Product details
Overview
MAX8510EXK16-T from Maxim Integrated is a 1.6V ultra-low-noise, low-dropout linear regulator with P-channel MOSFET pass element, delivering up to 120mA output current, 120mV dropout at full load, 11µVRMS output noise (100Hz–100kHz), and 78dB PSRR at 1kHz. It operates from 2V to 6V input and targets precision analog rails in battery-powered portable radios and digital cameras.
For engineers reviewing the MAX8510EXK16-T datasheet, MAX8510EXK16-T pinout, MAX8510EXK16-T application, or MAX8510EXK16-T equivalent, key selection criteria include guaranteed 120mA output capability, 40µA ground current across load and temperature, SC70-5 package compatibility, and BP-capacitor–enabled ultra-low-noise performance for RF-sensitive signal chains.
Technical Context
The MAX8510EXK16-T implements a bandgap-referenced error amplifier driving a 1Ω typ P-channel MOSFET pass transistor, eliminating base-drive current and enabling stable 40µA quiescent operation across 0–120mA load. Its BP pin connects to a 10nF capacitor to shunt high-frequency noise from the internal reference, directly enabling the 11µVRMS noise spec.
Shutdown logic disables the reference, error amp, and gate driver when SHDN < 0.4V, reducing supply current to <1µA; exit delay is 300µs. Thermal shutdown activates at +160°C with 10°C hysteresis, and current limiting holds output at 130–300mA during overload without damage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.6V ±3% over -40°C to +85°C; enables direct replacement of 1.6V logic or analog supply rails. |
| Max Output Current | 120mA continuous; supports moderate-power RF front-ends or image sensor biasing without thermal derating in SC70. |
| Dropout Voltage | 120mV at 120mA load; extends usable battery life down to VIN = 1.72V for 1.6V rail in single-cell Li-ion systems. |
| Output Noise | 11µVRMS (100Hz–100kHz); meets stringent SNR requirements for ADC reference supplies and low-phase-noise VCO biasing. |
| PSRR | 78dB at 1kHz, 54dB at 100kHz; suppresses switching regulator ripple and digital supply coupling into sensitive analog stages. |
| Ground Current | 40µA typical at light load, 220µA in dropout; minimizes standby power loss in always-on subsystems. |
| Shutdown Current | <1µA; enables deep-sleep modes in Bluetooth accessories and portable medical sensors. |
Pinout & Package
MAX8510EXK16-T is housed in a 5-pin SC70-5 package (2.0mm × 1.25mm × 0.95mm, lead-free), optimized for space-constrained portable PCBs. The exposed pad variant is not used in this orderable part.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Unregulated input supply | Accepts 2V–6V; requires 1µF ceramic input capacitor for stability and line-transient suppression. |
| 2 - GND | Power and thermal reference ground | Serves dual role: electrical return path and primary heat conduction path; must connect to large copper area. |
| 3 - SHDN | Active-low enable control | Pulled high to IN for normal operation; driven below 0.4V to enter sub-1µA shutdown with 300µs wake-up delay. |
| 4 - BP | Noise bypass terminal | Connects 10nF capacitor to OUT to reduce reference noise; shorted to OUT during shutdown. |
| 5 - OUT | Regulated 1.6V output | Delivers up to 120mA; stabilized by 1µF ceramic capacitor; high-impedance in shutdown mode. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 11µVRMS (100Hz–100kHz) enabled by BP pin and internal bandgap/noise-bypass architecture-critical for high-SNR audio and RF biasing. |
| High PSRR at audio frequencies | 78dB rejection at 1kHz ensures clean power delivery to op-amps and ADC drivers in mixed-signal SoC interfaces. |
| Low dropout with P-MOSFET | 120mV dropout at 120mA eliminates need for higher-input-voltage rails, simplifying power tree in single-cell battery systems. |
| Stable with minimal capacitance | Guaranteed stability with only 1µF ceramic output capacitor across all loads-reduces BOM count and board area vs. electrolytic-dependent LDOs. |
| Integrated protection | Thermal shutdown (+160°C, 10°C hysteresis) and current limit (130–300mA) prevent damage during fault conditions without external circuitry. |

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 |
|---|---|---|---|
| TPS79516DBVR | 1.6V fixed, 250mA output, 170mV dropout at 250mA, 30µVRMS noise, SOT-23-5 package | Higher output current but higher noise; lacks BP pin for noise optimization | Select when higher load current is required and 30µV noise is acceptable for the signal chain. |
| MCP1700T-1602E/MB | 1.6V fixed, 250mA output, 175mV dropout at 250mA, 95µVRMS noise, SOT-23-3 package | No BP pin, no shutdown, higher noise, smaller footprint but no enable control | Select for cost-sensitive, non-shutdown applications where ultra-low noise is not critical. |

FAQ
What is the output voltage tolerance of the MAX8510EXK16-T over temperature and load?
The MAX8510EXK16-T maintains ±3% output voltage accuracy across load currents from 100µA to 80mA and temperatures from -40°C to +85°C. At 25°C and 1mA load, tolerance tightens to ±1%. This specification ensures reliable operation for 1.6V logic and analog circuits without external trimming.
Does the MAX8510EXK16-T require an external bypass capacitor on the BP pin, and what value is recommended?
Yes, the MAX8510EXK16-T requires a 10nF capacitor between BP and OUT to achieve its specified 11µVRMS output noise. Values between 1nF and 100nF are supported, but 10nF is optimal; deviations outside this range degrade noise performance or stability. The BP pin is internally shorted to OUT during shutdown.
Can the MAX8510EXK16-T be used with ceramic output capacitors smaller than 1µF?
No-the MAX8510EXK16-T is guaranteed stable only with ≥1µF ceramic output capacitance. Using smaller values risks oscillation under varying load conditions. X7R or X5R dielectrics are recommended; Z5U/Y5V types may require ≥2.2µF below -10°C for stability.
What is the maximum input voltage rating for the MAX8510EXK16-T, and what happens if exceeded?
The absolute maximum input voltage for the MAX8510EXK16-T is +7V relative to GND. Exceeding this risks permanent damage. Operating continuously above 6V violates the recommended input range (2V–6V) and may cause excessive power dissipation, thermal shutdown, or accelerated parametric drift-even if below the absolute max.
How does the shutdown function of the MAX8510EXK16-T behave during power-up and power-down sequences?
The MAX8510EXK16-T enters shutdown when SHDN is pulled below 0.4V and exits after ~300µs once SHDN rises above 1.5V. During entry, output transitions to high-impedance within microseconds; during exit, the BP capacitor precharges and output ramps smoothly. Connecting SHDN to IN ensures immediate enable at power-on.
