Product details
Overview
The MAX25210ATAA9/V+ from Analog Devices is an automotive-grade, high-voltage linear regulator delivering 300mA output current with 10µA typical quiescent current, +3.5V to +36V input range, +42V transient tolerance, and fixed 93.5% reset threshold - designed for always-on power domains in engine control units and ADAS domain controllers.
For engineers reviewing the MAX25210ATAA9/V+ datasheet, MAX25210ATAA9/V+ pinout, MAX25210ATAA9/V+ application, or MAX25210ATAA9/V+ equivalent, this page delivers verified electrical specs, thermal behavior under load-dump, RESET timing validation, and AEC-Q100-compliant operating margins across -40°C to +125°C.
Technical Context
The MAX25210ATAA9/V+ implements a high-side pass transistor architecture with internal voltage reference (0.600V ±2%), precision bandgap-based feedback control, and dual-stage thermal shutdown (trip at +170°C, hysteresis 20°C). Its ENABLE input withstands +42V and features an internal 0.25µA pulldown, enabling direct connection to battery rails without external biasing.
RESET functionality uses an open-drain output with fixed 93.5% falling-threshold detection relative to VOUT and a factory-set 60µs timeout period extendable via TIMEOUT pin capacitor. The device supports three configuration modes - 3.3V fixed, 5V fixed, or adjustable (0.6V–11V) - selected by SET and SETOV pin states per the validated pin logic table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +3.5V to +36V continuous; +42V tolerant for ≤1s - survives ISO 7637-2 Load Dump Pulse 5a. |
| Output Current | 300mA maximum - sustains full load at +125°C ambient with proper PCB thermal design (θJA = 41°C/W, 4-layer board). |
| Quiescent Current | 10µA typical at no load - enables >10-year battery standby in telematics modules with <1µA system sleep leakage budget. |
| RESET Threshold | 93.5% of VOUT (falling edge), with 5% hysteresis - ensures clean microcontroller reset release after brownout recovery. |
| Dropout Voltage | 280mV at 200mA (typ) - maintains regulation during cold-crank down to +3.5V input in 12V automotive systems. |
| Operating Temperature | -40°C to +125°C junction - qualified to AEC-Q100 Grade 1, supporting placement near powertrain ECUs without derating. |
| Package Thermal Resistance | θJA = 41°C/W (4-layer board) - requires exposed pad soldered to ≥4 thermal vias for full 300mA capability at +125°C ambient. |
Pinout & Package
MAX25210ATAA9/V+ uses an 8-pin TDFN-EP package (3mm × 3mm, 0.5mm pitch) with exposed thermal pad (EP) on underside for enhanced heat dissipation. Pin 1 is IN; pin 8 is OUT; EP must be connected to GND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | High-voltage input supply | Bypass with ≥1µF low-ESR ceramic; withstands +42V transients; connects directly to battery rail. |
| 2 ENABLE | Active-high enable control | Logic-high (>2.4V) enables regulator; internal 0.25µA pulldown holds shutdown when floating or open-drain driven. |
| 3 SET | Feedback network mode selector | GND = fixed-output mode (3.3V/5V); >2.4V = adjustable mode using external resistive divider. |
| 4 RESET | Open-drain active-low reset signal | Pulled low during VOUT undervoltage, ENABLE low, or thermal shutdown; requires external pull-up ≥1.5V. |
| 5 TIMEOUT | Reset timeout delay adjust | Unconnected = 60µs default; capacitor to GND extends delay per tRP = 1.25 × CTIMEOUT/ITO. |
| 6 SETOV | Output voltage selection / feedback node | GND = 3.3V fixed; OUT = 5V fixed; external divider = adjustable (0.6V–11V); 0.600V reference accuracy ±2%. |
| 7 GND | Power and signal ground | Must connect exposed pad (EP) to same GND net; primary return path for IN, OUT, and internal regulators. |
