stabilized with 1µF ceramic output caps per channel - eliminates large tantalum/Al-elec requirements, reducing board area by >50% vs legacy LDOs. |
| Ultra-low ground current | 48µA total quiescent current - extends shelf life and standby time in battery-backed applications like feature phones and modems. |
| Thermal & current protection | Integrated thermal shutdown and foldback current limiting - prevents damage during short-circuit or overload without external circuitry. |
| High PSRR with bypass option | 60dB rejection at 1kHz improves RF section immunity when CBYP = 0.01µF is used - essential for GSM/EDGE transceiver coexistence. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS70245PWPR | 2.5V/3.0V fixed outputs; 250mA/250mA; higher 125µA IQ; 16-pin HTSSOP package | Larger footprint; lacks CBYP pin for noise optimization; lower PSRR (55dB @ 1kHz) | Choose when board space permits larger package and higher IQ is acceptable for non-battery-critical systems. |
| RT9013-25PF/30PF | Separate 2.5V and 3.0V single-LDOs; 300mA each; 65µA IQ per device; SOT-23-5 packages | Requires two ICs and extra passives; no shared enable logic; higher total ground current (130µA) | Choose when design requires physical separation of rails or existing layout uses SOT-23 footprints. |
Compared with TPS70245PWPR and RT9013-25PF/30PF, the MIC2211-JPYML-TR delivers superior battery efficiency via 48µA total IQ, smaller 3×3mm MLF™ footprint, and dedicated CBYP pin for optimized noise performance - making it the preferred choice for space- and runtime-constrained portable designs.

FAQ
What are the exact output voltages of the MIC2211-JPYML-TR?
The MIC2211-JPYML-TR provides fixed output voltages of 2.5V on VOUT1 (Pin 10) and 3.0V on VOUT2 (Pin 9), as confirmed by Micrel's ordering information table where "JPYML" maps to "2.5V/3.0V". These values are factory-trimmed and do not require external resistors, ensuring ±1.0% initial accuracy across production lots.
Does the MIC2211-JPYML-TR require external capacitors, and what types are specified?
Yes, the MIC2211-JPYML-TR requires three external capacitors: a ≥1µF ceramic input capacitor at VIN, a 1µF X7R/X5R ceramic capacitor at each output (VOUT1 and VOUT2), and a 0.01µF ceramic capacitor from CBYP (Pin 4) to GND. These values are mandatory for stability, noise reduction, and PSRR performance per the datasheet's Electrical Characteristics and Functional Description sections.
How does the enable functionality work on the MIC2211-JPYML-TR?
The MIC2211-JPYML-TR features two independent active-high enable inputs: EN1 (Pin 2) controls VOUT1, and EN2 (Pin 3) controls VOUT2. Both require ≥1.8V to activate and ≤0.6V to disable. Neither pin may float - they must be pulled high via MCU GPIO or pulled low via logic circuitry. This allows precise sequencing, such as powering VOUT2 (3.0V I/O) before VOUT1 (2.5V core).
What thermal protection mechanisms does the MIC2211-JPYML-TR include?
The MIC2211-JPYML-TR incorporates internal thermal shutdown that activates when junction temperature exceeds +125°C, forcing both outputs into high-impedance state until die temperature falls below the hysteresis threshold. It also includes current-limit protection: 150mA foldback for VOUT1 and 300mA for VOUT2. These functions are fully integrated and require no external components.
Is the MIC2211-JPYML-TR compatible with lead-free reflow processes?
Yes, the MIC2211-JPYML-TR is Pb-free and rated for standard lead-free reflow profiles, including peak temperatures up to 260°C for 5 seconds as specified in the Absolute Maximum Ratings table. Its MLF™-10 package uses NiPdAu terminal finish and complies with JEDEC J-STD-020 moisture sensitivity level 3, requiring bake prior to reflow if exposed beyond floor life.
