Product details
Overview
MAX8510EUA45 from Maxim Integrated is a 4.5V fixed-output, ultra-low-noise, low-dropout linear regulator featuring 11µVRMS output noise (100Hz–100kHz), 78dB PSRR at 1kHz, and 120mV dropout at 120mA load. It uses a P-channel MOSFET pass device, delivers guaranteed 120mA output, and targets noise-sensitive analog rails in portable RF and precision signal-chain applications.
For engineers reviewing the MAX8510EUA45 datasheet, MAX8510EUA45 pinout, MAX8510EUA45 application, or MAX8510EUA45 equivalent, key selection criteria include its 4.5V preset output, SC70-5 package footprint, sub-1µA shutdown current, 40µA ground current under light load, and BP-capacitor–enabled ultra-low-noise performance - critical for cellular transceivers, Bluetooth audio, and high-fidelity portable power domains.
Technical Context
The MAX8510EUA45 implements a bandgap-referenced error amplifier driving a 1Ω (typ) P-channel MOSFET pass transistor, enabling low quiescent current and dropout independent of base-drive losses. Its BP pin connects to an internal noise-bypass circuit that shunts high-frequency reference noise to OUT via an external 10nF capacitor.
Shutdown logic disables the voltage reference, error amplifier, and gate driver when SHDN is pulled low, reducing supply current to <1µA. Thermal protection activates at +160°C with 10°C hysteresis, and current limiting holds output at 130–300mA during overload - ensuring robust operation in battery-powered edge devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 4.5V ±3% - ensures stable bias for 4.5V-tolerant RF front-ends and ADC references without external feedback. |
| Dropout Voltage | 120mV at 120mA - enables operation down to VIN = 4.62V, extending usable battery life in single-cell Li-ion or dual-cell alkaline systems. |
| Output Noise | 11µVRMS (100Hz–100kHz) - meets stringent SNR requirements for audio codecs and low-phase-noise VCO supplies. |
| PSRR | 78dB at 1kHz, 54dB at 100kHz - suppresses switching noise from adjacent DC/DC converters feeding mixed-signal SoCs. |
| Ground Current | 40µA (typ) at no load - minimizes standby power in always-on sensor nodes and wearable wake-up circuits. |
| Shutdown Current | <1µA - supports deep-sleep modes in Bluetooth LE peripherals and IoT endpoints with multi-year battery life. |
| Stability | Guaranteed with 1µF ceramic output capacitor - eliminates need for large tantalum or electrolytic caps, saving PCB area and cost. |
Pinout & Package
MAX8510EUA45 is housed in a 5-pin SC70 package (2.0mm × 1.25mm × 0.95mm height), with exposed pad not present - distinct from the TDFN variant. Pin 1 is IN; Pin 2 is GND; Pin 3 is SHDN; Pin 4 is BP; Pin 5 is OUT. All pins are surface-mount, RoHS-compliant, and rated for -40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Unregulated input supply | Accepts 2V–6V input; must be decoupled with ≥1µF ceramic cap close to pin to ensure PSRR and transient response. |
| GND (Pin 2) | Power and signal reference | Serves as return path for all internal currents and thermal conduction path; requires low-impedance PCB ground plane. |
| SHDN (Pin 3) | Active-low enable control | Pull ≤0.4V to disable regulator; connect to IN or logic high for always-on operation; input bias current <0.1µA. |
| BP (Pin 4) | Noise bypass terminal | Connects to internal bandgap noise filter; requires 10nF capacitor to OUT to achieve 11µVRMS noise performance. |
| OUT (Pin 5) | Regulated output | Delivers up to 120mA at 4.5V; requires ≥1µF ceramic capacitor to GND for stability; high-impedance in shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 11µVRMS (100Hz–100kHz) achieved via dedicated BP pin and internal noise-shunting architecture - directly improves ADC ENOB and RF receiver sensitivity. |
| High PSRR across frequency | 78dB at 1kHz and 54dB at 100kHz - enables clean analog supply in proximity to noisy digital or switching regulators without additional LC filtering. |
