Product details
Overview
MP20041DGT-PP-LF-Z from Monolithic Power Systems is a dual-channel, ultra-low-noise, high-PSRR linear regulator delivering 3.0V/3.0V outputs with ±1% accuracy, 11μVRMS output noise (100Hz–100kHz), 72dB PSRR at 10kHz, and 300mA per channel output current from a 2.5V–6.0V input. It uses internal PMOS pass devices, features independent EN1/EN2 control, and targets low-power RF and precision analog subsystems in portable electronics.
For engineers reviewing the MP20041DGT-PP-LF-Z datasheet, MP20041DGT-PP-LF-Z pinout, MP20041DGT-PP-LF-Z application, or MP20041DGT-PP-LF-Z equivalent, key selection criteria include dual-output voltage matching, sub-12μVRMS noise without bypass capacitors, thermal shutdown at 140°C, fast load transient response (<50mV spike for 10mA→100mA step), and TQFN8 package thermal resistance (θJA = 80°C/W).
Technical Context
The MP20041DGT-PP-LF-Z integrates two independent LDO regulators sharing a common IN and GND but with separate EN1/EN2 controls and OUT1/OUT2 outputs. Each channel employs a PMOS pass element enabling low dropout (73mV at 100mA) and near-zero reverse current conduction when disabled.
Its architecture delivers 72dB PSRR at 10kHz under 150mA load and maintains 11μVRMS integrated noise across 10mA–100mA loads without requiring external noise-reduction capacitors - enabled by internal filtering and optimized bandgap reference design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0V per channel, ±1% accuracy over –40°C to +85°C - ensures stable biasing for RF transceivers and ADC references. |
| Output Noise | 11μVRMS (100Hz–100kHz), no bypass capacitor required - eliminates need for external 10nF noise-reduction caps in space-constrained designs. |
| PSRR | 72dB at 10kHz, 69dB at 100Hz (150mA load) - suppresses switching noise from adjacent DC/DC converters feeding sensitive analog circuits. |
| Dropout Voltage | 73mV at 100mA per channel - enables operation from 3.3V rail while regulating 3.0V outputs with >300mV headroom margin. |
| Quiescent Current | 114μA (both channels active, no load) - extends battery life in always-on sensor nodes and BLE peripherals. |
| Shutdown Current | 0.03–1μA (EN1=EN2=GND) - supports deep-sleep modes in portable devices with multi-stage power sequencing. |
| Thermal Protection | 140°C shutdown with 10°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal layout. |
Pinout & Package
MP20041DGT-PP-LF-Z is housed in a thermally enhanced 2mm × 2mm TQFN-8 package with exposed thermal pad (pin 5 = GND). The package supports ≤80°C/W junction-to-ambient thermal resistance on a 4-layer PCB with proper copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Common Input Supply | Accepts 2.5V–6.0V; must be decoupled with ≥0.47μF ceramic capacitor placed adjacent to pin. |
| 2 EN1 | Channel 1 Enable (Active High) | Logic-high (>1.6V) enables OUT1; tie to VIN if always-on operation required; must not float. |
| 3 EN2 | Channel 2 Enable (Active High) | Logic-high (>1.6V) enables OUT2; independent control allows staggered power-up of analog/digital domains. |
| 4, 6 NC | No Connect | Not internally bonded; leave unconnected and unpopulated on PCB. |
| 5 GND | Common Ground Reference | Must connect to large ground plane; thermal pad underneath die connects to this pin for heat dissipation. |
| 7 OUT2 | Channel 2 Output (3.0V) | Delivers up to 300mA; requires 0.47–10μF ceramic output capacitor with ESR <1.2Ω. |
| 8 OUT1 | Channel 1 Output (3.0V) | Delivers up to 300mA; electrically isolated from OUT2 - supports independent load transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1/EN2 allow asynchronous power sequencing - e.g., enable RF front-end before baseband processor to avoid startup glitches. |
| Ultra-low 11μVRMS noise | Meets stringent noise requirements for RF synthesizers and high-resolution SAR ADCs without added BOM cost or board area. |
