Product details
Overview
MAX8510EXK28 from Maxim Integrated is a 2.8V 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. It delivers stable 2.8V power to noise-sensitive RF and analog circuitry in portable wireless devices.
For engineers reviewing the MAX8510EXK28 datasheet, MAX8510EXK28 pinout, MAX8510EXK28 application, or MAX8510EXK28 equivalent, key selection criteria include its 2.8V preset output, SC70-5 package footprint, sub-1µA shutdown current, 40µA ground current under light load, and compatibility with 1µF ceramic output capacitance for stability across all loads.
Technical Context
The MAX8510EXK28 employs an innovative bandgap reference core with integrated noise-bypass architecture centered on the BP pin, enabling ultra-low RMS noise performance without requiring external LDO post-filtering. Its error amplifier compares a 1.225V internal reference against the regulated output via an internal feedback divider.
It uses a 1Ω (typ) P-channel MOSFET pass transistor-eliminating base-drive current and minimizing quiescent consumption-enabling 40µA ground current at no load and only 220µA in dropout. Shutdown logic disables the reference, error amp, and gate driver, reducing supply current to <1µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±3% over -40°C to +85°C; enables direct replacement of 2.8V logic rails without external resistors. |
| Max Output Current | 120mA guaranteed; supports moderate-power RF ICs, ADCs, and PLLs without thermal derating in SC70 package. |
| Dropout Voltage | 120mV at 120mA load; allows operation down to VIN = 2.92V, extending usable battery life in single-cell Li-ion systems. |
| Output Noise | 11µVRMS (100Hz–100kHz); meets stringent spectral purity requirements for VCO biasing and high-resolution sensor signal chains. |
| PSRR | 78dB at 1kHz, 54dB at 100kHz; suppresses switching noise from DC/DC converters feeding intermediate supply rails. |
| Ground Current | 40µA typical at light load; minimizes standby power in always-on subsystems such as Bluetooth LE receivers. |
| Shutdown Current | <1µA; enables deep-sleep modes in portable equipment with negligible battery drain over weeks. |
Pinout & Package
MAX8510EXK28 is housed in a 5-pin SC70-5 package (2.0mm × 1.25mm × 0.95mm, 0.65mm pitch), optimized for space-constrained PCB layouts. The exposed pad variant is not used in this part number; thermal dissipation relies on GND pin conduction through standard copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Unregulated input supply | Accepts 2V to 6V input; requires ≥1µF ceramic capacitor to GND for EMI filtering and transient response. |
| 2 - GND | Power and signal ground reference | Dual-function pin: provides return path and conducts heat; must connect to large copper area for thermal management. |
| 3 - SHDN | Active-low shutdown control | Pulled high to IN for normal operation; driven low to disable regulator and reduce IQ to <1µA. |
| 4 - BP | Noise bypass terminal | Connects 10nF capacitor to OUT to shunt high-frequency noise from bandgap reference; shorted to OUT during shutdown. |
| 5 - OUT | Regulated 2.8V output | Stable with ≥1µF ceramic capacitor to GND; supports full 120mA load without oscillation across temperature and voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 11µVRMS (100Hz–100kHz) enabled by dedicated BP pin and internal noise-bypass architecture-critical for RF synthesizer VCO supplies. |
| High PSRR at audio frequencies | 78dB rejection at 1kHz ensures clean power delivery to sensitive analog blocks adjacent to noisy digital processors. |
| Stability with minimal capacitance | Guaranteed stable with only 1µF ceramic output capacitor-reduces BOM count and board area vs. traditional LDOs requiring ≥10µF. |
| P-channel MOSFET pass element | Eliminates base-drive current loss, enabling 40µA ground current at no load and consistent dropout behavior across temperature. |
| Integrated protection | Thermal shutdown (160°C trip, 10°C hysteresis) and current limiting (130–300mA range) prevent damage during fault conditions without external components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B282MR-G | 2.8V fixed, 150mA, 250mV dropout at 150mA, 45µVRMS noise, SOT-25 package | Higher dropout and noise limit use in RF-sensitive designs; lacks BP pin for noise optimization | Lower-cost option where 250mV dropout and 45µVRMS noise are acceptable, e.g., non-RF microcontroller peripherals |
| Analog Devices ADP125ARHZ-2.8-R7 | 2.8V fixed, 500mA, 135mV dropout at 500mA, 30µVRMS noise, 6-lead SOT-23 | Higher current capability but larger footprint and higher ground current (120µA typ); no BP pin | Suitable when system requires >120mA or needs margin for future expansion, but trades off noise performance and board area |
Compared with the Torex XC6210B282MR-G and ADP125ARHZ-2.8-R7, the MAX8510EXK28 uniquely combines SC70-5 size, 11µVRMS noise, and 120mV dropout-making it the only choice for miniaturized, RF-critical 2.8V rails where spectral purity and battery efficiency are co-prioritized.

FAQ
What is the output voltage tolerance of the MAX8510EXK28 over temperature and load?
The MAX8510EXK28 guarantees ±3% output voltage accuracy over the full -40°C to +85°C operating temperature range and for output currents from 100µA to 80mA. At room temperature and 1mA load, the tolerance tightens to ±1%. This specification ensures reliable logic-level compatibility with 2.8V I/O standards across environmental stress conditions without requiring external trimming.
Can the MAX8510EXK28 operate stably with a 0.47µF ceramic output capacitor?
No-the MAX8510EXK28 is specified and tested for stability only with ≥1µF ceramic output capacitance. Using 0.47µF violates the minimum COUT requirement and risks oscillation under certain load and temperature conditions, as confirmed by the "Region of Stable COUT ESR vs. Load Current" graph in the datasheet. Always use 1µF or greater X7R/X5R dielectric capacitors.
Is the BP pin required for basic operation of the MAX8510EXK28?
The BP pin is not required for basic regulation but is mandatory to achieve the specified 11µVRMS output noise. Leaving BP unconnected degrades noise performance to ~230µVRMS (per MAX8511/MAX8512 spec). For MAX8510EXK28, a 10nF capacitor must be placed between BP and OUT to activate the internal noise-bypass circuit and meet datasheet noise targets.
Does the MAX8510EXK28 support reverse polarity protection on the IN pin?
No-the MAX8510EXK28 has no built-in reverse polarity protection. Absolute maximum rating for IN to GND is -0.3V; applying reverse voltage will cause permanent damage. External protection (e.g., series Schottky diode or ideal diode controller) must be added if reverse input is possible in the application.
What is the thermal resistance (θJA) of the MAX8510EXK28 in its SC70-5 package?
The MAX8510EXK28 in SC70-5 package has a junction-to-ambient thermal resistance (θJA) of 324°C/W, measured on a standard JEDEC 2-layer board. This value assumes minimal copper area; actual θJA improves significantly with increased GND pad copper and thermal vias-designers should follow Maxim's layout guidelines to maintain junction temperature below 150°C at 120mA load.
