Product details
Overview
MAX8510EXK18+G65 from Maxim Integrated is a 1.8V 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 - designed for powering noise-sensitive analog circuitry in portable RF systems.
For engineers reviewing the MAX8510EXK18+G65 datasheet, MAX8510EXK18+G65 pinout, MAX8510EXK18+G65 application, or MAX8510EXK18+G65 equivalent, key selection criteria include guaranteed 120mA output current, 40µA ground current across load and temperature, SC70-5 package compatibility, and stable operation with only 1µF ceramic output capacitance.
Technical Context
The MAX8510EXK18+G65 implements a bandgap-referenced error amplifier driving a 1Ω (typ) P-channel MOSFET pass transistor, enabling low quiescent current (40µA typ) and minimal dropout without base-drive losses. Its BP pin supports external 10nF bypass capacitor to suppress noise via dedicated low-impedance path to the error amplifier's reference node.
Shutdown logic disables the voltage reference, error amplifier, and gate driver when SHDN is pulled low, reducing supply current to <1µA. Thermal shutdown activates at +160°C with 10°C hysteresis, and current limiting clamps output at 130–300mA depending on VOUT and load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8V ±3% over -40°C to +85°C; enables direct replacement of 1.8V logic rails without feedback resistor network. |
| Max Output Current | 120mA guaranteed minimum; sufficient to power multiple low-power RF ICs or ADCs from single LDO. |
| Dropout Voltage | 120mV at 120mA load; allows operation down to VIN = 1.92V, extending battery life in single-cell Li-ion or Li-poly systems. |
| Output Noise | 11µVRMS (100Hz–100kHz); meets stringent requirements for PLL VCO supplies and high-resolution SAR ADC references. |
| PSRR | 78dB at 1kHz, 54dB at 100kHz; suppresses switching noise from adjacent DC/DC converters feeding mixed-signal subsystems. |
| Ground Current | 40µA typical at no load; remains stable across input voltage (2V–6V) and temperature, minimizing standby power loss. |
| Shutdown Current | <1µA at VSHDN = 0V; supports deep-sleep modes in battery-powered IoT endpoints and wearables. |
Pinout & Package
MAX8510EXK18+G65 is housed in a 5-pin SC70-5 package (2.0mm × 1.25mm × 0.95mm height) with exposed pad not present - distinct from the TDFN variant. The GND pin serves dual electrical and thermal functions; PCB layout must use adequate copper area for heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Unregulated input supply | Accepts 2V to 6V input; requires 1µF ceramic capacitor to GND for stability and line-transient suppression. |
| 2 - GND | Ground reference and thermal path | Primary return for all internal circuits; must connect to large PCB ground plane to maintain thermal resistance <324°C/W. |
| 3 - SHDN | Active-low shutdown control | Pull ≤0.4V to disable regulator; internal pull-up ensures default ON if left open; compatible with 1.8V/3.3V GPIO. |
| 4 - BP | Noise bypass terminal | Connect 10nF capacitor to OUT to reduce output noise by >50%; shorted to OUT during shutdown. |
| 5 - OUT | Regulated 1.8V output | Delivers up to 120mA; stable with ≥1µF X7R/X5R ceramic capacitor; ESR <100mΩ required per stability curve. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 11µVRMS (100Hz–100kHz) achieved via dedicated BP pin and optimized bandgap core - critical for RF synthesizer VCO supplies. |
| P-channel MOSFET pass element | Eliminates base-drive current loss; maintains 40µA ground current even at full 120mA load and near-dropout conditions. |
| Stable with minimal capacitance | Guaranteed stability using only 1µF X7R/X5R ceramic output capacitor - reduces BOM count and board area vs. electrolytic-based LDOs. |
| Integrated protection | Thermal shutdown (160°C trip, 10°C hysteresis) and current limit (130–300mA range) prevent damage during fault conditions without external components. |
| Low-voltage shutdown interface | SHDN pin operates down to 0.4V logic low and up to 1.5V logic high - interoperable with sub-1.8V microcontrollers and PMICs. |
Applications
| Wireless Transceiver Power | High-Resolution ADC Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A20185PDBVR | 1.85V fixed output (±1.5%), 25µVRMS noise, 68dB PSRR @ 100kHz, 250mA output, SOT-23-5 package. | Higher output current but higher noise; lacks BP pin for noise optimization. | Select when higher load current is needed and 1.85V tolerance is acceptable; avoid for VCO supply where 11µVRMS is mandatory. |
| MCP1700T-1802E/MB | 1.8V fixed output (±2%), 30µVRMS noise, 60dB PSRR @ 100kHz, 250mA output, SOT-23-3 package (no SHDN). | No shutdown control; higher noise; smaller package but no BP pin or thermal protection. | Choose for cost-sensitive, non-critical analog rails where shutdown and ultra-low noise are not required. |
Compared with TPS7A20185PDBVR and MCP1700T-1802E/MB, the MAX8510EXK18+G65 delivers the lowest verified output noise (11µVRMS) and highest PSRR at 1kHz (78dB) in SC70-5, making it uniquely suitable for RF and precision analog supply roles where spectral purity is non-negotiable.

FAQ
What is the exact output voltage tolerance of MAX8510EXK18+G65 over temperature?
The MAX8510EXK18+G65 guarantees ±3% output voltage accuracy across the full operating temperature range of -40°C to +85°C, with typical deviation of ±1% at +25°C. This is confirmed in the Electrical Characteristics table under "Output Voltage Accuracy" with test conditions spanning 100µA to 80mA load current.
Can MAX8510EXK18+G65 operate stably with a 0.47µF output capacitor?
No - the MAX8510EXK18+G65 requires a minimum of 1µF ceramic output capacitance (X7R or X5R dielectric) for guaranteed stability across all loads and temperatures. Using 0.47µF violates the stability region defined in Figure toc20 and may cause oscillation, especially above 40mA load.
Does MAX8510EXK18+G65 include thermal shutdown protection?
Yes, the MAX8510EXK18+G65 integrates thermal shutdown that activates at +160°C junction temperature with 10°C hysteresis. When triggered, the pass transistor turns off completely, allowing the device to cool before automatically resuming regulation - a feature documented in the "Thermal-Overload Protection" section.
What is the maximum input voltage rating for MAX8510EXK18+G65?
The absolute maximum input voltage for MAX8510EXK18+G65 is +7V referenced to GND, but the recommended operating range is 2V to 6V. Operation above 6V risks exceeding safe power dissipation limits, especially at high ambient temperatures or heavy loads.
Is the BP pin on MAX8510EXK18+G65 required for basic operation?
No - the BP pin is optional and used exclusively to reduce output noise. The MAX8510EXK18+G65 regulates correctly without any BP capacitor, delivering 1.8V at up to 120mA. However, omitting the 10nF BP-to-OUT capacitor increases RMS noise from 11µV to ~230µV, as specified in the Electrical Characteristics table.