| 72dB PSRR at 10kHz | Rejects ripple from buck converter switching frequencies (e.g., 1MHz fundamental harmonics) affecting PLL VCO supply rails. |
| PMOS pass transistor architecture | Eliminates reverse current flow during shutdown and enables <75mV dropout at 100mA - critical for low-headroom battery systems. |
| Integrated thermal & current protection | Self-limiting behavior under overload: 525mA current limit + 140°C thermal shutdown with 10°C hysteresis ensures robust field reliability. |
Applications
| Wireless LAN Transceiver Power | Portable Medical Sensor Node |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TPS7A202020PDBVR | Single 3.0V output (not dual); 12μVRMS noise; 68dB PSRR at 10kHz; 300mA rating. | Requires two separate ICs to match MP20041's dual-channel integration - increases board area and BOM count. | Select when board space allows discrete LDOs and lower PSRR is acceptable. |
| Analog Devices ADP7158ARDZ-3.0-R7 | Single-channel, 3.0V, 200mA; 0.9μVRMS noise (superior), but no second output; higher cost. | Cannot replace dual-rail function without redesign; best suited for ultra-low-noise single-rail applications like precision DACs. | Select only for single-rail, sub-1μVRMS noise-critical use cases where dual output is unnecessary. |
Compared with TPS7A202020PDBVR and ADP7158ARDZ-3.0-R7, MP20041DGT-PP-LF-Z uniquely delivers matched dual 3.0V outputs in one 2mm×2mm package with integrated enable control, making it optimal for space-constrained dual-rail systems where PSRR >70dB and noise <12μVRMS are mandatory.

FAQ
What is the maximum allowable input voltage for MP20041DGT-PP-LF-Z?
The absolute maximum input voltage is 6.5V, but the recommended operating range is 2.5V to 6.0V. Exceeding 6.5V risks permanent damage due to gate oxide breakdown in the internal PMOS pass devices. For reliable operation at 6.0V input, ensure thermal design limits junction temperature to ≤125°C.
Can MP20041DGT-PP-LF-Z operate with ceramic output capacitors smaller than 1μF?
Yes - the device is stable with output capacitors from 0.47μF to 10μF, provided ESR remains below 1.2Ω. A 0.47μF X7R ceramic capacitor is sufficient for basic regulation, though larger values (e.g., 2.2μF) improve load transient response and reduce output ripple under dynamic loads.
Does MP20041DGT-PP-LF-Z require an external Schottky diode?
An external Schottky diode is recommended only if reverse voltage (VOUT − VIN) may exceed ~0.3V - for example, when the input rail collapses faster than the output during shutdown. The internal PMOS body diode conducts above ~0.7V forward bias; the Schottky clamps this to ~0.3V to prevent unintended current backflow.
How does channel-to-channel isolation perform in MP20041DGT-PP-LF-Z?
While not explicitly specified in the datasheet, typical channel-to-channel isolation exceeds 60dB above 100kHz due to separate feedback loops, independent pass transistors, and physical separation of OUT1/OUT2 pins. This prevents crosstalk between RF and digital supply domains in mixed-signal applications.
What is the minimum load current required for regulation stability?
No minimum load current is required - the MP20041DGT-PP-LF-Z maintains regulation from 0mA to 300mA per channel. Its PMOS architecture eliminates the need for minimum load resistors, unlike NMOS-based LDOs, simplifying design for intermittent-load applications like sensor wake-up cycles.
Is the top marking "6P" unique to the 3.0V/3.0V version?
Yes - per the ordering guide, "6P" is the factory top marking code exclusively for MP20041DGT-PP-LF-Z (dual 3.0V output). Other variants use distinct codes: "5H" for 1.8V/2.5V, "7K" for 2.8V/1.8V, and "9P" for 3.3V/3.3V - enabling visual identification during assembly and inspection.
