Product details
Overview
MP2004DJ-JG-LF-Z 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, 95μVRMS output noise, and 69dB PSRR at 100Hz-designed for power-sensitive portable electronics requiring independent channel control.
For engineers reviewing the MP2004DJ-JG-LF-Z datasheet, MP2004DJ-JG-LF-Z pinout, MP2004DJ-JG-LF-Z application, or MP2004DJ-JG-LF-Z equivalent, key selection criteria include per-channel enable logic, ultra-low quiescent current (114μA), thermal shutdown behavior (140°C trip), dropout voltage (110mV at 100mA), and TSOT23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The MP2004DJ-JG-LF-Z integrates two independent PMOS-based LDOs sharing a common input and ground, each with dedicated active-high enable pins (EN1/EN2) enabling selective channel shutdown. Its architecture delivers fast transient response without requiring large output capacitors due to optimized internal compensation.
Each regulator maintains regulation across 2.5V–6.0V input while delivering stable 2.5V and 1.8V outputs with load regulation of ±1% over 1mA–200mA. Internal current limiting (450mA per channel) and thermal protection (140°C shutdown with 10°C hysteresis) ensure robust operation under fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.5V (Channel 1), 1.8V (Channel 2); fixed, factory-trimmed for precision biasing in multi-rail systems |
| Accuracy | ±1% over load (1–200mA) and temperature (−40°C to +85°C); ensures reliable core/logic voltage margins |
| PSRR | 69dB at 100Hz; suppresses low-frequency supply ripple critical for RF/analog subsystems |
| Noise | 95μVRMS (10Hz–100kHz); enables clean power for ADCs, PLLs, and RF receivers |
| Dropout Voltage | 110mV at 100mA load; supports operation down to VIN = VOUT + 0.11V, extending battery runtime |
| Quiescent Current | 114μA (both channels enabled, no load); minimizes standby power in always-on subsystems |
| Shutdown Current | 0.03–1μA (both EN pins low); enables deep-sleep modes in battery-powered devices |
Pinout & Package
MP2004DJ-JG-LF-Z is housed in a 6-pin TSOT23-6 package (0.95mm pitch, 2.8mm × 2.9mm footprint) with exposed pad not electrically connected. Thermal performance relies on GND pin connection to a large copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT2 | Channel 2 regulated output | Delivers fixed 1.8V to low-voltage logic cores; requires local 0.47–10μF ceramic capacitor |
| 2 - GND | Common analog/digital ground reference | Mandatory low-impedance connection to PCB ground plane for noise suppression and thermal dissipation |
| 3 - EN2 | Active-high enable for Channel 2 | Pull high to enable 1.8V output; must not float-tie to VIN or controller GPIO |
| 4 - EN1 | Active-high enable for Channel 1 | Independent control of 2.5V rail; enables dynamic power sequencing in multi-voltage systems |
| 5 - VIN | Input supply for both regulators | Accepts 2.5–6.0V; requires ≥0.47μF input ceramic capacitor close to pin |
| 6 - VOUT1 | Channel 1 regulated output | Delivers fixed 2.5V to analog sensors or I/O interfaces; shares stability requirements with VOUT2 |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enables | EN1/EN2 allow staggered power-up, selective rail shutdown, and flexible sequencing without external logic |
| Ultra-low noise output | 95μVRMS enables direct powering of noise-sensitive analog blocks without additional filtering |
| High PSRR at low frequency | 69dB at 100Hz rejects switching noise from upstream DC/DC converters feeding VIN |
| Low dropout with PMOS pass element | 110mV dropout at 100mA permits operation from single-cell Li-ion (3.0V min) while maintaining 2.5V/1.8V rails |
| Integrated protection | Per-channel current limit (450mA) and junction thermal shutdown (140°C) prevent damage during overload or poor heatsinking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6221B2518MR-G | Same TSOT23-6 package; 2.5V/1.8V outputs; but higher 250μA IQ and 150mV dropout at 100mA | Lacks independent EN pins-uses single enable for both channels; no thermal shutdown hysteresis spec | Choose when lower cost outweighs need for per-rail control and ultra-low IQ |
| Richtek RT9013-2518GB | 2.5V/1.8V outputs; 120μA IQ; but only 55dB PSRR at 100Hz and 120mV dropout at 100mA | Single enable pin; no guaranteed current limit spec; thermal shutdown threshold unspecified | Acceptable where PSRR >60dB is sufficient and sequencing flexibility is not required |
Compared with XC6221B2518MR-G and RT9013-2518GB, MP2004DJ-JG-LF-Z provides superior noise performance (95μVRMS vs. ≥120μVRMS), tighter accuracy (±1% vs. ±2%), and true per-channel enable control-critical for dynamic power management in portable systems.

FAQ
What is the maximum input voltage rating for MP2004DJ-JG-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 to the internal PMOS pass elements and protection circuitry. Operation above 6.0V voids parametric guarantees including dropout, PSRR, and thermal shutdown accuracy.
Can MP2004DJ-JG-LF-Z operate with ceramic output capacitors below 1μF?
Yes-MP2004DJ-JG-LF-Z is stable with ceramic capacitors as low as 0.47μF and ESR <1.2Ω. The datasheet confirms stability across 0.47–10μF, enabling use of small 0402/0603 case sizes. Lower capacitance increases transient voltage deviation but remains within specification for typical 0–80mA load steps.
Is there reverse current protection built into MP2004DJ-JG-LF-Z?
No-the internal PMOS pass device includes a body diode that conducts if VOUT exceeds VIN by >0.7V. To prevent reverse current, an external Schottky diode (e.g., Diodes Inc. AP7165) must be placed in series with VIN or in parallel with the body diode as shown in Figure 4 of the datasheet.
How does thermal shutdown behave during sustained overload?
When junction temperature reaches 140°C, both LDOs shut down simultaneously. After cooldown of 10°C (to ~130°C), the device auto-restarts. This hiccup-mode cycling limits average power dissipation but requires careful PCB thermal design-especially GND pad copper area-to avoid repeated tripping under continuous 200mA load at high ambient temperatures.
What is the minimum load current required for regulation stability?
No minimum load is required-MP2004DJ-JG-LF-Z maintains regulation from 0mA to 200mA per channel. Quiescent current remains stable at 114μA (both channels enabled), and output voltage accuracy holds at ±1% even at zero load, confirmed across −40°C to +85°C.
Are the EN1 and EN2 pins 5V-tolerant?
Yes-EN1 and EN2 accept input voltages up to 6.0V regardless of VIN level. The enable threshold is VIH = 1.6V (min) and VIL = 0.45V (max), with input bias current ≤300nA. This allows direct interfacing with 3.3V or 5V GPIOs without level-shifting.
Does MP2004DJ-JG-LF-Z support adjustable output voltages?
No-MP2004DJ-JG-LF-Z has factory-trimmed fixed outputs: 2.5V on VOUT1 and 1.8V on VOUT2. Adjustable versions (e.g., MP2004DJ-XX-LF-Z with different top markings) exist for other voltage combinations, but this specific part number is not programmable or resistor-configurable.
