Product details
Overview
The MAX25210ATAD8/V+ from Analog Devices is an automotive-grade, high-voltage linear regulator delivering 50mA output current with ultra-low 10µA quiescent current and +3.5V to +36V input range. It supports fixed +3.3V/+5V or adjustable +0.6V to +11V outputs, features open-drain active-low RESET with 87.5% threshold and 60µs default delay, and operates across -40°C to +125°C for engine control unit power management.
For engineers reviewing the MAX25210ATAD8/V+ datasheet, MAX25210ATAD8/V+ pinout, MAX25210ATAD8/V+ application, or MAX25210ATAD8/V+ equivalent, this page delivers verified electrical parameters, thermal performance data, RESET timing behavior, TDFN-EP package layout guidance, and validated alternative parts for low-IQ automotive power design.
Technical Context
The MAX25210ATAD8/V+ implements a high-side pass transistor architecture with internal voltage reference and error amplifier, enabling stable regulation under cold-crank (down to +3.5V) and load-dump (+42V transient) conditions. Its SET/SETOV dual-input configuration determines fixed-output mode (3.3V or 5V) or adjustable mode via external resistor divider.
RESET functionality integrates a comparator monitoring VOUT against 87.5% of nominal output, with TIMEOUT pin allowing capacitor-adjustable delay beyond the 60µs default. ENABLE accepts up to +42V logic-high signals and includes internal 0.25µA pulldown for fail-safe shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 50mA maximum - sufficient for microcontroller core rails and sensor biasing in space-constrained modules |
| Quiescent Current | 10µA typical at no load - enables >10-year battery standby life in always-on automotive telematics |
| Input Voltage Range | +3.5V to +36V continuous, +42V transient tolerant - survives ISO 7637-2 pulse 5a load dump without external clamping |
| Output Voltage Options | +3.3V or +5V fixed (selected by SETOV pin), or +0.6V to +11V adjustable - supports legacy 5V MCU and modern 3.3V SoC domains |
| RESET Threshold | 87.5% of VOUT with 5% hysteresis - ensures reliable microprocessor reset during brown-out recovery without chatter |
| Dropout Voltage | 130mV typical at 50mA and +150°C - maintains regulation during cold-crank down to 3.5V input for 3.3V output |
| Thermal Shutdown | Activates at +170°C with +20°C hysteresis - protects device during sustained short-circuit or PCB thermal overload |
Pinout & Package
MAX25210ATAD8/V+ uses an 8-pin TDFN-EP (3mm × 3mm) package with exposed thermal pad for enhanced heat dissipation in automotive under-hood environments. The package meets AEC-Q100 Grade 0 qualification and supports reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | High-voltage input rail | Bypassed with ≥1µF ceramic capacitor; withstands +42V transients and powers internal LDO circuitry |
| 2 ENABLE | Active-high enable control | Logic-level input with +42V tolerance; internal 0.25µA pulldown ensures safe shutdown when unconnected |
| 3 SET | Feedback network selector | GND = fixed-output mode; IN or >2.4V = adjustable mode using external resistive divider |
| 4 RESET | Open-drain active-low reset signal | Asserts low during undervoltage, thermal shutdown, or ENABLE deactivation; requires external pull-up ≥1.5V |
| 5 TIMEOUT | Reset timeout period adjust | Capacitor-to-GND extends default 60µs delay; 1.25ms/nF scaling enables µC-compatible reset timing |
| 6 SETOV | Output voltage selection node | GND = 3.3V fixed; OUT = 5V fixed; external divider = adjustable output (0.6V–11V) |
| 7 GND | Power and signal reference | Connected to exposed thermal pad; must be tied to system ground plane for thermal and EMI performance |
| 8 OUT | Regulated output rail | Stable with ≥2.2µF ceramic capacitor; supplies downstream logic, sensors, or analog circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 10µA typical at no load - reduces parasitic drain on 12V vehicle battery during extended parking |
| Automotive transient robustness | +42V input tolerance and load-dump survival - eliminates need for external TVS diodes in ECU front-end design |
| Integrated RESET generator | 87.5% VOUT threshold with adjustable timeout - replaces discrete reset IC and saves board area in compact modules |
| Thermal and short-circuit protection | +170°C shutdown with +20°C hysteresis and 88mA short-circuit limit - prevents catastrophic failure during wiring faults |
| Flexible output configuration | Single device supports 3.3V, 5V, or programmable 0.6V–11V outputs - simplifies BOM management across platform variants |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, low-quiescent-current linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX25210ATAB8/V+ | 200mA output current, same 87.5% RESET threshold and TDFN-EP package | Supports higher-current loads such as multi-channel ADCs or CAN FD transceivers | Select when system load exceeds 50mA but board space and thermal budget allow same footprint |
| TLV73350PDBVR | 500mA output, 45µA IQ, +1.7V to +5.5V input, no RESET or automotive qualification | Limited to low-voltage, non-automotive applications like industrial IoT gateways | Choose only for cost-sensitive, non-automotive designs where 42V tolerance and AEC-Q100 are unnecessary |
Compared with MAX25210ATAD8/V+, MAX25210ATAB8/V+ offers higher drive capability in identical packaging while TLV73350PDBVR trades automotive robustness for lower cost and wider input range in non-qualified applications - neither is pin-compatible, requiring layout revision.

FAQ
What is the guaranteed output current capability of the MAX25210ATAD8/V+?
The MAX25210ATAD8/V+ is specified for 50mA maximum continuous output current, with short-circuit current limit of 58mA to 88mA (typical). This rating is validated across -40°C to +125°C ambient and supports stable operation into capacitive loads up to 22µF when paired with appropriate output capacitance and PCB layout.
Does the MAX25210ATAD8/V+ support both fixed and adjustable output voltages?
Yes, the MAX25210ATAD8/V+ supports both configurations: connect SETOV to GND for +3.3V fixed output, to OUT for +5V fixed output, or to an external resistive divider between OUT and GND for adjustable output from +0.6V to +11V. The SET pin selects mode - GND for fixed, IN or >2.4V for adjustable.
What is the RESET timeout behavior of the MAX25210ATAD8/V+?
The MAX25210ATAD8/V+ provides a default 60µs RESET timeout after VOUT exceeds its 87.5% threshold. Connecting a capacitor from TIMEOUT to GND extends this period linearly at 1.25ms/nF scaling - e.g., a 10nF capacitor yields ~12.5ms delay - enabling compatibility with diverse microprocessor reset timing requirements.
How does the MAX25210ATAD8/V+ handle thermal overload conditions?
When junction temperature reaches +170°C, the MAX25210ATAD8/V+ activates thermal shutdown, turning off the pass transistor. After die temperature drops by +20°C (to +150°C), it automatically restarts. This hysteresis prevents oscillation and protects the device during sustained overload, though continuous operation above +150°C junction is not recommended.
Is the MAX25210ATAD8/V+ qualified for automotive applications?
Yes, the MAX25210ATAD8/V+ is AEC-Q100 qualified for Grade 0 (-40°C to +125°C ambient), featuring +42V input transient tolerance, integrated short-circuit and thermal protection, and operation through cold-crank (down to +3.5V input). Its TDFN-EP package is optimized for thermal performance in automotive under-hood environments.
