Product details
Overview
The MAX8510EXK27 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, 11µVRMS output noise (100Hz–100kHz), and 78dB PSRR at 1kHz. It delivers stable 2.7V power to noise-sensitive analog circuitry in portable RF and precision signal-chain applications.
For engineers reviewing the MAX8510EXK27 datasheet, MAX8510EXK27 pinout, MAX8510EXK27 application, or MAX8510EXK27 equivalent, key selection criteria include its 2.7V preset output, SC70-5 package footprint, sub-1µA shutdown current, 40µA ground current under light load, and guaranteed stability with only 1µF ceramic output capacitance.
Technical Context
The MAX8510EXK27 uses an internal 1.225V bandgap reference and error amplifier to regulate output against load and line variations. Its P-channel MOSFET pass transistor enables low dropout and eliminates base-drive current, achieving 40µA quiescent ground current across load and temperature.
It integrates a dedicated BP (bypass) pin for external 10nF capacitor connection to reduce output voltage noise to 11µVRMS; shutdown control via SHDN pin disables reference, error amp, and pass transistor, reducing supply current to <1µA while placing OUT in high-impedance state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7V ±3% over -40°C to +85°C, enabling direct replacement of 2.7V logic or analog rails without feedback resistors. |
| Dropout Voltage | 120mV at 120mA load, allowing operation down to VIN = 2.82V - critical for extending battery life in single-cell Li-ion or alkaline systems. |
| Output Noise | 11µVRMS (100Hz–100kHz) with 10nF BP capacitor, meeting stringent noise requirements for RF receivers, ADC references, and PLL VCO supplies. |
| PSRR | 78dB at 1kHz, 54dB at 100kHz - suppresses switching noise from upstream DC/DC converters feeding sensitive analog stages. |
| Ground Current | 40µA typical at no load, rising to 220µA in dropout - minimizes standby power loss in always-on sensor or communication modules. |
| Shutdown Current | <1µA at VSHDN = 0V - supports deep-sleep modes in battery-powered IoT endpoints without compromising wake-up latency. |
| Stability | Guaranteed stable with ≥1µF ceramic output capacitor (X7R/X5R), eliminating need for tantalum or large bulk capacitors and reducing BOM cost and board area. |
Pinout & Package
MAX8510EXK27 is housed in a 5-pin SC70-5 package (2.0mm × 1.25mm × 0.95mm height) with exposed pad not present - GND connection is made solely through Pin 2. The package supports reflow soldering and meets RoHS compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Unregulated input supply | Accepts 2V to 6V input; requires 1µF ceramic decoupling close to pin for optimal transient response and PSRR. |
| 2 - GND | Power and signal ground reference | Serves as primary thermal and electrical return path; must connect to solid ground plane to maintain 40µA quiescent current and thermal stability. |
| 3 - SHDN | Active-low enable/disable control | Pull ≤0.4V to disable regulator; internal pull-up ensures default ON if left open; compatible with 1.8V/3.3V logic. |
| 4 - BP | Noise bypass terminal | Connects to OUT via 10nF capacitor to reduce output noise by >50% - essential for achieving 11µVRMS spec; shorted to OUT during shutdown. |
| 5 - OUT | Regulated 2.7V 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) with BP capacitor - enables clean power for RF front-ends and high-resolution ADCs without additional LDO staging. |
| P-channel MOSFET pass element | Eliminates base-drive current and saturation losses - maintains 40µA ground current even at full 120mA load, unlike PNP-based regulators. |
| Single-capacitor stability | Stable with only 1µF ceramic output capacitor (X7R/X5R) - reduces component count, PCB area, and cost versus traditional LDOs requiring ≥10µF. |
| Low dropout architecture | 120mV dropout at 120mA - extends usable battery voltage range by ~150mV compared to standard NPN LDOs, delaying system brownout. |
| Integrated protection | Thermal shutdown (160°C trip, 10°C hysteresis) and current limit (130–300mA) - prevents damage during overload or ambient temperature excursions without external circuitry. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS79527DRVR | 2.7V fixed, 150mA, 30µVRMS noise, 60dB PSRR @ 100kHz, SOT-23-5 package | Higher noise and lower PSRR limit use in RF or high-precision ADC applications; larger package increases board area. | Select when cost is prioritized over noise performance and SC70 footprint is not required. |
| MCP1703T-2702E/MB | 2.7V fixed, 250mA, 45µVRMS noise, 50dB PSRR @ 100kHz, SOT-23-5 package | Significantly higher output noise degrades SNR in sensitive analog stages; lacks BP pin for noise optimization. | Choose only for non-critical digital I/O or logic supply where noise immunity is not specified. |
Compared with TPS79527DRVR and MCP1703T-2702E/MB, the MAX8510EXK27 uniquely delivers 11µVRMS noise and 78dB PSRR in the smallest SC70-5 footprint - making it the sole option for space-constrained, noise-critical 2.7V rails where performance cannot be compromised.

FAQ
What is the exact output voltage tolerance of the MAX8510EXK27 over temperature and load?
The MAX8510EXK27 guarantees ±3% output voltage accuracy over the full operating range of -40°C to +85°C and for load currents from 100µA to 80mA. At room temperature and 1mA load, typical deviation is ±1%. This tolerance ensures reliable operation of 2.7V-tolerant logic and analog components without external trimming.
Can the MAX8510EXK27 operate with input voltages below 2.7V?
No - the MAX8510EXK27 requires a minimum input voltage of 2V, but to maintain regulation at its 2.7V output, VIN must exceed VOUT by at least the dropout voltage. At 120mA load, dropout is 120mV, so VIN must be ≥2.82V. Below this, output collapses linearly; operation below 2.7V input is only possible in dropout mode with reduced output voltage.
Is a bypass capacitor mandatory on the BP pin of the MAX8510EXK27?
Yes - the BP pin is integral to achieving the 11µVRMS noise specification. A 10nF capacitor between BP and OUT is required to activate the internal noise-bypass circuitry. Omitting it results in ~230µVRMS noise (per datasheet Table, MAX8511/MAX8512 column), degrading performance by over 20× in noise-sensitive applications.
Does the MAX8510EXK27 require an external feedback resistor network?
No - the MAX8510EXK27 is a factory-preset 2.7V regulator with internal feedback divider. Unlike the adjustable MAX8512, it has no FB pin and does not support external voltage programming. Its pinout (IN, GND, SHDN, BP, OUT) confirms fixed-output configuration with no feedback terminals.
What is the thermal performance difference between the SC70 and TDFN packages for the MAX8510?
The SC70-5 package has θJA = 324°C/W, while the TDFN-EP (2mm × 2mm) achieves θJA = 83.9°C/W - a 3.9× improvement. For the same 120mA load at VIN = 5V, the SC70 version dissipates 276mW and rises ~90°C above ambient, whereas the TDFN version rises only ~23°C. The exposed pad in TDFN is essential for thermal relief; SC70 lacks this feature.
