Product details
Overview
MP2004DJ-ZS-LF-Z from Monolithic Power Systems is a dual-channel, low-noise, high-PSRR linear regulator with fixed 5.0V and 3.3V 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-ZS-LF-Z datasheet, MP2004DJ-ZS-LF-Z pinout, MP2004DJ-ZS-LF-Z application, or MP2004DJ-ZS-LF-Z 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 MP2004DJ-ZS-LF-Z integrates two independent LDO regulators sharing a common ground and input supply but featuring separate EN pins and output voltages-5.0V on Channel 1 (VOUT1) and 3.3V on Channel 2 (VOUT2). Each channel employs a PMOS pass element, delivering 110mV dropout at 100mA load and maintaining regulation down to 2.5V input.
Its architecture supports fast transient response with ceramic output capacitors as low as 0.47µF (ESR <1.2Ω), while built-in current limiting (450mA per channel) and thermal protection (140°C trip with 10°C hysteresis) ensure robust operation under fault conditions without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 5.0V (Ch1) and 3.3V (Ch2), fixed, ±1% accuracy over load/temperature |
| Max Output Current | 200mA per channel continuous; enables dual-rail powering of core + I/O domains |
| PSRR @100Hz | 69dB - suppresses low-frequency supply ripple critical for RF/analog subsystems |
| Output Noise | 95μVRMS (10Hz–100kHz) - suitable for noise-sensitive analog circuits and ADC references |
| Dropout Voltage | 110mV at 100mA - allows operation with minimal headroom (e.g., 3.4V input for 3.3V rail) |
| Quiescent Current | 114μA (both channels active, no load) - extends battery life in always-on subsystems |
| Shutdown Current | 0.03–1μA - near-zero power state when both EN pins grounded |
Pinout & Package
MP2004DJ-ZS-LF-Z is housed in a 6-pin TSOT23 package (JEDEC MO-193 AB), with exposed pad not electrically connected. Pin spacing is 0.95mm pitch; recommended land pattern includes 2.6–3.0mm length and 1.5–1.7mm width pads for reliable reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT2 | Channel 2 regulated output | Delivers fixed 3.3V; requires local 0.47–10µF ceramic capacitor for stability |
| 2 - GND | Common analog/digital ground reference | Must connect to large copper area to reduce thermal resistance (θJA = 220°C/W) |
| 3 - EN2 | Active-high enable for Channel 2 | Pull high to enable 3.3V output; must not float - tie to VIN or logic controller |
| 4 - EN1 | Active-high enable for Channel 1 | Independent control of 5.0V rail; enables power sequencing or dynamic rail disabling |
| 5 - VIN | Input supply for both regulators | Accepts 2.5–6.0V; requires ≥0.47µF ceramic input capacitor close to pin |
| 6 - VOUT1 | Channel 1 regulated output | Delivers fixed 5.0V; shares same stability requirements as VOUT2 |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 allow asynchronous startup/shutdown of 5.0V and 3.3V rails for precise power sequencing |
| Ultra-low output noise | 95μVRMS enables clean biasing of precision op-amps, RF ICs, and high-resolution ADCs |
| High PSRR at low frequency | 69dB at 100Hz rejects switching noise from upstream DC/DC converters |
| Thermal shutdown with hysteresis | 140°C trip + 10°C hysteresis prevents thermal cycling and ensures safe recovery |
| PMOS pass architecture | Eliminates reverse-current path risk unless external Schottky is added for back-powering scenarios |

FAQ
What are the exact output voltages of MP2004DJ-ZS-LF-Z?
The MP2004DJ-ZS-LF-Z provides fixed 5.0V on VOUT1 (Pin 6) and 3.3V on VOUT2 (Pin 1), both with ±1% accuracy across load, line, and temperature. These values are laser-trimmed during manufacturing and cannot be adjusted externally.
Can MP2004DJ-ZS-LF-Z operate with a 2.5V input supplying the 3.3V output?
No - the minimum input voltage required to regulate 3.3V is 3.41V (3.3V + 110mV dropout). At 2.5V input, the 3.3V channel drops out of regulation. The 5.0V channel requires ≥5.11V input and will also be unregulated at 2.5V.
Is an external Schottky diode required for reverse-current protection?
Yes, if VOUT exceeds VIN by >0.3V (e.g., during hot-swap or backup power scenarios), the internal PMOS body diode conducts. An external Schottky (anode to VIN, cathode to VOUT) limits reverse current and prevents misoperation or damage.
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 is (125 − 85)/220 = 182mW. Exceeding this causes thermal shutdown; layout with ground-plane copper improves heat sinking.
Does MP2004DJ-ZS-LF-Z support output capacitor ESR outside the 0–1.2Ω range?
No - stability is guaranteed only with ceramic output capacitors having ESR ≤1.2Ω and capacitance between 0.47µF and 10µF. Tantalum or aluminum electrolytics with higher ESR may cause oscillation or poor transient response.
How does the EN pin logic behave during power-up?
EN1 and EN2 are active-high with VIH = 1.6V min and VIL = 0.45V max. To ensure predictable startup, drive EN pins after VIN reaches ≥2.5V; floating EN pins is prohibited and may cause erratic output behavior.
What is the load-transient voltage spike magnitude for a 0–80mA step?
Typical output voltage transient spike is tens of millivolts (e.g., ~30mV) with 2.2µF ceramic output capacitors. Reducing ESR or increasing capacitance further lowers peak deviation, per the load-transient design guidelines in the datasheet.
