Product details
Overview
The MAX8510EXK27+G65 from Maxim Integrated is a 2.7V 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 up to 120mA continuous output current with only 40µA ground current and operates from a 2V–6V input, targeting noise-sensitive analog rails in portable RF and precision signal-chain applications.
For engineers reviewing the MAX8510EXK27+G65 datasheet, MAX8510EXK27+G65 pinout, MAX8510EXK27+G65 application, or MAX8510EXK27+G65 equivalent, key selection criteria include its SC70-5 package footprint, BP-capacitor–enabled ultra-low-noise performance, guaranteed 120mA output capability, and shutdown current below 1µA - all critical for battery-powered, space-constrained designs requiring stable low-noise biasing.
Technical Context
The MAX8510EXK27+G65 implements a bandgap-referenced error amplifier driving a 1Ω (typ) P-channel MOSFET pass transistor, enabling low dropout and minimal quiescent current across load and temperature. Its BP pin connects to an external 10nF capacitor to shunt high-frequency noise from the reference node, directly enabling the 11µVRMS noise specification.
Shutdown control is active-low on the SHDN pin, disabling the reference, error amplifier, and gate driver to reduce supply current to <1µA; the device enters high-impedance output state. Thermal protection activates at +160°C junction temperature with 10°C hysteresis, and overcurrent limiting is set between 130mA (min) and 300mA (max).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7V ±3% over -40°C to +85°C; enables direct replacement of 2.7V logic or analog supply rails without feedback network design. |
| Dropout Voltage | 120mV at 120mA load; allows operation down to VIN = 2.82V, extending usable battery life in single-cell Li-ion or alkaline systems. |
| Output Noise | 11µVRMS (100Hz–100kHz); meets stringent noise requirements for RF synthesizers, ADC/DAC references, and low-phase-noise clock buffers. |
| PSRR | 78dB at 1kHz, 54dB at 100kHz; suppresses switching regulator ripple and digital supply coupling into sensitive analog circuitry. |
| Ground Current | 40µA typical at light load; minimizes standby power loss in always-on subsystems such as real-time clocks or sensor wake-up circuits. |
| Shutdown Current | <1µA; ensures negligible battery drain during system sleep modes without requiring external disconnect switches. |
| Stability | Guaranteed stable with ≥1µF ceramic output capacitor (X7R/X5R); eliminates need for tantalum or electrolytic capacitors and simplifies BOM. |
Pinout & Package
MAX8510EXK27+G65 is housed in a RoHS-compliant, lead-free 5-pin SC70 package (2.0mm × 1.25mm × 0.95mm), optimized for high-density portable PCB layouts. The exposed pad is absent in SC70; thermal dissipation relies on PCB copper area connected to GND via standard land pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Unregulated input supply | Accepts 2V–6V input; requires ≥1µF ceramic decoupling close to pin to ensure PSRR and transient response. |
| 2 - GND | Ground reference and thermal path | Primary return for all internal circuits; must connect to large PCB ground plane to maintain thermal performance and noise immunity. |
| 3 - SHDN | Active-low shutdown control | Pull ≤0.4V to disable regulator; floating or tied to IN enables operation; input bias current <0.1µA enables direct GPIO control. |
| 4 - BP | Noise bypass terminal | Connects 10nF capacitor to OUT to reduce reference noise; shorted to OUT internally during shutdown; leakage <10nA preserves capacitor charge. |
| 5 - OUT | Regulated 2.7V output | Delivers up to 120mA; requires ≥1µF ceramic capacitor to GND; output impedance remains low across full load and frequency range. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output voltage noise | 11µVRMS (100Hz–100kHz) enabled by BP-capacitor–assisted bandgap noise filtering - critical for powering VCOs and PLLs. |
| High PSRR at audio and switching frequencies | 78dB at 1kHz and 54dB at 100kHz - suppresses noise from DC/DC converters and digital ICs sharing the same input rail. |
| Low dropout with P-MOSFET architecture | 120mV at 120mA - enables efficient regulation from partially discharged batteries without sacrificing output accuracy. |
| Minimal external components | Only requires IN and OUT 1µF ceramic capacitors plus optional 10nF BP capacitor - reduces bill-of-materials and board area vs. traditional LDOs. |
| Robust protection suite | Integrated thermal shutdown (+160°C trip, 10°C hysteresis) and current limiting (130–300mA range) - eliminates need for external fault management circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS79527DRVR | 2.7V fixed, 250mA output, 30µVRMS noise, 65dB PSRR @ 100kHz, 6-pin WSON package | Higher output current but higher noise; lacks BP pin for noise optimization | Select when >120mA load or smaller WSON footprint is required; avoid when sub-15µV noise is mandatory. |
| MCP1703T-2702E/MB | 2.7V fixed, 250mA output, 40µVRMS noise, 55dB PSRR @ 100kHz, SOT-23-5 package | Higher noise and lower PSRR; no BP pin; wider dropout (330mV @ 250mA) | Choose for cost-sensitive, non-noise-critical 2.7V rails; not suitable for RF or high-resolution data acquisition. |
Compared with TPS79527DRVR and MCP1703T-2702E/MB, the MAX8510EXK27+G65 uniquely delivers 11µVRMS noise and 78dB PSRR at 1kHz in a 5-pin SC70, making it the only option among the three qualified for ultra-low-noise RF and precision analog biasing where noise spectral density directly impacts system SNR.

FAQ
What is the output voltage tolerance of the MAX8510EXK27+G65 over temperature and load?
The MAX8510EXK27+G65 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 +25°C and 1mA load, the tolerance tightens to ±1%. This specification ensures reliable operation in battery-powered devices subject to wide ambient temperature swings and dynamic load profiles, without requiring post-manufacturing calibration.
Can the MAX8510EXK27+G65 operate with ceramic output capacitors smaller than 1µF?
No - the MAX8510EXK27+G65 is specified and guaranteed stable only with ≥1µF ceramic output capacitance (X7R or X5R dielectric). Using smaller values risks instability, excessive ringing during load transients, and degraded PSRR. The 1µF minimum is a hard design requirement validated across process, voltage, and temperature corners per the datasheet's "Region of Stable COUT ESR" graph.
How does the BP pin function in the MAX8510EXK27+G65, and what capacitor value is recommended?
The BP pin in the MAX8510EXK27+G65 connects to an external 10nF capacitor tied to the OUT pin, forming a low-impedance shunt path for high-frequency noise on the internal bandgap reference. This configuration directly enables the 11µVRMS noise specification. Capacitor values below 1nF or above 100nF degrade noise performance; 10nF is the optimal, validated value per the "Output Noise vs. BP Capacitance" curve in the datasheet.
What is the maximum allowable input voltage for the MAX8510EXK27+G65, and what happens if exceeded?
The absolute maximum input voltage for the MAX8510EXK27+G65 is +7V relative to GND. Exceeding this rating - even momentarily - may cause permanent damage to the internal P-channel MOSFET or bandgap circuitry. Operation above the recommended 2V–6V range degrades PSRR, increases ground current, and voids parametric guarantees; sustained overvoltage triggers irreversible junction failure.
Does the MAX8510EXK27+G65 require a minimum load current to maintain regulation?
No - the MAX8510EXK27+G65 maintains regulation and specified accuracy down to zero load current (0mA). Its ground current remains at 40µA typical under no-load conditions, and output voltage deviation stays within ±3% across the full 0–120mA load range. This zero-load capability is essential for intermittent-duty applications like sensor wake-up circuits and standby power domains.
