Product details
Overview
MAX5084ATT+T from Maxim Integrated is a high-voltage linear regulator delivering 5V (preset) or adjustable 2.54V–11V output at up to 200mA, operating from 6.5V to 65V input, with 50μA no-load quiescent current and remote sense (OUT_SENSE) capability - used in automotive body control modules requiring stable 5V rail under wide-input battery conditions.
For engineers reviewing the MAX5084ATT+T datasheet, MAX5084ATT+T pinout, MAX5084ATT+T application, or MAX5084ATT+T equivalent, key selection criteria include guaranteed 200mA load capability at high VIN, thermal shutdown at +160°C, 6-pin TDFN-EP package with exposed paddle for 1.905W dissipation at +70°C, and dual-mode voltage setting via SET pin.
Technical Context
The MAX5084ATT+T implements a BiCMOS-based linear regulation architecture with internal 1.251V reference and error amplifier driving a high-voltage pass transistor. Its Dual Mode™ operation automatically selects between fixed 5V output (SET = GND) or adjustable output (via external resistive divider), determined solely by SET pin voltage level.
Remote sensing is implemented via an internal 15Ω resistor between OUT and OUT_SENSE, enabling Kelvin connection directly at the load to compensate for trace IR drop. Enable logic includes internal 5MΩ pull-down, supporting direct connection to IN for always-on operation while tolerating up to 65V on EN.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 6.5V to 65V - supports 12V/24V/48V industrial and automotive battery systems with transient tolerance. |
| Output Voltage | Fixed 5.0V ±2% (SET = GND) or adjustable 2.54V–11V - enables single-BOM flexibility across multiple system rails. |
| Max Output Current | 200mA guaranteed - sufficient for MCU cores, CAN transceivers, and sensor signal chains without derating at +70°C ambient. |
| No-Load Quiescent Current | 51μA (typ) - minimizes standby power loss in always-on automotive modules. |
| Shutdown Current | 6μA (typ) - enables ultra-low-power sleep modes in telematics and alarm systems. |
| Thermal Shutdown Threshold | +160°C with 10°C hysteresis - provides robust fault recovery during sustained overload without latch-off. |
| Dropout Voltage | 0.9V (typ) at 200mA - ensures regulation down to VIN = 5.9V for 5V output, critical during cold-crank conditions. |
Pinout & Package
MAX5084ATT+T is housed in a thermally enhanced 3mm × 3mm, 6-pin TDFN-EP package with exposed paddle (EP) soldered to PCB ground for optimal heat dissipation (θJC = 8.5°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1. IN | High-voltage input supply | Accepts 6.5V–65V; requires ≥10μF ceramic bypass to GND for stability and transient suppression. |
| 2. EN | Enable control input | Logic-high (>2.4V) enables regulator; internal 5MΩ pull-down allows direct IN tie for always-on use. |
| 3. GND | Power and signal reference | Common return path; EP must be connected to this node for thermal performance and EMI control. |
| 4. SET | Feedback voltage select | Grounding selects 5V preset; resistive divider from OUT→SET→GND sets adjustable output (VOUT = 1.251V × (1 + R1/R2)). |
| 5. OUT_SENSE | Remote output voltage sense | Kelvin-sense input; connect directly to load for <1% regulation error despite PCB trace resistance. |
| 6. OUT | Regulated output | Delivers up to 200mA; requires ≥10μF ceramic capacitor (ESR < 0.5Ω) to GND for loop stability. |
Key Features
| Feature | Design Value |
|---|---|
| Dual Mode™ voltage configuration | Single pin (SET) toggles between factory-trimmed 5V output and user-adjustable 2.54V–11V range - eliminates BOM variants and layout changes. |
| Remote load sensing (OUT_SENSE) | Compensates for up to 150mV IR drop in power delivery traces, maintaining ±1% load regulation accuracy at point-of-load. |
| Thermally enhanced TDFN-EP | 3mm × 3mm footprint delivers 1.905W power dissipation at +70°C ambient - enables compact placement near heat-sensitive components. |
| Wide-temp automotive qualification | Guaranteed operation from –40°C to +125°C junction temperature - validated for engine bay and under-hood applications. |
| Integrated protection suite | Short-circuit current limit (340mA typ), thermal shutdown (+160°C), and safe startup sequencing prevent field failures without external circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM317HVH/NOPB | Adjustable-only (1.25V–57V), no preset 5V mode, higher 80μA IQ, no OUT_SENSE pin, TO-220 package. | Lacks remote sensing and fixed-output convenience; requires external feedback resistors for all configurations. | Choose only if board space allows TO-220 and design accepts higher quiescent current and no Kelvin sensing. |
| LT3080IMSE#PBF | Adjustable-only (0–36V), 1.1A output, 1.1mA IQ, no shutdown, 12-pin MSOP package. | Higher current but incompatible pinout, no enable/shutdown, significantly higher ground current erodes battery life. | Select only for high-current analog biasing where 200mA is insufficient and remote sensing is not required. |
Compared with LM317HVH/NOPB and LT3080IMSE#PBF, the MAX5084ATT+T uniquely combines factory-trimmed 5V output, ultra-low 51μA quiescent current, integrated remote sensing, and compact 3mm × 3mm TDFN - making it optimal for space-constrained, battery-sensitive automotive and industrial control applications where precision and reliability are non-negotiable.

FAQ
What output voltage does MAX5084ATT+T deliver by default?
The MAX5084ATT+T delivers a factory-trimmed 5.0V output when the SET pin is connected to GND. This preset voltage is guaranteed within ±2% over –40°C to +125°C and full load range. The MAX5084ATT+T can also be configured for adjustable output (2.54V–11V) using an external resistive divider from OUT to SET to GND, leveraging its internal 1.251V reference.
Can MAX5084ATT+T operate safely with 65V input continuously?
Yes, the MAX5084ATT+T is rated for continuous operation with input voltages up to 65V. Its absolute maximum IN-to-GND rating is +80V, and electrical specifications - including dropout, load regulation, and PSRR - are validated across the full 6.5V–65V range. Thermal management must be ensured via proper PCB copper area under the exposed paddle to avoid exceeding +150°C junction temperature.
How does the OUT_SENSE pin improve regulation accuracy in MAX5084ATT+T?
The OUT_SENSE pin in the MAX5084ATT+T enables true Kelvin sensing by connecting directly to the load, bypassing voltage drop across PCB traces and connectors. Internally tied to OUT via a 15Ω resistor, it allows the error amplifier to regulate voltage precisely at the point-of-load - reducing regulation error from typical 50–150mV to <5mV under varying load currents, critical for sensitive analog or digital circuits.
What is the minimum output capacitor required for stable operation of MAX5084ATT+T?
The MAX5084ATT+T requires a minimum 10μF ceramic output capacitor with ESR < 0.5Ω for stable operation across –40°C to +125°C and full 200mA load range. X7R or X5R dielectrics are recommended; Z5U/Y5V types require ≥22μF to ensure stability below –10°C. Larger values (e.g., 22μF) further improve PSRR and transient response without compromising stability.
Does MAX5084ATT+T include built-in protection features?
Yes, the MAX5084ATT+T integrates short-circuit current limiting (340mA typical), thermal shutdown (+160°C with 10°C hysteresis), and safe startup sequencing. During overload, it cycles on/off rather than latching off, preventing damage during sustained faults. These protections are fully specified over –40°C to +125°C and require no external components - simplifying design and improving field reliability.