| P-channel MOSFET pass element | 1Ω (typ) RDS(ON) - eliminates base-drive current loss, sustaining 40µA ground current even at full 120mA load and extending battery runtime. |
| Minimal external components | Only IN and OUT 1µF ceramics required - reduces BOM count, board space, and design validation effort versus traditional LDOs needing multiple capacitors. |
| Robust protection suite | Integrated overcurrent limit (130–300mA), thermal shutdown (+160°C), and 10°C hysteresis - allows safe operation in unattended portable equipment without external supervision. |
Applications
| Cellular Transceiver Power | Bluetooth Audio Codec Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B452MR-G | 4.5V fixed, 150mA, 25µVRMS noise, no BP pin, 250mV dropout at 150mA | Lacks BP-based noise reduction; higher noise limits use in VCO or high-SNR audio paths | Select when board space is constrained and noise <20µVRMS is acceptable; verify stability with 1µF X7R ceramic. |
| Analog Devices ADP125ARHZ-4.5-R7 | 4.5V fixed, 500mA, 40µVRMS noise, 200mV dropout at 500mA, no BP pin | Higher current but significantly higher output noise - unsuitable for RF or precision analog rails | Prefer for general-purpose 4.5V loads >120mA where noise is secondary; avoid in signal-chain critical paths. |
Compared with the MAX8510EUA45, the XC6210B452MR-G offers higher output current but sacrifices 2.3× more output noise and lacks BP-enabled ultra-low-noise capability, while the ADP125ARHZ-4.5-R7 trades noise performance for current headroom - making the MAX8510EUA45 uniquely suited for 4.5V, <120mA, sub-12µVRMS applications.

FAQ
What is the maximum input voltage rating for the MAX8510EUA45?
The MAX8510EUA45 has an absolute maximum input voltage of +7V referenced to GND. However, its specified operating input range is 2V to 6V. Operating above 6V risks exceeding junction temperature limits or violating internal voltage tolerances, especially under load. For reliable 4.5V output regulation, maintain VIN between 4.62V (dropout margin) and 6V in normal operation.
Does the MAX8510EUA45 require an external bypass capacitor on the BP pin?
Yes, the MAX8510EUA45 requires a 10nF capacitor connected between BP (Pin 4) and OUT (Pin 5) to achieve its specified 11µVRMS output noise. Without this capacitor, noise rises to 230µVRMS. The BP pin is internally shorted to OUT during shutdown, so the capacitor remains safely biased. Use C0G/NP0 dielectric for stability across temperature.
Can the MAX8510EUA45 be used with ceramic output capacitors smaller than 1µF?
No - the MAX8510EUA45 is only guaranteed stable with ≥1µF ceramic output capacitance (X7R or X5R dielectric). Using smaller values (e.g., 0.47µF) risks oscillation or degraded transient response, particularly at high load currents. The 1µF minimum ensures phase margin >45° across temperature and load conditions per the datasheet stability analysis.
What is the shutdown exit delay time for the MAX8510EUA45?
The MAX8510EUA45 exhibits a typical shutdown exit delay of 300µs (measured from SHDN rising to 90% of final VOUT) under RLOAD = 50Ω, VOUT = 4.5V conditions. This delay results from internal power-on reset and BP capacitor precharge circuitry. Delay increases slightly with heavier loads or lower input voltages but remains under 500µs across the full operating range.
Is the MAX8510EUA45 pin-compatible with other variants in the MAX8510/MAX8511/MAX8512 family?
Yes - the MAX8510EUA45 (SC70-5 package) shares identical pinout with all SC70-packaged MAX8510, MAX8511, and MAX8512 variants, including MAX8510EXKxx+T and MAX8511EXKxx+T. Pin 1 = IN, Pin 2 = GND, Pin 3 = SHDN, Pin 4 = BP (MAX8510) / NC (MAX8511) / FB (MAX8512), Pin 5 = OUT. Functionally, only BP vs. NC vs. FB assignment differs; PCB layout is interchangeable across SC70 versions.
