Product details
Overview
MP2004DJ-SJ-LF-Z from Monolithic Power Systems is a dual-channel, low-noise, high-PSRR linear regulator with fixed 3.3V and 2.5V outputs, ±1% accuracy, 200mA per channel output capability, and 95μVRMS output noise - designed for powering sensitive analog and RF circuitry in portable electronics.
For engineers reviewing the MP2004DJ-SJ-LF-Z datasheet, MP2004DJ-SJ-LF-Z pinout, MP2004DJ-SJ-LF-Z application, or MP2004DJ-SJ-LF-Z equivalent, key selection criteria include independent enable control per channel, ultra-low dropout (110mV at 100mA), thermal shutdown at 140°C, and TSOT23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The MP2004DJ-SJ-LF-Z integrates two independent PMOS-based LDOs with separate EN1/EN2 inputs, enabling selective power sequencing and dynamic power gating. Each regulator maintains regulation down to 110mV dropout and delivers 69dB PSRR at 100Hz with 2.2μF ceramic output capacitors.
It features internal current limiting (450mA per channel), thermal shutdown with 10°C hysteresis, and <114μA quiescent current when both channels are active - optimized for battery-powered systems requiring low standby power and fast transient response without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.3V (Channel 1) and 2.5V (Channel 2), fixed, ±1% accuracy over load/temperature |
| Max Output Current | 200mA per channel - supports dual-rail microcontroller cores or mixed-signal SoCs |
| PSRR @ 100Hz | 69dB - suppresses switching noise from upstream DC/DC converters feeding the LDO input |
| Output Noise | 95μVRMS (10Hz–100kHz) - suitable for RF transceivers and precision ADC/DAC reference supplies |
| Dropout Voltage | 110mV at 100mA load - enables operation from single-cell Li-ion (3.0V min) or 3.3V rail with margin |
| Quiescent Current | 114μA (both LDOs enabled, no load) - extends battery life in always-on sensor nodes |
| Shutdown Current | 0.03–1μA (both EN pins low) - meets ultra-low-power sleep mode requirements |
Pinout & Package
MP2004DJ-SJ-LF-Z is housed in a 6-pin TSOT23-6 package (JEDEC MO-193 AB), with exposed pad not electrically connected. Pin 1 (VOUT2) is bottom-left when reading top marking left-to-right; GND (Pin 2) provides common return path and thermal conduction to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT2 | Channel 2 regulated output | Delivers fixed 2.5V supply; requires local 0.47–10μF ceramic capacitor with ESR <1.2Ω |
| 2 - GND | Common ground reference | Must connect to large copper area for thermal dissipation and noise rejection |
| 3 - EN2 | Channel 2 enable input (active-high) | Logic-high ≥1.6V enables VOUT2; must not float - tie to VIN or controller GPIO |
| 4 - EN1 | Channel 1 enable input (active-high) | Independent control of 3.3V rail; supports power sequencing and fault isolation |
| 5 - VIN | Input supply pin | Accepts 2.5–6.0V; requires ≥0.47μF input ceramic capacitor close to pin |
| 6 - VOUT1 | Channel 1 regulated output | Delivers fixed 3.3V supply; decoupling identical to VOUT2 |

FAQ
What are the exact output voltages programmed in MP2004DJ-SJ-LF-Z?
The MP2004DJ-SJ-LF-Z is factory-configured with fixed 3.3V on Channel 1 (VOUT1, Pin 6) and 2.5V on Channel 2 (VOUT2, Pin 1). These values are laser-trimmed during production and cannot be adjusted externally. The ordering guide confirms "SJ" maps to 3.3V/2.5V per the standard code table.
Can MP2004DJ-SJ-LF-Z 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 output channel reaches dropout - meaning regulation is no longer guaranteed. For reliable 2.5V output, VIN must exceed 2.61V (2.5V + 110mV dropout).
Is the GND pin internally connected to the die substrate or exposed pad?
The TSOT23-6 package has no electrically connected exposed pad. Pin 2 (GND) is the sole ground connection and must be soldered to a PCB ground plane for thermal conduction and noise immunity. Thermal resistance θJA = 220°C/W assumes proper GND pad layout per JEDEC MO-193 AB guidelines.
Does MP2004DJ-SJ-LF-Z require external compensation components?
No. The MP2004DJ-SJ-LF-Z is internally compensated and stable with ceramic output capacitors from 0.47μF to 10μF and ESR ≤1.2Ω. Adding external RC networks or tantalum capacitors may degrade transient response or cause instability per the Application Information section.
How does the current limit behave during simultaneous overload on both channels?
Each channel has an independent current limit structure. If both outputs exceed 200mA, both LDOs enter current-limit mode simultaneously - maintaining regulated voltage until thermal shutdown activates at junction temperatures exceeding 140°C. The 450mA short-circuit limit is per channel, not total.
What is the maximum allowable input voltage for continuous operation?
The Absolute Maximum Rating specifies 6.5V, but the Recommended Operating Condition limits continuous input to 6.0V. Operation at 6.5V is only allowed transiently (e.g., during load dump). Sustained 6.0V input is safe provided power dissipation remains within the 0.45W limit at ambient temperature.
Can EN1 and EN2 be tied together for synchronous enable/disable?
Yes. EN1 and EN2 are independently buffered logic inputs with identical thresholds (VIH = 1.6V, VIL = 0.45V). They may be driven by the same GPIO or logic signal without interference. However, tying them forfeits independent channel control - a key feature for power sequencing in complex systems.
