Product details
Overview
MAX8510EXK45+T from Maxim Integrated is a 4.5V fixed-output, ultra-low-noise, low-dropout linear regulator delivering up to 120mA with 120mV dropout at full load, 11μVRMS output noise (100Hz–100kHz), 78dB PSRR at 1kHz, and 40μA ground current - designed for RF-sensitive power rails in portable wireless transceivers.
For engineers reviewing the MAX8510EXK45+T datasheet, MAX8510EXK45+T pinout, MAX8510EXK45+T application, or MAX8510EXK45+T equivalent, key selection criteria include guaranteed 4.5V ±1% accuracy over temperature, SC70-5 package compatibility with space-constrained PCBs, stability with 1μF ceramic output capacitance, and shutdown current <1μA for battery longevity.
Technical Context
The MAX8510EXK45+T uses a P-channel MOSFET pass transistor (RDS(ON) ≈ 1Ω) enabling low dropout and minimal quiescent current across load and input voltage variations. Its bandgap reference (1.225V) feeds an error amplifier that controls the pass gate via internal feedback, ensuring tight regulation without external resistors.
Noise suppression relies on a dedicated BP pin accepting a 10nF capacitor to OUT, reducing RMS noise to 11μV; PSRR remains ≥54dB up to 100kHz due to integrated bypass architecture and high-gain error amplifier design - critical for powering VCOs, PLLs, and ADC analog supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 4.5V ±1% at +25°C; ±3% over -40°C to +85°C - ensures stable bias for 4.5V-tolerant RF ICs and logic interfaces. |
| Dropout Voltage | 120mV at 120mA load (VIN ≥ 4.62V) - extends usable battery life down to ~4.6V in single-cell Li-ion systems. |
| Output Noise | 11μVRMS (100Hz–100kHz) - meets stringent spectral purity requirements for low-phase-noise signal chains. |
| PSRR | 78dB at 1kHz, 54dB at 100kHz - suppresses switching noise from DC/DC converters feeding intermediate supply rails. |
| Ground Current | 40μA typical at light load; ≤500μA in dropout - minimizes standby power in always-on subsystems. |
| Shutdown Current | <1μA - enables deep-sleep modes in Bluetooth/WLAN modules without compromising wake-up latency. |
| Stability | Guaranteed with 1μF ceramic COUT (X7R/X5R) - eliminates need for large tantalum or electrolytic capacitors. |
Pinout & Package
MAX8510EXK45+T is housed in a RoHS-compliant 5-pin SC70 package (2.0mm × 1.25mm × 0.95mm height), with exposed pad omitted - optimized for thermal performance in thin-profile portable designs.
| 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. |
| 2 - GND | Power and signal ground reference | Serves as primary thermal path; requires direct connection to PCB ground plane for thermal management. |
| 3 - SHDN | Active-low enable control | Pull ≤0.4V to disable regulator; logic-high ≥1.5V enables operation; draws <0.01μA bias current. |
| 4 - BP | Noise bypass terminal | Connects to OUT via 10nF capacitor to reduce output voltage noise by >90% - unique to MAX8510 variant. |
| 5 - OUT | Regulated 4.5V output | Delivers up to 120mA; requires ≥1μF ceramic capacitor to GND for stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 11μVRMS (100Hz–100kHz) enables clean power for VCOs, RF synthesizers, and precision ADCs without additional filtering. |
| High PSRR at RF frequencies | 54dB rejection at 100kHz allows co-location with noisy DC/DC converters in compact RF modules. |
| P-channel MOSFET pass element | Eliminates base-drive current loss - maintains 40μA ground current even at full 120mA load and near-dropout conditions. |
| Single-capacitor stability | Stable with only 1μF X7R/X5R ceramic output capacitor - reduces BOM count and board area vs. legacy LDOs requiring ≥10μF. |
| Integrated protection | Thermal shutdown (160°C trip, 10°C hysteresis) and current limiting (130–300mA range) prevent damage during fault conditions. |
Applications
| Bluetooth Radio Power Supply | Portable Digital Camera Sensor Bias |

|
Use Scenario: Powers ARM Cortex-M4-based WLAN baseband processor (e.g., ESP32-WROOM-32) during 802.11n packet transmission bursts. IC Role / Device Role / Timing Role: Acts as post-regulator for switched-mode supply, rejecting ripple from buck converter switching at 2.4MHz. Use Value: 54dB PSRR at 100kHz attenuates switching harmonics that would otherwise modulate I/Q baseband signals and degrade ACPR. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS79545DBVR | 4.5V fixed, 250mA output, 170mV dropout at 250mA, 30μVRMS noise, SOT-23-5 package | Higher output current but higher noise - suitable where load exceeds 120mA but RF sensitivity is relaxed | Select when higher current headroom is needed and PSRR >70dB above 10kHz is not required |
| ADP160AUJZ-4.5-R7 | 4.5V fixed, 150mA output, 195mV dropout at 150mA, 20μVRMS noise, TSOT-23-5 package | Lower PSRR (48dB @ 100kHz), wider tolerance (±2%), no BP pin - simpler layout but less RF robustness | Choose for cost-sensitive consumer audio where 20μV noise is acceptable and footprint compatibility with SC70 is maintained |
Compared with TPS79545DBVR and ADP160AUJZ-4.5-R7, the MAX8510EXK45+T uniquely delivers the lowest noise (11μVRMS) and highest PSRR (78dB @ 1kHz) in SC70-5, making it irreplaceable for RF-critical 4.5V rails where spectral purity dictates system-level performance.

FAQ
What is the output voltage tolerance of MAX8510EXK45+T over temperature?
The MAX8510EXK45+T guarantees ±3% output voltage accuracy across the full -40°C to +85°C operating range. At +25°C, the tolerance tightens to ±1%, and load regulation contributes ≤0.003%/mA - ensuring stable 4.5V delivery for precision analog loads regardless of thermal drift or current draw changes.
Does MAX8510EXK45+T require an external bypass capacitor, and why?
Yes, the MAX8510EXK45+T requires a 10nF capacitor between BP and OUT pins to achieve its specified 11μVRMS output noise. This bypass path shunts high-frequency noise from the internal bandgap reference and error amplifier - a feature exclusive to the MAX8510 variant and essential for RF-grade power integrity.
Can MAX8510EXK45+T operate with input voltages below 4.5V?
Yes, the MAX8510EXK45+T operates with input voltages as low as 2V, but regulation is only maintained when VIN ≥ VOUT + dropout voltage. For 4.5V output at 120mA, minimum VIN is 4.62V; below that, output drops linearly - enabling graceful brownout behavior in Li-ion battery discharge profiles.
How does the shutdown function behave on MAX8510EXK45+T?
When SHDN is pulled low (<0.4V), the MAX8510EXK45+T disables its voltage reference, error amplifier, and pass transistor, reducing supply current to <1μA and placing OUT in high-impedance state. Exit delay is 300μs typical - fast enough for duty-cycled RF subsystems without compromising sleep-mode efficiency.
Is MAX8510EXK45+T stable with all ceramic capacitor dielectrics?
The MAX8510EXK45+T is guaranteed stable with 1μF X7R or X5R ceramic capacitors across -40°C to +85°C. Z5U and Y5V dielectrics exhibit significant capacitance loss at low temperatures; for those, ≥2.2μF is recommended to maintain phase margin - confirmed by the "Region of Stable COUT ESR vs. Load Current" plot in the datasheet.
