Product details
Overview
MP2004DJ-ZS-LF-P 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 - used in battery-powered handheld equipment requiring independent, low-quiescent-power voltage rails.
For engineers reviewing the MP2004DJ-ZS-LF-P datasheet, MP2004DJ-ZS-LF-P pinout, MP2004DJ-ZS-LF-P application, or MP2004DJ-ZS-LF-P equivalent, key selection criteria include dual independent enable control (EN1/EN2), 69dB PSRR at 100Hz, 110mV dropout at 100mA, thermal shutdown at 140°C, and TSOT23-6 package compatibility with space-constrained portable designs.
Technical Context
The MP2004DJ-ZS-LF-P integrates two independent PMOS-based LDOs with separate enable inputs (EN1/EN2), enabling asynchronous power sequencing and ultra-low shutdown current (≤1μA). Each channel features internal current limiting (450mA trip) and thermal shutdown with 10°C hysteresis.
Its architecture delivers fast transient response using only 2.2μF ceramic output capacitors, supported by low 114μA quiescent current (both channels active) and stable operation down to 0.47μF output capacitance - critical for compact, battery-sensitive applications like netbooks and cellular handsets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 5.0V (Channel 1), 3.3V (Channel 2) - fixed, factory-trimmed outputs eliminating external feedback resistors |
| Output Accuracy | ±1% over load (1–200mA) and temperature (−40°C to +85°C) - ensures stable logic rail compliance |
| PSRR | 69dB at 100Hz - suppresses low-frequency supply ripple from noisy DC-DC stages or battery sources |
| Output Noise | 95μVRMS (10Hz–100kHz) - suitable for noise-sensitive analog/RF circuitry without additional filtering |
| Dropout Voltage | 110mV at 100mA load - enables regulation from 3.4V input for 3.3V rail, extending battery runtime |
| Quiescent Current | 114μA (both LDOs enabled, no load) - minimizes standby power in always-on subsystems |
| Shutdown Current | 0.03–1μA (EN1=EN2=GND) - supports deep-sleep modes in portable devices |
Pinout & Package
MP2004DJ-ZS-LF-P is housed in a 6-pin TSOT23 package (JEDEC MO-193 AB), with exposed pad not electrically connected. Pin spacing is 0.95mm pitch; total footprint 2.80×2.60mm. Thermal resistance θJA = 220°C/W on 4-layer board.
| 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 and transient response |
| 2 - GND | Common ground reference | Must connect to large copper area or ground plane to reduce thermal resistance and improve PSRR |
| 3 - EN2 | Active-high enable for Channel 2 | Pull high to VIN to activate 3.3V rail; tie low to disable independently - no floating allowed |
| 4 - EN1 | Active-high enable for Channel 1 | Pull high to VIN to activate 5.0V rail; enables flexible power sequencing and system-level sleep control |
| 5 - VIN | Input supply pin | Accepts 2.5–6.0V; requires ≥0.47μF ceramic input capacitor close to pin for line transient immunity |
| 6 - VOUT1 | Channel 1 regulated output | Delivers fixed 5.0V; shares same stability requirements as VOUT2 but operates at higher voltage headroom |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable control | EN1 and EN2 allow asynchronous startup/shutdown of 5.0V and 3.3V rails - essential for FPGA I/O bank sequencing and low-power mode partitioning |
| Ultra-low noise output | 95μVRMS (10Hz–100kHz) - eliminates need for post-regulator LC filters in audio codec or ADC reference supplies |
| High PSRR at low frequency | 69dB at 100Hz - rejects ripple from switching converters operating near audio band without added compensation |
| Thermal protection with hysteresis | Shuts down at 140°C; re-enables at 130°C - prevents latch-up during sustained overload while allowing recovery without system reset |
| Low dropout with PMOS pass element | 110mV at 100mA - sustains regulation under brownout conditions where input drops to within 110mV of output |
Applications
| Cellular Phone Baseband | Laptop USB-C PD Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6221B335MR-G | Single-output (3.3V only), no 5.0V channel; 60dB PSRR at 100Hz; 40μVRMS noise | Requires separate 5.0V regulator; better noise performance but lacks dual-rail integration | Select when ultra-low noise dominates over rail count and board space is constrained |
| Analog Devices ADM7150ACPZ-3.3-R7 | Single-channel, 3.3V only; 1.2μVRMS noise; 80dB PSRR at 100Hz; 800mA output | No 5.0V output; higher cost and larger 8-lead LFCSP package; over-specified current capacity | Select when noise-critical 3.3V rail demands sub-μV performance and second rail is handled elsewhere |
Compared with XC6221B335MR-G and ADM7150ACPZ-3.3-R7, MP2004DJ-ZS-LF-P uniquely delivers matched 5.0V/3.3V outputs in one TSOT23-6 package with balanced PSRR/noise trade-offs - reducing BOM count and PCB area while meeting mid-tier portable device requirements.

FAQ
What are the exact output voltages programmed in MP2004DJ-ZS-LF-P?
The MP2004DJ-ZS-LF-P is factory-configured with fixed 5.0V on VOUT1 (Pin 6) and 3.3V on VOUT2 (Pin 1). These values are laser-trimmed during production and cannot be adjusted externally - confirmed by the "ZS" top marking code in the ordering guide and electrical characteristics table.
Does MP2004DJ-ZS-LF-P require external capacitors, and what are the minimum values?
Yes: a minimum 0.47μF ceramic capacitor is required on VIN (Pin 5), and separate 0.47–10μF ceramic capacitors must be placed on VOUT1 (Pin 6) and VOUT2 (Pin 1). ESR must be below 1.2Ω. Larger values improve transient response but increase board area - verified in the Application Information section.
How does the thermal shutdown behave, and can it be disabled?
Thermal shutdown activates at 140°C junction temperature and auto-recovers at 130°C (10°C hysteresis). It is fully internal, non-adjustable, and cannot be disabled - a hardwired safety feature documented in the Operation section and Absolute Maximum Ratings table.
Can EN1 and EN2 be tied together, and what happens if left floating?
EN1 and EN2 may be tied together for simultaneous control, but neither pin must be left floating - doing so risks undefined output states and potential damage. The datasheet explicitly states "Do Not Float This Pin" for both EN1 and EN2 in the PIN FUNCTIONS table.
Is MP2004DJ-ZS-LF-P compatible with lead-free reflow processes?
Yes: the "-LF" suffix confirms RoHS-compliant, lead-free termination, and the "-Z" suffix indicates tape-and-reel packaging. The Absolute Maximum Ratings specify a 260°C lead temperature for 10 seconds - fully compatible with standard Pb-free reflow profiles per J-STD-020.
What is the maximum allowable input voltage, and what happens above it?
The absolute maximum input voltage is 6.5V. Exceeding this rating - even briefly - may cause permanent damage, as stated in the Absolute Maximum Ratings table. Operation above 6.0V (recommended max) degrades PSRR and increases dropout, but the device remains functional until the 6.5V limit is breached.
Does MP2004DJ-ZS-LF-P support reverse current protection?
No: the internal PMOS pass element includes a body diode that conducts if VOUT > VIN by >0.7V. The datasheet recommends adding an external Schottky diode across each output to block reverse current - detailed in the "Reverse Current Path" section on page 7.
