Product details
Overview
MIC2211-JYYML-TR from Micrel is a dual-output µCap low dropout regulator IC with fixed 2.5V/1.9V outputs, delivering 150mA on VOUT1 and 300mA on VOUT2 in a 10-pin 3mm × 3mm MLF™ package. It features 1% initial output accuracy, 80mV dropout at 100mA, and ultra-low 48µA total quiescent current - optimized for battery-powered cellular phones and wireless modems.
For engineers reviewing the MIC2211-JYYML-TR datasheet, MIC2211-JYYML-TR pinout, MIC2211-JYYML-TR application, or MIC2211-JYYML-TR equivalent, key selection criteria include dual independent enable control (EN1/EN2), ceramic-capacitor stability (1µF per output), thermal shutdown protection, and operation across –40°C to +125°C junction temperature.
Technical Context
The MIC2211-JYYML-TR integrates two independent LDO regulators sharing a common VIN input but featuring separate EN1/EN2 logic-controlled enables and dedicated output pins (VOUT1/VOUT2). Each LDO uses a µCap architecture requiring only 1µF ceramic output capacitors for stability, eliminating bulky tantalum or electrolytic components.
It employs an internal bandgap reference bypassed via CBYP (0.01µF recommended) to achieve 30µVrms output noise and 60dB PSRR at 1kHz. Ground current remains constant at 48µA with zero load and rises only marginally under full load - critical for standby power integrity in portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | Fixed 2.5V (VOUT1) and 1.9V (VOUT2) - powers baseband processor core and I/O rails simultaneously |
| Max Output Current | 150mA on VOUT1, 300mA on VOUT2 - supports mixed-signal SoC voltage domains |
| Dropout Voltage | 80mV @ 100mA - enables regulation down to VIN = 2.58V for VOUT1 and VIN = 1.98V for VOUT2 |
| Quiescent Current | 48µA total (24µA per LDO) - minimizes battery drain during system sleep modes |
| Accuracy | +1.0% initial, +2.0% over –40°C to +125°C - ensures reliable voltage margins for logic-level compliance |
| PSRR | 60dB @ 1kHz, 40dB @ 20kHz - suppresses switching noise from adjacent DC/DC converters |
| Noise | 30µVrms (10Hz–100kHz) - preserves signal integrity in RF and audio subsystems |
Pinout & Package
Package: 10-pin 3mm × 3mm MLF™ (exposed pad), RoHS-compliant, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Common input supply | Shared 2.25V–5.5V input for both LDOs; requires local 1µF ceramic bypass |
| EN1 (Pin 2) | LDO1 enable input | Active-high CMOS control (1.8V min high); enables/disables 2.5V/150mA output independently |
| EN2 (Pin 3) | LDO2 enable input | Active-high CMOS control (1.8V min high); enables/disables 1.9V/300mA output independently |
| CBYP (Pin 4) | Reference bypass | Connects 0.01µF ceramic to GND to reduce output noise and improve PSRR |
| NC (Pins 5,7,8) | No connection | Unbonded; must remain unconnected and unstubbed on PCB |
| GND (Pin 6 & EP) | Power ground | Primary ground return; exposed pad must be soldered to solid GND plane for thermal and electrical performance |
| VOUT2 (Pin 9) | LDO2 output | Delivers regulated 1.9V up to 300mA; requires 1µF X7R/X5R ceramic capacitor |
| VOUT1 (Pin 10) | LDO1 output | Delivers regulated 2.5V up to 150mA; requires 1µF X7R/X5R ceramic capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enables | EN1 and EN2 allow staggered power-up, dynamic rail gating, and independent sleep/wake control |
| µCap ceramic stability | Stable with 1µF X7R/X5R output capacitors - eliminates ESR requirements and reduces board area by >50% vs. tantalum |
| Zero-off-mode current | Draws ≤2.0µA total when both EN1 and EN2 are low - enables true system-level power cutoff |
| Thermal & current protection | Internal thermal shutdown and foldback current limiting prevent damage during overload or ambient overheating |
| Low-noise reference bypass | CBYP pin accepts 0.01µF capacitor to reduce output spectral noise density below 10nV/√Hz at 10kHz |

FAQ
What are the exact output voltages of the MIC2211-JYYML-TR?
The MIC2211-JYYML-TR provides fixed 2.5V on VOUT1 and 1.9V on VOUT2, as confirmed by Micrel's ordering information table where "JYY" decodes to 2.5V/1.9V. These values are factory-trimmed and specified with ±1.0% initial accuracy and ±2.0% variation over –40°C to +125°C junction temperature. No external resistors are required to set these outputs.
Does the MIC2211-JYYML-TR require external capacitors, and what types are recommended?
Yes - the MIC2211-JYYML-TR requires three external capacitors: a 1µF ceramic input capacitor (X7R/X5R) near VIN, a 1µF ceramic output capacitor (X7R/X5R) on each VOUT pin, and a 0.01µF ceramic capacitor from CBYP to GND. Y5V/Z5U dielectrics are discouraged due to excessive capacitance drift; X7R is explicitly recommended for stable performance across temperature.
How does the enable functionality work on the MIC2211-JYYML-TR?
The MIC2211-JYYML-TR features two independent CMOS-compatible enable inputs: EN1 controls VOUT1 (2.5V), and EN2 controls VOUT2 (1.9V). Both are active-high with VIH ≥ 1.8V for guaranteed turn-on and VIL ≤ 0.6V for guaranteed shutdown. Each draws <1µA when asserted, and floating is prohibited - pull-down resistors are recommended if control signals are open-drain.
What thermal protection mechanisms does the MIC2211-JYYML-TR include?
The MIC2211-JYYML-TR integrates thermal shutdown that activates when junction temperature exceeds +150°C (typical), forcing both outputs into high-impedance state until die temperature falls below the hysteresis threshold (~135°C). It also includes current-limit protection on both outputs - foldback limiting triggers at ~460mA on VOUT1 and ~700mA on VOUT2 - preventing destructive overloads during short-circuit events.
Can the MIC2211-JYYML-TR operate from a single-cell Li-ion battery?
Yes - the MIC2211-JYYML-TR supports input voltages from 2.25V to 5.5V, fully covering the discharge range of a single-cell Li-ion (3.0V–4.2V nominal, down to ~2.7V cutoff). With 80mV dropout at 100mA, it maintains regulation on VOUT1 (2.5V) down to VIN = 2.58V and on VOUT2 (1.9V) down to VIN = 1.98V, ensuring functional operation even at end-of-discharge.
