Product details
Overview
MP2004DJ-PN-LF-P from Monolithic Power Systems is a dual-channel, low-noise, high-PSRR linear regulator in TSOT23-6 package, delivering 3.0V and 2.85V outputs with ±1% accuracy, 95μVRMS noise, and 69dB PSRR at 100Hz-designed for battery-powered handheld equipment requiring independent channel enable control and ultra-low quiescent current (114μA).
For engineers reviewing the MP2004DJ-PN-LF-P datasheet, MP2004DJ-PN-LF-P pinout, MP2004DJ-PN-LF-P application, or MP2004DJ-PN-LF-P equivalent, key selection criteria include per-channel enable logic, dropout voltage under load (110mV at 100mA), thermal shutdown threshold (140°C), and compatibility with low-ESR ceramic output capacitors (0.47–10μF).
Technical Context
The MP2004DJ-PN-LF-P integrates two independent PMOS-based LDOs with separate EN1/EN2 inputs enabling asynchronous channel control and near-zero shutdown current (≤1μA). Each regulator maintains regulation across 2.5V–6.0V input while delivering up to 200mA with 110mV dropout at 100mA load.
Its architecture achieves 95μVRMS integrated noise (10Hz–100kHz) and 69dB PSRR at 100Hz via internal compensation optimized for stability with 2.2μF ceramic output capacitors-eliminating need for external compensation components in standard configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.0V (Channel 1), 2.85V (Channel 2); fixed, factory-trimmed for ±1% accuracy across load/temperature |
| Max Output Current | 200mA per channel; supports independent loading without cross-regulation degradation |
| PSRR @ 100Hz | 69dB; suppresses ripple from noisy DC-DC stages feeding baseband or RF subsystems |
| Output Noise | 95μVRMS (10Hz–100kHz); enables clean power for ADC references and RF synthesizers |
| Dropout Voltage | 110mV at 100mA load; sustains regulation down to VIN = VOUT + 0.11V, critical for Li-ion battery discharge tail |
| Quiescent Current | 114μA (both channels active); minimizes standby drain in always-on system rails |
| Thermal Shutdown | 140°C activation with 10°C hysteresis; protects against sustained overload in compact enclosures |
Pinout & Package
MP2004DJ-PN-LF-P uses a 6-pin TSOT23-6 package with exposed pad for thermal dissipation (θJA = 220°C/W on 4-layer board). Pin 1 is bottom-left when reading top marking left-to-right.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT2 | Channel 2 regulated output | Delivers fixed 2.85V; requires local 0.47–10μF ceramic capacitor for stability |
| 2 - GND | Common ground reference | Must connect to large copper area or ground plane to manage thermal resistance and noise coupling |
| 3 - EN2 | Channel 2 enable input (active-high) | Logic-high ≥1.6V enables VOUT2; floating prohibited-tie to VIN or GND for default state |
| 4 - EN1 | Channel 1 enable input (active-high) | Independent control of 3.0V rail; allows staggered power-up or dynamic rail gating |
| 5 - VIN | Input supply pin | Accepts 2.5–6.0V; requires ≥0.47μF ceramic input capacitor adjacent to pin |
| 6 - VOUT1 | Channel 1 regulated output | Delivers fixed 3.0V; shares same noise/PSRR specs as VOUT2 but operates independently |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs in TSOT23-6 | Reduces board area by 40% vs. two discrete 3-pin regulators; eliminates inter-rail crosstalk in shared packages |
| Per-channel enable pins (EN1/EN2) | Enables power sequencing control-e.g., delay VOUT2 startup until VOUT1 stabilizes in multi-rail SoC systems |
| 95μVRMS output noise (10Hz–100kHz) | Meets noise floor requirements for 12-bit+ SAR ADCs and low-phase-noise VCOs without additional filtering |
| 69dB PSRR at 100Hz | Attenuates switching noise from upstream DC-DC converters powering baseband processors or audio codecs |
| 110mV dropout at 100mA | Extends usable battery life in single-cell Li-ion applications by maintaining regulation down to 3.11V input for 3.0V rail |
Applications
| Cellular Phone Baseband | Laptop USB-C Peripheral Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6216D302MR-G | Single-channel only; 3.0V fixed output; no second rail or EN2 pin | Requires two devices to match MP2004's dual-rail capability; lacks independent enable control | Select only if system needs only one regulated rail and space permits dual placement |
| Ricoh RP111Q282D-TR-F | 2.85V/3.0V dual output but uses NMOS pass device; higher dropout (250mV @ 100mA) | Reduced battery runtime in deep-discharge conditions due to higher minimum input requirement | Prefer when cost sensitivity outweighs efficiency and noise performance in non-critical rails |
Compared with XC6216D302MR-G and RP111Q282D-TR-F, MP2004DJ-PN-LF-P uniquely delivers matched dual outputs with per-channel enable, sub-100μVRMS noise, and PMOS-based ultra-low dropout-making it optimal for space-constrained, noise-sensitive, battery-dependent designs where rail independence is mandatory.

FAQ
What is the maximum allowable input voltage for MP2004DJ-PN-LF-P?
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 to the internal PMOS pass elements and protection circuitry. Operation above 6.0V voids parametric guarantees including PSRR, noise, and dropout performance.
Can MP2004DJ-PN-LF-P operate with ceramic output capacitors below 1μF?
Yes-MP2004DJ-PN-LF-P is stable with ceramic output capacitors as low as 0.47μF and ESR <1.2Ω. Using smaller values improves transient response speed but may increase output voltage ripple; 2.2μF is the typical value used in reference designs for optimal noise/PSRR balance.
Is there reverse current protection built into MP2004DJ-PN-LF-P?
No internal reverse current protection exists-the PMOS pass device has an inherent body diode from VIN to VOUT. If VOUT exceeds VIN by >0.3V, reverse conduction occurs. An external Schottky diode (anode to VOUT, cathode to VIN) is required to block reverse current in back-powering scenarios.
How does thermal shutdown behave during continuous overload?
When junction temperature reaches 140°C, both LDOs shut down simultaneously. After cooling by 10°C (to ~130°C), the device auto-restarts. This hiccup-mode cycling limits average power dissipation but requires careful PCB thermal design-especially with θJA = 220°C/W-to avoid sustained oscillation in high-ambient environments.
What is the minimum load current required for regulation stability?
No minimum load current is required-MP2004DJ-PN-LF-P maintains regulation from zero load to 200mA per channel. Quiescent current remains constant at 114μA (both channels enabled), and line/load regulation specs are guaranteed down to 1mA, making it suitable for intermittent-sensing applications.
Are the two output channels electrically isolated from each other?
The channels share only the common GND and VIN pins-there is no internal electrical connection between VOUT1 and VOUT2. However, substrate coupling and shared thermal mass cause minor cross-talk (<−40dB) at high frequencies; for critical isolation, separate ground pours and physical spacing are recommended.
Does MP2004DJ-PN-LF-P support adjustable output voltages?
No-MP2004DJ-PN-LF-P is a fixed-output device with factory-trimmed 3.0V and 2.85V rails. Adjustable versions (e.g., MP2004DJ-JG-LF-Z) use external resistor dividers but require different part numbers; this variant has no feedback pins or adjustment capability.
