Product details
Overview
MP8801DJ-2.5-LF-Z from Monolithic Power Systems is a fixed-output, low-noise, low-dropout linear regulator delivering 2.5V ±2% at up to 150mA load current with 100mV dropout at 100mA, 70dB PSRR at 1kHz, and 125μA ground current. It operates from 2.7V–6.5V input and targets noise-sensitive analog power rails such as mobile handset PLL VCO supplies and audio codec biasing.
For engineers reviewing the MP8801DJ-2.5-LF-Z datasheet, MP8801DJ-2.5-LF-Z pinout, MP8801DJ-2.5-LF-Z application, or MP8801DJ-2.5-LF-Z equivalent, key selection criteria include output accuracy over temperature, PSRR performance at RF frequencies, thermal shutdown threshold (155°C), dropout behavior under full load, and compatibility with low-ESR ceramic output capacitors.
Technical Context
The MP8801DJ-2.5-LF-Z uses a PMOS pass transistor architecture enabling low dropout and high PSRR without requiring an external bypass capacitor for stability. Its internal 2.5V reference is trimmed to ±2% accuracy across –40°C to +85°C, and feedback is referenced to a precise 1.222V FB threshold.
Enable control is implemented via a TTL-compatible EN pin (VIH = 1.5V, VIL = 0.4V), supporting automatic startup when tied to IN. Thermal shutdown activates at 155°C with 30°C hysteresis, and the device remains stable with 1μF–10μF X5R/X7R ceramic output capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5V ±2% (2.45V–2.55V) at TA = 25°C; maintains accuracy across –40°C to +85°C |
| Max Output Current | 150mA continuous load capability with thermal protection limiting sustained dissipation |
| Dropout Voltage | 100mV at 100mA load ensures regulation down to VIN = 2.6V for 2.5V output |
| PSRR | 70dB at 1kHz and 30dB at 1MHz enables effective suppression of switching noise in mixed-signal systems |
| Ground Current | 125μA typical at 1mA load; increases only marginally to 150μA at 150mA, minimizing quiescent power loss |
| Output Noise | 300nV/√Hz at 1kHz supports low-phase-noise PLL and high-SNR audio applications |
| Input Voltage Range | 2.7V to 6.5V operation accommodates single-cell Li-ion, USB, or regulated DC-DC outputs |
Pinout & Package
MP8801DJ-2.5-LF-Z is housed in a TSOT23-5 package (2.9mm × 1.6mm × 1.0mm, 0.95mm pitch), optimized for space-constrained portable designs and thermally enhanced via exposed pad connection to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Power input | Supplies pass transistor source; requires ≥1μF ceramic bypass to GND for stability and transient response |
| 2 GND | Ground reference | Common return for all internal circuitry; must be connected to low-impedance system ground plane |
| 3 EN | Enable control | TTL-compatible digital input; high ≥1.5V enables regulation, low ≤0.4V disables output and reduces shutdown current to ≤1μA |
| 4 FB | Feedback sense | Monitors output via internal 2.5V divider; not used in fixed-output mode but accessible for adjustment if required |
| 5 OUT | Regulated output | Delivers clean 2.5V supply; requires ≥1μF ceramic bypass to GND for ESR-dependent stability and noise filtering |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise regulation | 300nV/√Hz output noise enables direct powering of VCOs and microphone preamps without added filtering |
| High PSRR at RF | 30dB rejection at 1MHz suppresses switching regulator ripple from adjacent DC-DC converters |
| Thermal robustness | 155°C shutdown with 30°C hysteresis prevents latch-up during momentary overload or poor heatsinking |
| Load regulation precision | 0.001%/mA variation ensures stable voltage across full 0–150mA load range, critical for ADC reference rails |
| Low-ESR capacitor support | Stable with 1μF–10μF X5R/X7R ceramics eliminates need for costly tantalum or polymer capacitors |

FAQ
What is the maximum allowable input voltage for MP8801DJ-2.5-LF-Z?
The absolute maximum input voltage is +7V, but the recommended operating range is 2.7V to 6.5V. Exceeding 6.5V risks exceeding the 0.56W power dissipation limit at ambient temperatures above 25°C and may trigger thermal shutdown prematurely. Operation above 6.5V voids guaranteed specifications.
Can MP8801DJ-2.5-LF-Z be used in adjustable-output configuration?
Yes - although configured as a 2.5V fixed-output device, its FB pin is accessible and compatible with external resistor dividers. The internal 2.5V setting can be overridden to deliver any output from 1.25V to 5V using R1/R2 per Equation (1), with VFB = 1.222V as the feedback threshold.
Is a feed-forward capacitor required for stable operation?
No - the MP8801DJ-2.5-LF-Z is stable with only 1μF–10μF ceramic output capacitors and does not require a feed-forward capacitor. However, adding a 100nF ceramic capacitor in parallel with R1 improves transient response in adjustable configurations; it is optional and unnecessary for fixed 2.5V use.
What is the thermal resistance (θJA) of the TSOT23-5 package?
The junction-to-ambient thermal resistance (θJA) for the TSOT23-5 package is 220°C/W under JEDEC JESD51-7 4-layer PCB conditions. This value assumes standard copper layout; actual θJA improves significantly with larger thermal pads and internal copper planes, enabling 150mA operation up to +85°C ambient.
Does MP8801DJ-2.5-LF-Z support automatic startup without external components?
Yes - connecting the EN pin directly to the IN pin enables automatic startup at power-on. No pull-up resistor is needed because the EN pin has no internal pull-up; tying EN to IN ensures immediate enablement once VIN exceeds ~2.7V, simplifying design for always-on analog rails.
How does load regulation performance impact ADC reference stability?
With load regulation of ≤0.001%/mA, the MP8801DJ-2.5-LF-Z varies less than 150μV across its full 0–150mA load range. This ensures sub-LSB drift for 16-bit ADCs referenced to its output, preserving measurement accuracy without additional post-regulation filtering or trimming.
