Product details
Overview
MAX8860EUA30+T from Maxim Integrated is a low-noise, low-dropout linear regulator delivering 300mA at a fixed 3.0V output, operating from 2.5V to 6.5V input. It features 60µVRMS output noise, 105mV dropout at 200mA, 120µA no-load supply current, and reverse battery protection - designed for DSP core power and handheld instrumentation.
For engineers reviewing the MAX8860EUA30+T datasheet, MAX8860EUA30+T pinout, MAX8860EUA30+T application, or MAX8860EUA30+T equivalent, this page provides verified electrical parameters, µMAX package layout, fault-detection behavior, Dual Mode™ configurability, and real-world load-transient performance data.
Technical Context
The MAX8860EUA30+T integrates an internal P-channel MOSFET pass transistor (RDS(ON) ≈ 0.5Ω) enabling low dropout and eliminating base-drive current loss. Its error amplifier compares a 1.25V bandgap reference against feedback from either internal resistors (for 3.0V preset mode) or external SET-pin dividers.
Dual Mode™ logic monitors VSET; when ≤60mV, it selects internal feedback for fixed 3.0V regulation. Fault detection triggers FAULT low during dropout, thermal shutdown (>170°C), or insufficient input-output differential (<130mV at 200mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.00V ±3% over –40°C to +85°C; ensures stable DSP core rail under temperature variation |
| Max Output Current | 300mA continuous; supports high-pulse loads in palmtop computers without thermal derating |
| Dropout Voltage | 105mV at 200mA; enables operation down to 3.105V input with 3.0V output - extends battery life in single-cell Li-ion systems |
| Output Noise | 60µVRMS (10Hz–100kHz); meets low-noise analog supply requirements for precision ADCs or RF front-ends |
| Quiescent Current | 120µA typical at no load; minimizes standby drain in always-on wireless handset subsystems |
| Fault Detection Threshold | 130mV input-output differential at 200mA; tracks dropout voltage to warn before regulation loss |
| Shutdown Current | 10nA logic-controlled; enables ultra-low-power sleep states in electronic planners |
Pinout & Package
MAX8860EUA30+T is housed in an 8-pin µMAX package (3.0mm × 3.0mm × 1.1mm max height), optimized for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 - OUT | Regulator output | Delivers regulated 3.0V; requires ≥2.2µF low-ESR ceramic capacitor to GND for stability |
| 2 - IN | Input supply | Accepts 2.5V–6.5V; bypassed with 2.2µF capacitor to GND to suppress source impedance effects |
| 3 - GND | Power ground | Common return for all internal circuitry; must connect to low-impedance PCB ground plane |
| 5 - SET | Voltage selection control | Grounded for 3.0V fixed mode; open or >60mV disables internal feedback - critical for reliable Dual Mode™ operation |
| 6 - CC | Compensation node | Connects 33nF capacitor to GND to stabilize loop response and reduce load-transient overshoot |
| 7 - SHDN | Logic shutdown input | Driven low (≤0.4V) to disable regulator; draws <100nA bias current - compatible with GPIOs |
| 8 - FAULT | Open-drain fault indicator | Asserts low during dropout, thermal shutdown, or overload; requires external pull-up to OUT for level translation |
Key Features
| Feature | Design Value |
|---|---|
| Dual Mode™ configuration | Single device supports both fixed 3.0V output (SET = GND) and adjustable 1.25V–6.5V (external resistor divider), reducing BOM count |
| Reverse battery protection | Limits reverse current to <1mA if VIN or SHDN falls below GND - prevents damage from misinserted batteries in handheld instruments |
| Thermal shutdown with hysteresis | Triggers at +170°C junction temperature and re-enables after ~20°C cooldown - avoids oscillation during sustained overload |
| Low-noise integrator compensation | 33nF CC capacitor reduces output noise density and improves PSRR above 10kHz without requiring complex external networks |
| FAULT output with tracking threshold | FAUT low threshold scales with load current (e.g., 130mV @ 200mA), providing early warning before regulation collapse |
Applications
| Wireless Handsets | DSP Core Power |
|---|---|
