Product details

Overview

MP8200DT-LF-P from Monolithic Power Systems is a 1.0V precision shunt voltage regulator in SOT23-3 package, designed as a low-voltage reference with ±1% initial accuracy, 0.5Ω dynamic output resistance, and 100µA to 10mA operating current range. It operates from 1V to 12V input, supports battery-powered instrumentation and portable electronics, and requires no external capacitor for stability.

For engineers reviewing the MP8200DT-LF-P datasheet, MP8200DT-LF-P pinout, MP8200DT-LF-P application, or MP8200DT-LF-P equivalent, key selection criteria include its 1.0V fixed output, ultra-low dynamic impedance, sharp turn-on behavior, temperature coefficient of 85 ppm/°C over –40°C to +85°C, and compatibility with adjustable reference designs using external op-amps.

Technical Context

The MP8200DT-LF-P implements a precision bandgap-based shunt regulation architecture with internal trimming for 1.0V nominal output. Its functional block includes a reference voltage generator, error amplifier, and output stage configured as a two-terminal cathode-anode device with TRIM pin unused.

It delivers stable regulation without external capacitance across its full 1V–12V input range and maintains output accuracy under load current variations from 100µA to 10mA. The device exhibits 10µs turn-on settling time within 0.1% and 4µV_p-p noise (0.1Hz–10Hz), enabling high-resolution analog measurement systems.

Use Scenario: Portable handheld multimeter with dual-slope integration and auto-ranging analog signal chain.

IC Role / Device Role / Timing Role: Primary voltage reference for integrator capacitor charging and ADC reference rail.

Use Value: 0.5Ω dynamic resistance prevents gain error drift during input step transients up to 10mA load variation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar shunt voltage reference applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MP8201DT-LF-Z	Successor part with improved 0.5% initial accuracy, lower 0.3Ω dynamic resistance, and extended –40°C to +125°C rating	Required for new designs targeting automotive or extended-temperature industrial use	Select MP8201 for production releases needing enhanced accuracy, wider temp range, or long-term MPS support
TLVH431IDBVR	Adjustable 1.24V reference with 0.5% accuracy; requires external resistors to set 1.0V; 0.7Ω dynamic resistance	Used where programmability or higher reference voltage flexibility is needed	Choose TLVH431 only if system already uses adjustable topology and 1.24V base reference is acceptable

Compared with MP8200DT-LF-P, MP8201DT-LF-Z offers tighter accuracy and broader temperature capability for future-proofing, while TLVH431IDBVR trades fixed 1.0V simplicity for configurability-making MP8200 optimal for cost-sensitive, space-constrained 1.0V reference needs where legacy design continuity is required.

Manufacturer

Monolithic Power Systems (MPS) is a fabless semiconductor company specializing in high-performance analog and power ICs, headquartered in California and serving global power management markets since 1997.

The MP8200 belongs to MPS's precision shunt voltage reference product line, engineered specifically for ultra-low-voltage (1.0V), low-quiescent-current applications in portable and instrumentation systems where size, noise, and thermal stability are critical.

FAQ

What is the maximum input voltage the MP8200DT-LF-P can withstand?

The MP8200DT-LF-P supports continuous operation up to 12V input, with absolute maximum reverse current rated at 25mA. Exceeding 12V risks exceeding the 0.52W power dissipation limit at room temperature, potentially triggering thermal shutdown. Designers must size RBIAS to limit current under worst-case VIN and load conditions.

Can the TRIM pin be used to adjust output voltage?

No-the TRIM pin (Pin 3) is internally unconnected and must remain floating or tied to V–. Output voltage adjustment requires external circuitry such as an op-amp feedback network; the MP8200 itself provides only a fixed 1.0V reference with no user-accessible trim function.

Is MP8200DT-LF-P RoHS compliant?

Yes-suffix "-LF" explicitly denotes lead-free, RoHS-compliant packaging per EU Directive 2011/65/EU. The device meets JEDEC J-STD-020 moisture sensitivity level MSL3 and is compatible with standard reflow profiles for SOT23-3 packages.

Does MP8200DT-LF-P require an external capacitor for stability?

No-it is internally compensated and stable with no external capacitor, even under full 100µA–10mA load current variation. Adding capacitance may degrade transient response or cause oscillation; the datasheet explicitly states "stable with no external capacitor."

How does temperature affect MP8200DT-LF-P output accuracy?

Over –40°C to +85°C, output drift is bounded by 85 ppm/°C, resulting in ≤±8.5 mV total deviation from 1.000V nominal. This is verified across production lots and includes both initial tolerance and thermal coefficient contributions, making it suitable for industrial-grade instrumentation.

Why is MP8200 marked "Not Recommended for New Designs"?

MPS issued this notice because MP8201 replaces MP8200 with improved specs (0.5% accuracy, 0.3Ω Z_OUT, +125°C rating) and ongoing technical support. MP8200DT-LF-P remains available for legacy repair and continuity, but MP8201 is mandated for all new schematics requiring long-term supply assurance.