| 8 OUT | Regulated output | Stable with ≥2.2µF low-ESR ceramic; supports 300mA load; feeds MCU core, CAN transceivers, or sensor interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 10µA typical at no load - meets OEM requirements for <100µA module sleep current in always-on domains. |
| Integrated RESET generator | Eliminates discrete reset IC; 93.5% threshold + 60µs minimum timeout satisfies SAE J1939 and AUTOSAR BSW reset timing. |
| Configurable output voltage | Single device supports 3.3V, 5V, or 0.6V–11V via pin-strapping - reduces BOM variants and simplifies platform design. |
| Robust fault protection | Thermal shutdown (+170°C trip), short-circuit current limiting (400mA typ), and +42V input tolerance - no external protection needed. |
| Automotive qualification | AEC-Q100 Grade 1 certified (-40°C to +125°C), with 95,000-hour lifetime at TJ = +125°C - validated for 15-year vehicle service life. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, ultra-low-IQ linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX25210ATAA8/V+ | Same package, 300mA output, but 87.5% RESET threshold instead of 93.5%. | Suitable for systems requiring earlier reset assertion during VOUT sag (e.g., legacy MCU with wider reset window). | Select only if 87.5% threshold aligns with host MCU's VDD monitor specification; otherwise MAX25210ATAA9/V+ preferred for tighter brownout detection. |
| TLV73333PDBVR | 300mA, 3.3V fixed, 45µA IQ, +5.5V max input - lacks automotive temp range, +42V tolerance, and RESET output. | Limited to non-automotive, low-voltage industrial or consumer applications with benign supply conditions. | Not a functional substitute for MAX25210ATAA9/V+ in automotive environments; use only in cost-sensitive, non-automotive designs where AEC-Q100 and load-dump immunity are not required. |
Compared with MAX25210ATAA8/V+, the MAX25210ATAA9/V+ provides higher reset threshold accuracy for critical brownout detection; compared with TLV73333PDBVR, it delivers automotive-grade robustness, wide-input operation, and integrated reset - making it irreplaceable in safety-critical vehicle subsystems.

FAQ
What is the exact RESET threshold voltage for MAX25210ATAA9/V+?
The MAX25210ATAA9/V+ has a fixed RESET falling-threshold of 93.5% of the regulated output voltage, with ±1.5% tolerance (92%–95%). For a 5.0V output, this corresponds to 4.675V (min) to 4.75V (typ) before RESET asserts low. This value is factory-trimmed and does not require external calibration.
Can MAX25210ATAA9/V+ operate with only a 2.2µF output capacitor?
Yes - MAX25210ATAA9/V+ is stable with a minimum 2.2µF low-ESR ceramic capacitor on the OUT pin when configured for fixed 3.3V or 5.0V output. This eliminates need for larger bulk capacitors, reducing PCB area and BOM cost while maintaining phase margin >45° across -40°C to +125°C.
How is the output voltage configured on MAX25210ATAA9/V+?
MAX25210ATAA9/V+ supports three modes: (1) 3.3V fixed: SET = GND, SETOV = GND; (2) 5.0V fixed: SET = GND, SETOV = OUT; (3) adjustable (0.6V–11V): SET > 2.4V, SETOV connected to resistive divider between OUT and GND. No external components needed for fixed modes.
Does MAX25210ATAA9/V+ include thermal protection?
Yes - MAX25210ATAA9/V+ incorporates thermal shutdown that disables the pass transistor at +170°C junction temperature and re-enables it after cooling by 20°C hysteresis. This protects against damage during sustained overload or poor heatsinking, and is fully characterized per AEC-Q100 stress testing.
What package type and footprint does MAX25210ATAA9/V+ use?
MAX25210ATAA9/V+ uses an 8-pin TDFN-EP package (3mm × 3mm, 0.5mm pitch) with exposed thermal pad. Land pattern follows JEDEC MO-229, outline number 21-0137, and requires soldering the EP to GND via ≥4 thermal vias for optimal thermal performance at full 300mA load.
