Product details
Overview
MAX8510EXK25-T from Maxim Integrated is a 2.5V fixed-output, ultra-low-noise, low-dropout linear regulator featuring a P-channel MOSFET pass element, 120mV dropout at 120mA, 11µVRMS output noise (100Hz–100kHz), and 78dB PSRR at 1kHz. It delivers stable 2.5V power to noise-sensitive analog circuitry in portable RF and precision signal-chain applications.
For engineers reviewing the MAX8510EXK25-T datasheet, MAX8510EXK25-T pinout, MAX8510EXK25-T application, or MAX8510EXK25-T equivalent, key selection criteria include its guaranteed 120mA output capability, 40µA ground current across load and temperature, SC70-5 package footprint, and BP-capacitor–enabled ultra-low-noise performance - all critical for battery-powered, space-constrained designs requiring clean supply rails.
Technical Context
The MAX8510EXK25-T implements a bandgap reference (1.225V) with error amplifier feedback to an internal resistor divider, enabling precise 2.5V regulation. Its P-channel MOSFET pass transistor (typ. 1Ω RDS(ON)) eliminates base-drive current, ensuring low quiescent operation and consistent dropout behavior across temperature.
Shutdown control is implemented via a CMOS-compatible SHDN pin with logic-low threshold ≤0.4V and bias current <0.1µA at +85°C. The BP pin enables active noise bypassing using a 10nF capacitor to OUT, directly reducing output voltage noise to 11µVRMS without requiring external LDO post-filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5V ±3% over -40°C to +85°C; supports precision analog loads without external feedback components. |
| Max Output Current | 120mA continuous; sufficient to power multiple low-power ICs (e.g., ADCs, RF transceivers) from a single regulator. |
| Dropout Voltage | 120mV at 120mA load; enables operation down to VIN = 2.62V while maintaining regulated 2.5V output. |
| Output Noise | 11µVRMS (100Hz–100kHz); meets stringent noise requirements for high-resolution SAR ADCs and VCO bias supplies. |
| PSRR | 78dB at 1kHz; suppresses switching noise from upstream DC/DC converters in mixed-signal systems. |
| Ground Current | 40µA typical at no load; ensures >10-year battery life in always-on sensor nodes with microamp-level sleep currents. |
| Input Voltage Range | 2V to 6V; compatible with single-cell Li-ion (3.0–4.2V), two-cell alkaline (2.0–3.2V), and 3.3V/5V system rails. |
Pinout & Package
MAX8510EXK25-T is housed in a RoHS-compliant, lead-free 5-pin SC70 package (2.0mm × 1.25mm × 0.9mm), optimized for high-density PCB layouts. The exposed pad is absent in SC70; thermal management relies on copper pour under pins 2 (GND) and 5 (OUT).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Unregulated input supply | Accepts 2V–6V input; requires 1µF ceramic decoupling close to pin for stability and transient response. |
| 2 GND | Ground reference and thermal path | Primary return for load current and regulator core; must connect to large PCB ground plane for thermal and noise integrity. |
| 3 SHDN | Active-low shutdown control | Pull ≤0.4V to disable regulator; draws <0.1µA in shutdown, enabling ultra-low-power system sleep modes. |
| 4 BP | Noise bypass terminal | Connects to OUT via 10nF capacitor; enables 11µVRMS noise performance by shunting high-frequency reference noise. |
| 5 OUT | Regulated 2.5V output | Delivers up to 120mA; requires 1µF ceramic capacitor to GND; output impedance remains low across 10Hz–1MHz for dynamic load support. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 11µVRMS (100Hz–100kHz) with 10nF BP capacitor - eliminates need for secondary RC filtering in audio and RF bias paths. |
| Stable with minimal capacitance | Guaranteed stability with only 1µF ceramic output capacitor - reduces BOM count and board area vs. traditional LDOs requiring ≥10µF. |
| P-channel MOSFET architecture | 1Ω typ. RDS(ON) pass device - enables low dropout and eliminates base-drive current loss, improving light-load efficiency. |
| Integrated protection | Thermal shutdown (160°C trip, 10°C hysteresis) and current limit (130–300mA) - allows safe operation under fault conditions without external circuitry. |
| Low shutdown current | <1µA shutdown supply current - preserves battery energy during extended idle periods in portable medical and IoT devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A4700RGWR | 20µVRMS noise (10Hz–100kHz), 1A output, 6V max input, WSON-10 package | Higher output current and wider input range; larger footprint and higher cost | Select when >120mA load or >6V input is required; not suitable for SC70-area-constrained designs. |
| MCP1703T-2502E/MB | 25µVRMS noise, 250mA output, 16V max input, SOT-23-5 package | Higher noise floor and lower PSRR (60dB @ 1kHz); lacks BP pin for noise optimization | Choose for cost-sensitive, non-noise-critical 2.5V rails where 25µV noise is acceptable and 250mA headroom is needed. |
Compared with TPS7A4700RGWR and MCP1703T-2502E/MB, the MAX8510EXK25-T uniquely balances ultra-low noise (11µVRMS), SC70-5 footprint, and 40µA quiescent current - making it optimal for miniaturized, battery-operated RF and precision analog systems where board area and noise are primary constraints.

FAQ
What is the output voltage tolerance of the MAX8510EXK25-T over temperature and load?
The MAX8510EXK25-T guarantees ±3% output voltage accuracy over the full -40°C to +85°C operating temperature range and for load currents from 100µA to 80mA. At room temperature and 1mA load, typical deviation is ±1%. This tight tolerance ensures reliable operation of 2.5V-dependent analog components without external trimming or calibration.
Can the MAX8510EXK25-T operate stably with a 1µF ceramic output capacitor?
Yes, the MAX8510EXK25-T is fully characterized and guaranteed stable with a single 1µF X7R or X5R ceramic capacitor on the output. Unlike many LDOs requiring ≥10µF and specific ESR ranges, this device uses an advanced internal compensation scheme that eliminates external stability components - reducing bill-of-materials cost and PCB area.
What is the purpose of the BP pin on the MAX8510EXK25-T, and how should it be used?
The BP (Bypass) pin on the MAX8510EXK25-T connects to an internal noise-reduction circuit tied to the bandgap reference. To achieve the specified 11µVRMS output noise, a 10nF ceramic capacitor must be placed between BP and OUT. This capacitor shunts high-frequency reference noise before it reaches the error amplifier, directly lowering output spectral density without affecting regulation loop dynamics.
Does the MAX8510EXK25-T require an input capacitor, and if so, what value is recommended?
Yes, the MAX8510EXK25-T requires a minimum 1µF ceramic input capacitor (X7R/X5R) placed as close as possible to the IN and GND pins. This capacitor reduces input impedance at high frequencies, improves line-transient response, and prevents instability caused by source inductance - especially critical when powered from switch-mode supplies or long PCB traces.
How does the MAX8510EXK25-T behave during shutdown, and what is its shutdown current?
When the SHDN pin is pulled low (≤0.4V), the MAX8510EXK25-T disables its voltage reference, error amplifier, gate driver, and pass transistor, placing the OUT pin in a high-impedance state. Shutdown supply current is guaranteed <1µA at +25°C and <0.05µA at +85°C - enabling multi-year battery life in always-connected IoT edge nodes using the MAX8510EXK25-T for periodic wake-up power.
