Product details
Overview
MIC2211-PPYML-TR from Micrel is a dual-output µCap low dropout regulator IC delivering 3.0V/3.0V at 150mA and 300mA respectively, with 1% initial output accuracy, 80mV dropout at 100mA, and ultra-low 48µA total quiescent current. It operates from 2.25V–5.5V input and targets space-constrained, battery-powered systems requiring independent voltage rail control.
For engineers reviewing the MIC2211-PPYML-TR datasheet, MIC2211-PPYML-TR pinout, MIC2211-PPYML-TR application, or MIC2211-PPYML-TR equivalent, key selection criteria include dual-rail enable independence, ceramic-capacitor stability (1µF per output), thermal shutdown protection, and 10-pin 3mm × 3mm MLF™ package compatibility with high-density portable PCB layouts.
Technical Context
The MIC2211-PPYML-TR integrates two independent LDO regulators sharing a common VIN and GND but featuring separate EN1/EN2 control inputs and dedicated VOUT1/VOUT2 outputs. Each regulator uses a µCap architecture optimized for stability with small ceramic capacitors-no external compensation required.
It implements CMOS-compatible enable logic (1.8V threshold), internal reference bypass via CBYP pin (0.01µF recommended), and thermal shutdown with current limiting (460mA max on LDO1, 700mA on LDO2). Ground current remains fixed at 48µA in active no-load state and rises only marginally under full load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | Fixed 3.0V / 3.0V - enables dual-core or I/O + core rail generation from single input |
| Max Output Currents | 150mA (VOUT1), 300mA (VOUT2) - supports mixed-signal baseband processors and RF sections |
| Dropout Voltage | 80mV @ 100mA - sustains regulation down to VIN = 3.08V, critical for Li-ion battery discharge tail |
| Quiescent Current | 48µA total - minimizes standby power loss in always-on subsystems |
| Accuracy | ±1.0% initial, ±2.0% over –40°C to +125°C - ensures timing-critical logic supply stability |
| PSRR | 60dB @ 1kHz - suppresses switching noise from adjacent DC/DC converters |
| Package | 10-pin 3mm × 3mm MLF™ - exposes thermal pad for efficient heat dissipation in thin-profile handsets |
Pinout & Package
10-pin 3mm × 3mm MLF™ (MicroLeadFrame) package with exposed thermal pad connected internally to GND (Pin 6 and EP). Pin 1 is VIN; Pins 2 and 3 are independent enable inputs; Pin 4 is CBYP for reference bypass; Pins 5, 7, 8 are NC; Pin 6 is GND; Pin 9 is VOUT2 (300mA); Pin 10 is VOUT1 (150mA).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Common input supply | Shared 2.25–5.5V input for both regulators; requires local 1µF ceramic bypass |
| EN1 (Pin 2) | LDO1 enable control | Active-high CMOS input (1.8V min); allows independent sequencing of first output rail |
| EN2 (Pin 3) | LDO2 enable control | Active-high CMOS input (1.8V min); enables staggered power-up of second rail |
| CBYP (Pin 4) | Reference bypass node | Connects to 0.01µF capacitor to reduce output noise and improve PSRR by >20dB |
| GND (Pin 6 & EP) | Power ground reference | Must be soldered to large PCB copper pour; primary thermal path for 60°C/W θJA |
| VOUT2 (Pin 9) | High-current output | 300mA capable rail; requires 1µF X7R ceramic capacitor placed within 2mm of pin |
| VOUT1 (Pin 10) | Medium-current output | 150mA capable rail; same capacitor requirements as VOUT2; decoupled independently |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 allow precise power sequencing-e.g., boot core before I/O, or disable unused rail during sleep |
| µCap ceramic-stable architecture | Stable with 1µF X7R ceramic output caps per rail-eliminates bulky tantalum or electrolytic capacitors |
| Ultra-low quiescent current | 48µA total (24µA per LDO) enables >1-year battery life in low-duty-cycle sensor nodes |
