Product details
Overview
The MAX8510EXK45-T from Maxim Integrated is a preset 4.5V ultra-low-noise, low-dropout linear regulator featuring a P-channel MOSFET pass device, 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 and precision signal-chain applications.
For engineers reviewing the MAX8510EXK45-T datasheet, MAX8510EXK45-T pinout, MAX8510EXK45-T application, or MAX8510EXK45-T equivalent, key selection criteria include its fixed 4.5V output, SC70-5 package footprint, sub-1µA shutdown current, 40µA ground current under light load, and stability with only 1µF ceramic output capacitance.
Technical Context
The MAX8510EXK45-T employs an internal 1.225V bandgap reference and error amplifier to regulate output against line/load variations, with feedback provided by a factory-trimmed internal resistor divider. Its P-channel MOSFET pass transistor eliminates base-drive current, enabling ultra-low quiescent current across operating conditions.
Dropout behavior is governed by RDS(ON) × ILOAD, yielding 120mV at 120mA; noise performance is enhanced via dedicated BP pin connected to a 10nF capacitor between BP and OUT, bypassing the reference and error amplifier inputs to suppress 100Hz–100kHz RMS noise to 11µV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 4.5V ±3% over -40°C to +85°C - ensures stable supply for 4.5V-tolerant analog ICs without external feedback components. |
| Max Output Current | 120mA continuous - sufficient for powering RF front-ends, ADC/DAC bias rails, or low-power microcontrollers. |
| Dropout Voltage | 120mV at 120mA load - 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) - minimizes phase noise in VCOs and jitter in clock buffers when powering sensitive analog stages. |
| PSRR | 78dB at 1kHz, 54dB at 100kHz - rejects switching noise from adjacent DC/DC converters feeding mixed-signal subsystems. |
| Ground Current | 40µA typical at no load - preserves battery runtime in always-on sensor nodes or standby power domains. |
| Shutdown Current | <1µA - enables deep-sleep modes in portable devices without compromising wake-up latency. |
Pinout & Package
MAX8510EXK45-T is housed in a RoHS-compliant 5-pin SC70-5 package (2.0mm × 1.25mm × 0.9mm), with exposed pad omitted - optimized for space-constrained PCB layouts in handheld and wearable electronics.
| 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 transient response. |
| 2 - GND | Ground reference and thermal path | Primary return for all internal circuits; connects to PCB ground plane to manage thermal dissipation (θJA = 324°C/W). |
| 3 - SHDN | Active-low shutdown control | Pull ≤0.4V to disable regulator; draws <0.01µA bias current - compatible with GPIOs of ultra-low-power MCUs. |
| 4 - BP | Noise bypass terminal | Connects 10nF capacitor to OUT to shunt reference/amp noise; shorted to OUT during shutdown - unique to MAX8510 variant. |
| 5 - OUT | Regulated 4.5V output | Delivers up to 120mA; requires ≥1µF ceramic output capacitor to ground for stability across all loads and temperatures. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output voltage noise | 11µVRMS (100Hz–100kHz) achieved via dedicated BP pin and internal noise-bypass architecture - critical for RF synthesizer and high-resolution ADC power rails. |
| High PSRR at audio and switching frequencies | 78dB at 1kHz and 54dB at 100kHz - suppresses ripple from buck converters and digital supply coupling into analog signal paths. |
| Stable with minimal external capacitance | Guaranteed stability using only 1µF ceramic COUT - reduces BOM count and board area versus regulators requiring 10µF+ tantalum or polymer caps. |
| Low-quiescent-current P-channel architecture | 40µA ground current at no load and <1µA in shutdown - extends battery life in intermittent-sensing applications like IoT endpoints. |
| Robust protection suite | Integrated current limiting (130–300mA), thermal shutdown at +160°C with 10°C hysteresis, and infinite short-circuit tolerance - eliminates need for external fault management circuitry. |

FAQ
What is the output voltage tolerance of the MAX8510EXK45-T over temperature and load?
The MAX8510EXK45-T maintains ±3% output voltage accuracy across -40°C to +85°C ambient temperature and for load currents from 100µA to 80mA. At 120mA, deviation remains within specification due to low dropout and robust load regulation (0.003%/mA). This tolerance ensures reliable operation of 4.5V-tolerant analog ICs without external trimming.
Can the MAX8510EXK45-T operate with ceramic capacitors smaller than 1µF?
No - the MAX8510EXK45-T is specified and guaranteed stable only with ≥1µF ceramic output capacitance (X5R/X7R dielectric recommended). Using smaller values risks instability, overshoot, or oscillation under dynamic load conditions. Input capacitance must also be ≥1µF for optimal line-transient response and PSRR.
Is the BP pin on the MAX8510EXK45-T required for basic operation?
Yes - the BP pin is mandatory for achieving the specified 11µVRMS output noise. It must be connected to OUT via a 10nF capacitor. Omitting this capacitor degrades noise performance to ~230µVRMS. During shutdown, BP is internally shorted to OUT, so no additional isolation is needed.
What thermal derating applies to the MAX8510EXK45-T in SC70-5 package?
In the SC70-5 package, the MAX8510EXK45-T has θJA = 324°C/W. At +70°C ambient, maximum continuous power dissipation is 0.247W; above that, derate by 3.1mW/°C. For example, at +85°C ambient, max power drops to 0.203W - corresponding to ~45mA at 4.5V output with 2V input headroom.
Does the MAX8510EXK45-T support reverse-voltage protection?
No - the MAX8510EXK45-T lacks integrated reverse-voltage protection. Absolute maximum rating for IN-to-GND is -0.3V; applying reverse polarity may cause latch-up or permanent damage. External protection (e.g., series Schottky diode) is required if system-level reverse-voltage exposure is possible.
