Product details
Overview
MAX8510EXK29-T from Maxim Integrated is a 2.85V 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 120mA output with only 40µA ground current and operates from 2V to 6V input, targeting noise-sensitive analog and RF power rails in portable electronics.
For engineers reviewing the MAX8510EXK29-T datasheet, MAX8510EXK29-T pinout, MAX8510EXK29-T application, or MAX8510EXK29-T equivalent, key selection criteria include its 2.85V preset output, SC70-5 package footprint, BP-capacitor–enabled ultra-low-noise performance, and guaranteed 120mA output with thermal/overcurrent protection - critical for battery-powered signal-chain and wireless subsystems.
Technical Context
The MAX8510EXK29-T uses an internal 1.225V bandgap reference and error amplifier to regulate output against load and line variations, with feedback provided by an internal resistor divider. Its P-channel MOSFET pass transistor (typ. RDS(ON) = 1Ω) eliminates base-drive current, enabling ultra-low quiescent current across load conditions.
Dropout behavior is defined by RDS(ON) × ILOAD, yielding 120mV at 120mA; noise reduction relies on a dedicated BP pin accepting a 10nF capacitor to shunt high-frequency reference noise, achieving 11µVRMS output noise. 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 2.85V ±3% over -40°C to +85°C; enables direct replacement of 2.85V rails without external resistors. |
| Max Output Current | 120mA continuous; supports moderate-power analog ICs (e.g., ADCs, op-amps) and RF front-end biasing. |
| Dropout Voltage | 120mV at 120mA load; allows operation down to VIN = 2.97V, extending usable battery life in single-cell Li-ion systems. |
| Output Noise | 11µVRMS (100Hz–100kHz); meets stringent requirements for PLL/VCO power, audio DACs, and precision sensor interfaces. |
| PSRR | 78dB at 1kHz, 54dB at 100kHz; suppresses switching noise from upstream DC/DC converters feeding sensitive analog stages. |
| Ground Current | 40µA typical at light load; minimizes standby power loss in always-on subsystems like Bluetooth radios or real-time clocks. |
| Shutdown Current | <1µA; enables deep-sleep modes in portable devices without compromising wake-up latency or rail integrity. |
Pinout & Package
MAX8510EXK29-T is housed in a RoHS-compliant 5-pin SC70-5 package (2.0mm × 1.25mm × 0.9mm), with exposed pad omitted (non-EP variant). The package supports reflow soldering and requires no thermal pad connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Unregulated input supply | Accepts 2V–6V input; must be bypassed with ≥1µF ceramic capacitor close to pin for stability and noise rejection. |
| 2 - GND | Ground reference and thermal path | Serves as primary return for all internal circuits; connects to PCB ground plane to manage self-heating under 120mA load. |
| 3 - SHDN | Active-low shutdown control | Pull ≤0.4V to disable regulator; floats or ties to IN for normal operation; input bias current <0.1µA minimizes leakage impact. |
| 4 - BP | Noise bypass terminal | Connects 10nF capacitor to OUT to reduce reference noise; shorted to OUT during shutdown; leakage <10nA preserves capacitor charge. |
| 5 - OUT | Regulated 2.85V output | Delivers up to 120mA; requires ≥1µF ceramic output capacitor; ESR stability region defined per load current (see datasheet Fig. toc20). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 11µVRMS (100Hz–100kHz) enabled by BP pin and internal noise-bypass architecture - critical for VCO/PLL power integrity. |
| High PSRR at audio frequencies | 78dB at 1kHz ensures effective suppression of ripple from buck converter switching edges near 1kHz harmonics. |
| Stable with minimal capacitance | Guaranteed stability with only 1µF ceramic output capacitor across full load range - reduces BOM count and board area. |
| P-channel MOSFET pass device | Eliminates base-drive current, enabling 40µA ground current at light loads and consistent dropout vs. temperature. |
| Integrated protection | Thermal shutdown (160°C trip, 10°C hysteresis) and current limiting (130–300mA range) prevent damage during fault conditions. |

FAQ
What is the output voltage tolerance of the MAX8510EXK29-T over temperature and load?
The MAX8510EXK29-T guarantees ±3% output voltage accuracy across −40°C to +85°C and for load currents from 100µA to 80mA. At 25°C and 1mA load, tolerance tightens to ±1%. This ensures reliable operation for 2.85V-dependent analog circuits without external trimming.
Can the MAX8510EXK29-T operate stably with a 1µF ceramic output capacitor?
Yes - the MAX8510EXK29-T is explicitly characterized and guaranteed stable with a single 1µF X7R/X5R ceramic capacitor on the output across all load conditions. Larger values improve transient response and PSRR, but 1µF meets minimum stability requirements per datasheet Figure toc20.
What is the purpose of the BP pin on the MAX8510EXK29-T, and what capacitor value is recommended?
The BP (Bypass) pin on the MAX8510EXK29-T connects to an external 10nF capacitor between BP and OUT to shunt high-frequency noise from the internal bandgap reference. This configuration achieves the specified 11µVRMS output noise. Capacitors outside 1nF–100nF are not recommended per datasheet guidance.
How does the MAX8510EXK29-T behave during shutdown, and what is its shutdown current?
When SHDN is pulled low (<0.4V), the MAX8510EXK29-T disables its voltage reference, error amplifier, and pass transistor gate driver, placing OUT in high-impedance state. Shutdown supply current drops to <1µA at +25°C and <0.05µA at +85°C - enabling ultra-low-power sleep modes in battery systems.
Is the MAX8510EXK29-T compatible with standard SC70-5 footprints and reflow profiles?
Yes - the MAX8510EXK29-T uses a standard 5-pin SC70-5 package (outline 21-0076) with lead(Pb)-free/RoHS-compliant terminations. It supports JEDEC J-STD-020C reflow profiles, including peak temperatures up to +260°C, and requires no exposed pad thermal connection.