| Thermal shutdown + current limit | Protects against short-circuit faults without external circuitry; auto-recovery after cooldown |
| Fixed 3.0V/3.0V output pair | Optimized for dual-voltage microcontrollers or FPGA I/O banks requiring matched supply rails |
Applications
| Cellular Baseband Power | Wireless Modem Core Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS70245PWP | 250mA/250mA dual outputs; 16-pin HTSSOP; higher 85µA IQ; requires larger 2.2µF output caps | Less suitable for ultra-thin handsets due to 1mm height and larger footprint | Preferred when higher current symmetry and thermal margin are needed over size constraints |
| RT9013-30GJ5 | Single 300mA LDO; 5-pin SOT-25; no dual-rail or independent enable capability | Cannot replace MIC2211-PPYML-TR in dual-rail designs without adding second regulator | Only viable if system redesign accommodates two separate single-channel LDOs |
Compared with TPS70245PWP and RT9013-30GJ5, the MIC2211-PPYML-TR uniquely delivers matched 3.0V/3.0V outputs in a 3mm × 3mm footprint with sub-50µA quiescent current and true per-rail enable control-making it irreplaceable in space- and power-constrained dual-rail applications.

FAQ
What is the maximum input voltage rating for the MIC2211-PPYML-TR?
The MIC2211-PPYML-TR has an absolute maximum input voltage rating of 7V, but its specified operating range is 2.25V to 5.5V. Exceeding 5.5V may cause permanent damage or unpredictable behavior, and operation above this range voids parametric guarantees including dropout voltage and accuracy. The MIC2211-PPYML-TR must be used within its 2.25–5.5V operational window to ensure compliance with all published electrical characteristics.
Does the MIC2211-PPYML-TR require external capacitors, and what types are recommended?
Yes, the MIC2211-PPYML-TR requires three external capacitors: a 1µF ceramic input capacitor (X7R/X5R), a 1µF ceramic output capacitor per rail (X7R/X5R), and a 0.01µF ceramic capacitor on the CBYP pin. Z5U or Y5V dielectrics are not recommended due to excessive capacitance drift over temperature. All capacitors must be placed within 2mm of their respective pins to maintain stability and noise performance as validated in the MIC2211-PPYML-TR datasheet.
Can the MIC2211-PPYML-TR be used with adjustable output voltages?
No-the MIC2211-PPYML-TR is a fixed-output variant configured for 3.0V/3.0V. Adjustable versions (e.g., MIC2211-ADJ/ADJBML) exist in the same family but use different pinouts (ADJ1/ADJ2 pins) and resistor networks. The MIC2211-PPYML-TR lacks ADJ pins and cannot be reconfigured; its output voltages are laser-trimmed during manufacturing and are not user-modifiable.
What is the thermal performance of the MIC2211-PPYML-TR in its MLF™ package?
The MIC2211-PPYML-TR in the 10-pin 3mm × 3mm MLF™ package has a junction-to-ambient thermal resistance (θJA) of 60°C/W when mounted on a standard 4-layer PCB with 1in² 2oz copper pour connected to the exposed pad. Under worst-case conditions (300mA on VOUT2 + 150mA on VOUT1 at 5.5V input), power dissipation reaches ~1.1W, resulting in ~66°C junction rise above ambient-well within the –40°C to +125°C operating range if ambient stays below +59°C.
How does the MIC2211-PPYML-TR behave when one enable pin is asserted and the other is not?
When EN1 is high and EN2 is low, only VOUT1 (150mA rail) is active; VOUT2 is fully disabled with zero output current and <2µA ground current. Conversely, when EN2 is high and EN1 is low, only VOUT2 (300mA rail) operates. Both outputs can be disabled simultaneously (EN1 = EN2 = low), reducing total ground current to ≤2µA. This behavior is explicitly characterized in the MIC2211-PPYML-TR datasheet's "Ground Pin Current in Shutdown" specification.
