Product details
Overview
The MAX8510ETA28+ from Maxim Integrated is a preset 2.8V, 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 - optimized for powering noise-sensitive analog circuitry in portable RF and precision signal-chain applications.
For engineers reviewing the MAX8510ETA28+ datasheet, MAX8510ETA28+ pinout, MAX8510ETA28+ application, or MAX8510ETA28+ equivalent, key selection criteria include guaranteed 120mA output current, stable operation with only 1µF ceramic output capacitance, sub-1µA shutdown current, and TDFN-EP (2mm × 2mm) thermal performance enabling high-density battery-powered designs.
Technical Context
The MAX8510ETA28+ employs an innovative bandgap reference core with integrated noise-bypass architecture centered on the BP pin, where a 10nF capacitor to OUT reduces output voltage noise to 11µVRMS. Its P-channel MOSFET pass transistor delivers 1Ω typical RDS(ON), enabling low ground current (40µA typical) across load and temperature.
Regulation relies on internal feedback with fixed 2.8V output set by laser-trimmed resistors; SHDN controls enable/disable logic that disables the reference, error amplifier, and gate driver, reducing supply current to <1µA. Thermal shutdown activates at +160°C with 10°C hysteresis, and current limiting is active up to 300mA (min 130mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±3% over -40°C to +85°C - ensures stable biasing for RF front-ends and ADC references without external resistor network. |
| Max Output Current | 120mA guaranteed - supports moderate-power analog subsystems such as Bluetooth transceivers or camera sensor ICs. |
| Dropout Voltage | 120mV at 120mA load - extends usable battery life down to VIN = 2.92V for 2.8V rail, critical in single-cell Li-ion systems. |
| Output Noise | 11µVRMS (100Hz–100kHz) with 10nF BP capacitor - meets stringent noise requirements for PLL VCO supplies and audio DACs. |
| PSRR | 78dB at 1kHz, 54dB at 100kHz - suppresses switching noise from adjacent DC/DC converters feeding sensitive analog blocks. |
| Ground Current | 40µA typical at light load, 220µA in dropout - minimizes quiescent power loss in always-on subsystems like real-time clocks or sensor interfaces. |
| Shutdown Current | <1µA - enables deep-sleep modes in portable devices without compromising system-level power budget. |
Pinout & Package
Package: 8-pin TDFN-EP (2mm × 2mm × 0.8mm) with exposed pad connected internally to GND - requires soldering EP to large PCB ground plane for optimal thermal dissipation (θJA = 83.9°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Unregulated input supply | Accepts 2V to 6V input; must be decoupled with ≥1µF ceramic capacitor close to pin for stability and line-transient immunity. |
| 2 (GND) | Ground reference and thermal path | Primary return path for load current and internal circuitry; EP connection enhances thermal conduction to PCB ground plane. |
| 3 (SHDN) | Active-low shutdown control | Pull ≤0.4V to disable regulator; logic-high ≥1.5V enables operation; input bias current <0.1µA minimizes leakage impact. |
| 4 (BP) | Noise bypass terminal | Connect 10nF capacitor to OUT to reduce output noise to 11µVRMS; shorted to OUT during shutdown. |
| 5 (OUT) | Regulated 2.8V output | Delivers up to 120mA; requires ≥1µF ceramic capacitor to GND; ESR stability region defined per load current (see datasheet Fig. toc20). |
| 6, 7, 8 (N.C.) | No connection | Not internally bonded; no electrical function - must remain unconnected per design. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 11µVRMS (100Hz–100kHz) with 10nF BP capacitor - enables clean power for VCOs, ADCs, and RF synthesizers without additional filtering. |
| High PSRR at audio frequencies | 78dB at 1kHz - effectively rejects ripple from buck converters operating near audio bands, preserving signal integrity. |
| Stable with minimal capacitance | Guaranteed stability using only 1µF ceramic output capacitor - reduces BOM count and board area vs. regulators requiring ≥10µF tantalum. |
| P-channel MOSFET pass element | 1Ω typical RDS(ON) - eliminates base-drive current loss, enabling 40µA ground current independent of load, unlike PNP-based LDOs. |
| Robust protection suite | Thermal shutdown (+160°C, 10°C hysteresis) and current limit (130–300mA) - allows indefinite short-circuit survival and safe operation under transient overload. |

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 |
|---|---|---|---|
| Torex XC6210B282MR-G | 2.8V fixed, 100mA max, 25µVRMS noise, requires 4.7µF output cap for stability | Limited to lower current; higher noise degrades RF/analog performance | Select when cost sensitivity outweighs noise and current requirements; verify stability with larger COUT. |
| Analog Devices ADP125ARHZ-2.8-R7 | 2.8V fixed, 500mA max, 40µVRMS noise, 170mV dropout at 500mA | Higher current and dropout; noise 3.6× worse than MAX8510ETA28+ | Choose for higher-load applications where ultra-low noise is secondary; not suitable for VCO or precision ADC use cases. |
Compared with the XC6210B282MR-G and ADP125ARHZ-2.8-R7, the MAX8510ETA28+ uniquely balances ultra-low noise (11µVRMS), 120mA capability, and 1µF ceramic stability - making it irreplaceable in space-constrained, noise-critical RF and high-fidelity audio subsystems.

