Product details
Overview
The MAX8510EXK30+T from Maxim Integrated is a 3.0V fixed-output, ultra-low-noise, low-dropout linear regulator featuring a P-channel MOSFET pass element, 120mV dropout at 120mA load, 11μVRMS output noise (100Hz–100kHz), and 78dB PSRR at 1kHz - designed for powering sensitive analog circuitry in portable RF systems.
For engineers reviewing the MAX8510EXK30+T datasheet, MAX8510EXK30+T pinout, MAX8510EXK30+T application, or MAX8510EXK30+T equivalent, key selection criteria include guaranteed 120mA output with <40μA ground current, SC70-5 package compatibility, stability with 1μF ceramic output capacitance, and shutdown current below 1μA - critical for battery-powered audio, RF front-end, and precision sensor power rails.
Technical Context
The MAX8510EXK30+T employs an internal 1.225V bandgap reference and error amplifier to regulate its 3.0V output via feedback from an integrated resistor divider. Its P-channel MOSFET pass transistor (typ. RDS(ON) = 1Ω) eliminates base-drive current, enabling ultra-low quiescent current (40μA typical) across load and temperature.
It integrates a dedicated BP (bypass) pin for external 10nF capacitor connection to suppress broadband noise, achieving 11μVRMS output noise - a feature exclusive to the MAX8510 variant. Shutdown logic disables the reference, error amp, and gate driver, reducing supply current to <1μA while placing OUT in high-impedance state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% at +25°C; ±3% over full -40°C to +85°C range - ensures stable bias for ADC references and RF synthesizers. |
| Max Output Current | 120mA continuous - sufficient to power single-core microcontrollers, RF transceivers, or analog front-ends without thermal derating in SC70 package. |
| Dropout Voltage | 120mV at 120mA load (VOUT ≥ 3V) - enables operation down to 3.12V input, extending usable life of 3.6V Li-ion batteries. |
| Output Noise | 11μVRMS (100Hz–100kHz) with 10nF BP capacitor - meets stringent noise requirements for PLL VCO supplies and high-resolution audio DACs. |
| PSRR | 78dB at 1kHz, 54dB at 100kHz - rejects switching noise from adjacent DC/DC converters in mixed-signal PCBs. |
| Ground Current | 40μA typical at light load; 220μA max in dropout - minimizes standby power loss in always-on sensor nodes. |
| Shutdown Current | <1μA - enables deep-sleep modes in portable devices without compromising battery shelf life. |
Pinout & Package
MAX8510EXK30+T is housed in a RoHS-compliant, lead(Pb)-free 5-pin SC70 package (2.0mm × 1.25mm × 0.95mm height), optimized for space-constrained portable designs. The exposed pad is absent - thermal dissipation relies on GND pin conduction and board copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Unregulated input supply | Accepts 2V to 6V; must be bypassed with ≥1μF ceramic capacitor close to pin for stability and transient immunity. |
| 2 - GND | Ground reference and thermal path | Primary return for all internal circuits; connect to large PCB ground plane to limit θJA = 324°C/W and prevent thermal shutdown. |
| 3 - SHDN | Active-low shutdown control | Pull ≤0.4V to disable regulator; draws <0.01μA in shutdown; tie to IN for always-on operation. |
| 4 - BP | Noise bypass terminal | Connect 10nF capacitor to OUT to enable ultra-low-noise mode; shorted to OUT internally during shutdown. |
| 5 - OUT | Regulated 3.0V output | Delivers up to 120mA; requires ≥1μF ceramic capacitor to GND; high-impedance when SHDN is asserted. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 11μVRMS (100Hz–100kHz) enabled by dedicated BP pin and internal noise-bypass architecture - directly supports low-phase-noise RF signal chains. |
| P-channel MOSFET pass device | Eliminates base-drive current, enabling 40μA ground current independent of load - extends battery runtime in intermittent-duty applications. |
| Stability with minimal capacitance | Guaranteed stable with only 1μF ceramic output capacitor across full load and temperature - reduces BOM count and PCB area vs. traditional LDOs. |
| Integrated protection | Thermal shutdown (160°C trip, 10°C hysteresis) and current limiting (130–300mA range) - prevents damage during fault conditions without external components. |
| Low shutdown current | <1μA shutdown supply current - enables zero-power sleep states in IoT edge sensors and wearable health monitors. |
Applications
| RF Transceiver Power | High-Resolution Audio DAC Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A2030PDQNR | Lower 25μA quiescent current but higher 25μVRMS noise (10Hz–100kHz); no BP pin; requires ≥2.2μF output cap for stability. | Better suited for ultra-low-IQ always-on logic rails; not recommended for RF or high-precision analog where noise is critical. | Select TPS7A2030PDQNR only if quiescent current is primary constraint and noise <20μVRMS is acceptable. |
| MCP1700T-3002E/MB | Higher 200mV dropout at 250mA; 30μVRMS noise; SOT-23-5 package; no shutdown or BP functionality. | Cost-optimized for non-critical digital I/O rails; lacks RF-grade noise performance and enable control. | Choose MCP1700T-3002E/MB for cost-sensitive, non-noise-sensitive applications where SC70 size is not required. |
Compared with TPS7A2030PDQNR and MCP1700T-3002E/MB, the MAX8510EXK30+T uniquely delivers sub-12μVRMS noise with BP capacitor support and SC70 footprint - making it irreplaceable for noise-sensitive RF and precision analog subsystems despite slightly higher IQ.

FAQ
What is the output voltage tolerance of the MAX8510EXK30+T over temperature?
The MAX8510EXK30+T guarantees ±3% output voltage accuracy over the full −40°C to +85°C operating temperature range, with tighter ±1% tolerance specified at +25°C. This stability is achieved through a precision 1.225V bandgap reference and trimmed internal feedback resistors - ensuring reliable operation in automotive cabin and industrial handheld environments where ambient temperature swings occur.
Can the MAX8510EXK30+T operate stably with a 0.47μF ceramic output capacitor?
No - the MAX8510EXK30+T requires a minimum of 1μF ceramic output capacitance for guaranteed stability across all load conditions and temperatures, as validated in the datasheet's "Region of Stable COUT ESR vs. Load Current" plot. Using 0.47μF may cause oscillation or poor transient response, especially near dropout; X7R/X5R dielectrics are recommended to maintain capacitance over temperature.
Is the BP pin on the MAX8510EXK30+T mandatory for operation?
No - the BP pin is optional but essential for achieving the rated 11μVRMS output noise. Without the 10nF capacitor between BP and OUT, the MAX8510EXK30+T reverts to standard LDO performance (~230μVRMS, per MAX8511/MAX8512 specs). The BP pin is internally shorted to OUT during shutdown, so no external discharge path is needed.
What is the maximum allowable input voltage for the MAX8510EXK30+T?
The absolute maximum input voltage for the MAX8510EXK30+T is +7V, but the recommended operating range is 2V to 6V. Exceeding 6V risks exceeding the 0.247W power dissipation limit in the SC70 package at elevated ambient temperatures - particularly under high load or poor PCB thermal design - potentially triggering thermal shutdown or long-term reliability degradation.
Does the MAX8510EXK30+T support reverse-voltage protection?
No - the MAX8510EXK30+T does not integrate reverse-voltage protection. Applying reverse polarity to the IN or OUT pins (e.g., −0.3V below GND) violates absolute maximum ratings and may cause latch-up or permanent damage. External protection diodes or ideal diode controllers must be added if reverse-input or back-driving scenarios are possible in the target application.
