Product details
Overview
MP2004DJ-MG-LF-P from Monolithic Power Systems is a dual-channel, low-noise, high-PSRR linear regulator with fixed 2.8V and 1.8V outputs, ±1% accuracy, 200mA per channel output capability, and 95μVRMS output noise - designed for power-sensitive portable electronics requiring independent enable control and ultra-low quiescent current (114μA).
For engineers reviewing the MP2004DJ-MG-LF-P datasheet, MP2004DJ-MG-LF-P pinout, MP2004DJ-MG-LF-P application, or MP2004DJ-MG-LF-P equivalent, key selection criteria include dual-output voltage matching, TSOT23-6 footprint compatibility, fast transient response with small ceramic capacitors, and battery-aware shutdown behavior with <1μA total supply current in deep-off mode.
Technical Context
The MP2004DJ-MG-LF-P integrates two independent PMOS-based LDOs with separate EN1/EN2 inputs, enabling asynchronous channel control and zero-cross coupling. Each regulator maintains regulation down to 110mV dropout at 100mA and delivers 69dB PSRR at 100Hz with 2.2μF ceramic output capacitance.
It features internal thermal shutdown (140°C trip, 10°C hysteresis) and per-channel current limiting (450mA typical), with guaranteed operation across –40°C to +85°C ambient. The device requires no external compensation and supports stable operation with 0.47–10μF ceramic output capacitors having ESR <1.2Ω.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 2.8V (Channel 1) and 1.8V (Channel 2), fixed and factory-trimmed |
| Output Accuracy | ±1% over load (1–200mA), line (2.5–6.0V), and temperature (–40°C to +85°C) |
| Max Output Current | 200mA per channel continuous; 450mA current limit per channel |
| PSRR @ 100Hz | 69dB - suppresses low-frequency supply ripple critical for RF/analog subsystems |
| Output Noise | 95μVRMS (10Hz–100kHz) - enables clean power for precision ADCs and PLLs |
| Quiescent Current | 114μA (both channels active, no load); <1μA in full shutdown (EN1=EN2=GND) |
| Dropout Voltage | 110mV @ 100mA (VOUT1=2.8V); 250mV @ 200mA - sustains regulation under tight input margins |
Pinout & Package
MP2004DJ-MG-LF-P is housed in a 6-pin TSOT23-6 package (0.95mm pitch, 2.9mm × 1.6mm footprint) with exposed pad not electrically connected. Thermal resistance θJA = 220°C/W on standard 4-layer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT2 | Channel 2 regulated output | Delivers fixed 1.8V; requires local 0.47–10μF ceramic capacitor to GND |
| 2 - GND | Analog/digital common reference | Must connect to low-impedance ground plane; critical for noise and thermal performance |
| 3 - EN2 | Channel 2 enable input (active-high) | Logic-high ≥1.6V enables VOUT2; must not float - tie to VIN or GND if unused |
| 4 - EN1 | Channel 1 enable input (active-high) | Independent control of 2.8V rail; enables power sequencing and dynamic power gating |
| 5 - VIN | Input supply (2.5–6.0V) | Shared input for both LDOs; requires ≥0.47μF ceramic bypass capacitor |
| 6 - VOUT1 | Channel 1 regulated output | Delivers fixed 2.8V; decoupling capacitor placement directly impacts load-transient spike |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable pins | EN1/EN2 allow staggered power-up, selective rail shutdown, and system-level power sequencing without external logic |
| Ultra-low output noise | 95μVRMS enables direct powering of noise-sensitive analog blocks (e.g., VCOs, SAR ADC references) |
| High PSRR at low frequency | 69dB @ 100Hz rejects switching noise from upstream DC/DC converters feeding VIN |
| PMOS pass element architecture | Enables low dropout (110mV @ 100mA) and eliminates reverse-current path without external diode in most cases |
| Thermal & current protection | Auto-recovering 140°C thermal shutdown with 10°C hysteresis and per-channel 450mA current limit ensure robustness under fault conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6223D2818MR-G | Fixed 2.8V/1.8V outputs, but only 150mA per channel and 120μVRMS noise | Lacks independent EN pins - uses single enable for both channels | Choose when lower cost is prioritized over noise performance and sequencing flexibility |
| Ricoh RP512K2818-TR-F | 200mA per channel, 75dB PSRR @ 100Hz, but 150μVRMS noise and no thermal hysteresis | Single enable input; thermal shutdown lacks auto-recovery hysteresis | Prefer when higher PSRR is needed but system-level thermal management handles recovery |
Compared with XC6223D2818MR-G and RP512K2818-TR-F, MP2004DJ-MG-LF-P uniquely combines independent enable control, lowest output noise (95μVRMS), and auto-recovering thermal protection - making it optimal for space-constrained, battery-powered systems demanding clean, sequenced dual-rail power.

FAQ
What are the exact output voltages of MP2004DJ-MG-LF-P?
The MP2004DJ-MG-LF-P delivers fixed 2.8V on VOUT1 (Pin 6) and 1.8V on VOUT2 (Pin 1), factory-trimmed to ±1% accuracy across load, line, and temperature. These values are unchangeable via external resistors - the part is a fixed-output dual LDO, not adjustable.
Can MP2004DJ-MG-LF-P operate with a 2.5V input supplying 2.8V output?
No - the minimum input voltage required to maintain 2.8V output is 2.91V (2.8V + 110mV dropout at 100mA). At 200mA load, dropout rises to 250mV, requiring ≥3.05V input. Operation below 2.91V will cause VOUT1 to drop out of regulation.
Is an external Schottky diode required to prevent reverse current?
An external Schottky diode is recommended only if VOUT can exceed VIN by >0.3V (e.g., during hot-swap or backup-battery scenarios). The internal PMOS body diode conducts above ~0.7V forward bias; the Schottky clamps this to ~0.3V, preventing unintended discharge or misregulation.
What is the maximum allowable power dissipation at +85°C ambient?
Using θJA = 220°C/W and TJ(MAX) = 125°C, maximum continuous power dissipation at TA = +85°C is (125 − 85)/220 = 0.182W. Exceeding this causes thermal shutdown. Layout with ground-plane copper improves heat sinking and raises practical limits.
Does MP2004DJ-MG-LF-P require external compensation components?
No - the MP2004DJ-MG-LF-P is internally compensated and stable with 0.47–10μF ceramic output capacitors having ESR <1.2Ω. No external resistors, capacitors, or feedback networks are needed for basic operation.
How does the EN pin behavior affect system power sequencing?
EN1 and EN2 are independent active-high enables: pulling EN1 low disables only VOUT1 (2.8V), while EN2 low disables only VOUT2 (1.8V). This allows precise sequencing - e.g., powering VOUT2 first for I/O before enabling VOUT1 for core logic - without external timing circuitry.
What is the minimum recommended input capacitor value?
A minimum 0.47μF ceramic capacitor is required between VIN and GND, placed adjacent to Pin 5. Larger values (e.g., 2.2μF) improve line-transient response. Tantalum capacitors are acceptable but ceramic is preferred for ESR and reliability.