FAQ
What is the exact output voltage tolerance of the MAX8510ETA28+ over temperature?
The MAX8510ETA28+ guarantees ±3% output voltage accuracy over the full -40°C to +85°C operating temperature range, with typical deviation within ±0.4% at +25°C. This specification is verified across load currents from 100µA to 80mA and is laser-trimmed at wafer test - ensuring reliable 2.8V regulation for precision analog loads without external calibration. The MAX8510ETA28+ maintains this accuracy even under varying line and load conditions due to its high PSRR and low ground current drift.
Can the MAX8510ETA28+ operate stably with a 1µF X5R ceramic capacitor on the output?
Yes, the MAX8510ETA28+ is fully characterized and guaranteed stable with a 1µF X5R ceramic capacitor on the output across all load conditions and temperatures. Unlike many LDOs requiring larger or specialized capacitors, the MAX8510ETA28+'s internal compensation and P-channel architecture eliminate ESR dependency - enabling robust performance with low-cost, small-footprint X5R dielectrics. This is confirmed in the "Region of Stable COUT ESR vs. Load Current" plot (Figure toc20) in the official datasheet.
What is the purpose of the BP pin on the MAX8510ETA28+, and what capacitor value is recommended?
The BP (Bypass) pin on the MAX8510ETA28+ connects to an internal noise-reduction circuit that dramatically lowers output voltage noise. A 10nF capacitor between BP and OUT reduces RMS noise to 11µV (100Hz–100kHz); values from 1nF to 100nF are acceptable, but 10nF is optimal. The BP pin is shorted to OUT during shutdown, and its leakage current is <10nA - ensuring minimal impact on capacitor selection. This feature is exclusive to the MAX8510 variant and not present on MAX8511/MAX8512.
Does the MAX8510ETA28+ require an input capacitor, and if so, what type and value?
Yes, the MAX8510ETA28+ requires a minimum 1µF ceramic input capacitor (X5R or X7R) placed as close as possible to the IN and GND pins. This capacitor improves line-transient response, reduces input ripple propagation, and ensures stability under fast-varying source impedances - especially critical when powered from switchers or long PCB traces. Larger values (e.g., 4.7µF) further enhance noise rejection but are not required for basic functionality or stability per the datasheet.
How does thermal performance differ between the SC70 and TDFN packages of the MAX8510 series?
The MAX8510ETA28+ uses the 8-pin TDFN-EP package (2mm × 2mm), which provides significantly better thermal performance than the SC70 option: θJA = 83.9°C/W vs. 324°C/W for SC70. This 3.9× improvement enables higher continuous power dissipation - up to 0.953W at +70°C ambient - making the TDFN version essential for sustained 120mA operation in compact enclosures. The exposed pad (EP) must be soldered to a solid ground plane to realize this benefit; the SC70 lacks thermal enhancement and is limited to lower-current or pulsed-duty applications.
