Product details
Overview
MP2004DJ-JG-LF-P from Monolithic Power Systems is a dual-channel, low-noise, high-PSRR linear regulator with fixed 2.5V and 1.8V outputs, ±1% accuracy, 200mA per channel output capability, and 95μVRMS output noise. It operates from 2.5V to 6.0V input and uses internal PMOS pass devices for ultra-low dropout (110mV at 100mA), enabling use in battery-powered handheld equipment requiring stable dual-rail power.
For engineers reviewing the MP2004DJ-JG-LF-P datasheet, MP2004DJ-JG-LF-P pinout, MP2004DJ-JG-LF-P application, or MP2004DJ-JG-LF-P equivalent, key selection criteria include independent enable control (EN1/EN2), thermal shutdown at 140°C, 69dB PSRR at 100Hz, and TSOT23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The MP2004 integrates two independent LDO regulators sharing a common ground but featuring separate EN pins and output terminals. Each channel employs a PMOS pass element with inherent reverse-current protection considerations, requiring external Schottky diodes in back-powering scenarios.
Its architecture delivers fast transient response using small ceramic output capacitors (0.47–10μF, ESR <1.2Ω), supported by 114μA quiescent current (both channels active) and shutdown current of ≤1μA - critical for extended battery life in portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage (Ch1/Ch2) | 2.5V / 1.8V fixed - eliminates external feedback resistors and ensures precise rail generation for core/logic voltage domains. |
| Output Accuracy | ±1% over load/temperature - guarantees stable operation of sensitive analog and digital circuitry without calibration. |
| Max Output Current | 200mA per channel - supports moderate-power subsystems like RF transceivers or sensor interfaces without external boost stages. |
| PSRR @ 100Hz | 69dB - suppresses switching noise from upstream DC/DC converters, preserving signal integrity in mixed-signal applications. |
| Output Noise | 95μVRMS (10Hz–100kHz) - meets low-noise requirements for ADC references, audio codecs, and precision analog front-ends. |
| Dropout Voltage | 110mV @ 100mA - enables regulation from 2.61V input to 2.5V rail, maximizing usable battery voltage range in single-cell Li-ion designs. |
| Quiescent Current | 114μA (both LDOs on) - minimizes standby power loss, extending operational time in always-on monitoring nodes. |
Pinout & Package
MP2004DJ-JG-LF-P is housed in a 6-pin TSOT23 package (JEDEC MO-193 AB), with exposed pad not electrically connected. The compact 2.9mm × 1.6mm footprint supports high-density portable PCB layouts while maintaining thermal performance via GND-connected copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT2 | Channel 2 regulated output | Provides fixed 1.8V supply; requires local 2.2μF ceramic capacitor for stability and transient response. |
| 2 - GND | Common ground reference | Must connect to large copper pour for thermal dissipation and low-impedance return path to minimize noise coupling. |
| 3 - EN2 | Active-high enable for Channel 2 | Logic-high ≥1.6V enables 1.8V output; must not float - tie to VIN or controller GPIO for controlled sequencing. |
| 4 - EN1 | Active-high enable for Channel 1 | Independent control of 2.5V rail; allows staggered power-up or dynamic rail disabling during low-power modes. |
| 5 - VIN | Input supply pin | Accepts 2.5–6.0V; requires ≥0.47μF ceramic input capacitor close to pin to suppress line transients. |
| 6 - VOUT1 | Channel 1 regulated output | Delivers fixed 2.5V; shares same noise/PSRR specs as VOUT2 but operates independently under EN1 control. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 allow sequenced or isolated activation of 2.5V and 1.8V rails - essential for FPGA I/O/core power sequencing and low-power sleep mode control. |
| Ultra-low output noise | 95μVRMS enables direct powering of noise-sensitive analog circuits (e.g., PLL VCO supplies, SAR ADC references) without additional filtering. |
| High PSRR at low frequency | 69dB at 100Hz rejects ripple from buck converter switching frequencies and their harmonics - critical in multi-rail SMPS-based systems. |
| Thermal shutdown with hysteresis | Triggers at 140°C with 10°C hysteresis - prevents thermal runaway during overload while allowing automatic recovery after cooling, improving system robustness. |
| Low dropout with PMOS pass device | 110mV dropout at 100mA permits operation down to ~2.61V input for 2.5V rail - extends usable capacity of 3.0V nominal batteries. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What are the exact output voltages of MP2004DJ-JG-LF-P?
The MP2004DJ-JG-LF-P provides fixed 2.5V on VOUT1 (Pin 6) and 1.8V on VOUT2 (Pin 1), as defined by its JG top marking code per MPS's Output Voltage Selector Guide. These values are trimmed to ±1% accuracy across temperature and load, with no external resistor network required.
Does MP2004DJ-JG-LF-P require external compensation components?
No - the MP2004DJ-JG-LF-P is internally compensated and designed to be stable with ceramic output capacitors ranging from 0.47μF to 10μF and ESR below 1.2Ω. Adding external RC networks or ferrite beads is unnecessary and may degrade transient response or stability.
Can MP2004DJ-JG-LF-P operate with input voltage below 2.5V?
No - the absolute minimum recommended input voltage is 2.5V per the datasheet's Recommended Operating Conditions. At 2.5V input, the 2.5V rail cannot regulate (zero dropout margin); practical operation requires VIN ≥ VOUT + dropout voltage (e.g., ≥2.61V for 2.5V output at 100mA).
How should the EN pins be handled if only one channel is used?
If only one channel is needed, the unused EN pin must not be left floating. Tie it to VIN to keep that regulator enabled, or to GND to disable it permanently. Floating EN pins cause unpredictable output states and increased leakage due to internal biasing uncertainty.
Is there reverse current protection built into MP2004DJ-JG-LF-P?
The MP2004DJ-JG-LF-P uses PMOS pass devices with inherent body diodes from OUT to IN. This allows reverse current flow if VOUT > VIN + 0.7V. For bidirectional systems, an external Schottky diode (anode to GND, cathode to OUT) is required to block reverse conduction and prevent misoperation.
What is the thermal resistance (θJA) of the TSOT23-6 package under standard conditions?
The datasheet specifies θJA = 220°C/W for the TSOT23-6 package on a JEDEC JESD51-7 4-layer board. Actual thermal performance improves significantly with a dedicated GND thermal pad connected to ≥1 cm² copper area - reducing effective θJA by up to 40% in optimized layouts.
Does MP2004DJ-JG-LF-P support adjustable output voltages?
No - MP2004DJ-JG-LF-P is a fixed-output variant. Adjustable versions (e.g., MP2004DJ-XX-LF-Z with external feedback) are not offered. For programmable outputs, consider MPS's MP2013 or MPQ2013 families, which support external resistor dividers and wider VOUT ranges.