Use Scenario: Primary voltage rail for baseband processor and audio codec in GSM/EDGE handsets with single Li-ion cell. IC Role / Device Role / Timing Role: Low-noise 3.0V LDO supplying sensitive analog sections of DSP subsystems. Use Value: 60µVRMS noise prevents audible artifacts; 105mV dropout extends usable battery range by ~15 minutes at end-of-life. |
Use Scenario: Dedicated 3.0V supply for TI C55x or Analog Devices SHARC DSP cores in portable test equipment. IC Role / Device Role / Timing Role: Stable, low-ripple power source ensuring deterministic instruction execution and ADC sampling accuracy. Use Value: 120µA quiescent current minimizes idle power; FAULT signal enables firmware-initiated graceful shutdown before brownout. |
| PCMCIA Cards | Hand-Held Instruments |
Use Scenario: 3.0V rail generation for Type II PCMCIA memory or modem cards inserted into laptops or industrial terminals. IC Role / Device Role / Timing Role: Input-voltage-flexible regulator accepting host-supplied 3.3V or battery-derived 2.5V–6.5V inputs. Use Value: Reverse battery protection prevents card damage during hot-swap insertion errors; µMAX footprint fits tight card-edge layouts. |
Use Scenario: Main supply for multimeter or oscilloscope front-end ASICs requiring precise 3.0V reference stability. IC Role / Device Role / Timing Role: Regulator with tight line/load regulation (±0.1%/V, ±0.0006%/mA) maintaining measurement accuracy across battery discharge. Use Value: 2.2µF output capacitor suffices for stability - eliminates need for larger, costlier tantalum parts in field-serviceable units. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, 300mA LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS76330DBVR | Higher 220mV dropout at 200mA; 170µA quiescent current; no FAULT pin or reverse battery protection | Lacks fault monitoring and reverse polarity hardening - unsuitable for unattended handheld instruments | Choose only if board space allows SO-8 and system lacks fault-reporting requirements |
| MCP1703T-3002E/MB | Lower 600mA rating but higher 175µA quiescent current; no Dual Mode™ or FAULT output | Fixed 3.0V only; no adjustable mode or integrated fault signaling - limits design reuse across voltage variants | Select when needing higher current headroom and FAULT functionality is handled externally |
Compared with TPS76330DBVR and MCP1703T-3002E/MB, MAX8860EUA30+T uniquely combines 3.0V precision regulation, 10nA shutdown, reverse battery protection, and FAULT reporting in a 3mm × 3mm µMAX package - making it optimal for compact, safety-critical portable systems.

FAQ
What is the guaranteed output voltage tolerance for MAX8860EUA30+T over temperature?
The MAX8860EUA30+T guarantees a 3.0V output within ±3% over the full –40°C to +85°C operating range, with typical performance of 2.95V to 3.05V at +25°C. This tolerance is ensured by factory-trimmed internal feedback resistors and applies only in preset mode with SET tied to GND.
Can MAX8860EUA30+T be used in adjustable-output configurations?
Yes, MAX8860EUA30+T supports adjustable output from 1.25V to 6.5V via external resistors on the SET pin, enabled by its Dual Mode™ architecture. However, doing so disables the factory-trimmed 3.0V setting - the part must be operated in preset mode (SET = GND) to deliver its specified 3.0V output.
What is the minimum output capacitor required for stable operation of MAX8860EUA30+T?
MAX8860EUA30+T requires a minimum 2.2µF ceramic output capacitor with ESR < 0.5Ω for stable operation across –40°C to +85°C and up to 300mA load. Larger values improve transient response but are not mandatory; X7R dielectric in 1206 case is validated per datasheet.
How does the FAULT pin behave during thermal shutdown?
During thermal shutdown, the FAULT pin of MAX8860EUA30+T goes low to indicate loss of regulation - identical to its behavior during dropout or current limit. The FAULT signal remains asserted until junction temperature drops ~20°C below the +170°C trip point, enabling firmware to log thermal events.
Does MAX8860EUA30+T require a minimum load current for regulation?
MAX8860EUA30+T requires no minimum load current when input voltage is ≤5.5V. However, at VIN > 5.5V in preset mode, a 50µA minimum load is needed to maintain regulation - a requirement satisfied by typical PCB leakage or downstream bias currents in most handheld instrument designs.
