Product details
Overview
MAX16910EATA8/V+ from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA at fixed +3.3V output with 20µA no-load supply current, 280mV dropout at 200mA, and +45V input transient tolerance-designed for battery-powered automotive ECUs requiring stable low-power operation during cold-crank and load-dump conditions.
For engineers reviewing the MAX16910EATA8/V+ datasheet, MAX16910EATA8/V+ pinout, MAX16910EATA8/V+ application, or MAX16910EATA8/V+ equivalent, key selection criteria include its 87.5% reset threshold, TDFN-EP (3mm × 3mm) package with exposed pad, -40°C to +125°C operating range, and compatibility with 4.7µF ceramic output capacitance for space-constrained automotive modules.
Technical Context
The MAX16910EATA8/V+ implements a BiCMOS DMOS linear regulation architecture with internal feedback network configured for +3.3V fixed output via SET = GND and SETOV = GND. Its RESET output is open-drain, active-low, with factory-trimmed 87.5% threshold and 60µs default timeout-extendable via TIMEOUT pin capacitor.
Thermal protection activates at +180°C junction temperature with +25°C hysteresis, and short-circuit current limiting holds output at ~330mA. ENABLE is active-high with 45V absolute max rating and internal 0.65µA pulldown, enabling direct connection to battery rail for always-on operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | +3.3V fixed (±2% over temp/load), set by internal resistor divider with SET = GND and SETOV = GND |
| Quiescent current | 20µA at no load-enables >1-year battery standby in always-on automotive modules |
| Shutdown current | 1.6µA-reduces parasitic drain during vehicle sleep mode |
| Input voltage range | +3.5V to +30V continuous, +45V transient tolerant-survives ISO 7637-2 load-dump pulses |
| Dropout voltage | 280mV at 200mA-supports regulation down to 3.58V input for +3.3V output |
| RESET threshold | 87.5% of VOUT (±2.5%)-asserts low when output falls below 2.89V, holds for min. 30µs |
| Operating temperature | -40°C to +125°C ambient-qualified per AEC-Q100 Grade 1 for under-hood use |
Pinout & Package
MAX16910EATA8/V+ is housed in an 8-pin thermally enhanced TDFN-EP package (3mm × 3mm, 0.75mm height) with exposed pad connected internally to GND. The exposed pad must be soldered to PCB ground plane for thermal performance (θJA = 41°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator input | Battery rail input; requires ≥1µF low-ESR ceramic bypass to GND; withstands +45V transients |
| 2 ENABLE | Active-high enable | Drives regulator ON/OFF; internal 0.65µA pulldown ensures shutdown if left floating |
| 3 SET | Feedback mode selector | GND selects fixed-output mode (+3.3V or +5V); high-voltage enables adjustable mode |
| 4 RESET | Open-drain reset output | Asserts low on undervoltage, thermal shutdown, or disable; requires external pullup |
| 5 TIMEOUT | Reset timeout adjust | Capacitor to GND extends 60µs default delay; 1nF yields ~1.25ms timeout |
| 6 SETOV | Output voltage selector | GND configures +3.3V fixed output; OUT configures +5V; resistive divider enables adjustable mode |
| 7 GND | Power ground | Main return path; connects to exposed pad for thermal conduction |
| 8 OUT | Regulated output | +3.3V output; requires ≥4.7µF low-ESR ceramic capacitor to GND for stability |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20µA no-load operation meets automotive module requirements for <100µA system standby current |
| Load-dump robustness | +45V input transient tolerance enables direct connection to 12V/24V battery without external TVS |
| Integrated RESET function | Factory-trimmed 87.5% threshold and programmable timeout eliminate need for discrete reset IC |
| Thermal & short-circuit protection | +180°C shutdown with +25°C hysteresis and 330mA current limit ensure fault resilience in sealed enclosures |
| Fixed +3.3V output configuration | SET/GND + SETOV/GND setup provides precise, stable 3.3V for MCU core logic without external components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16910EATA9/V+ | Same package and specs, but 92.5% RESET threshold (vs. 87.5%); identical pinout and electrical behavior otherwise | Suitable where higher reset release point is required to avoid false resets during slow VOUT ramp-up | Select MAX16910EATA9/V+ only if system requires earlier reset assertion during falling VOUT |
| TLE4275G | 5V fixed output only; 30µA quiescent current; no adjustable RESET timeout; SO-8 package (no EP) | Lacks programmable reset delay and 3.3V option; lower thermal performance (θJA = 70°C/W) | Choose TLE4275G only for legacy 5V-only designs where footprint compatibility with SO-8 is mandatory |
Compared with MAX16910EATA9/V+, the MAX16910EATA8/V+ offers earlier reset assertion (87.5% vs. 92.5%), better suited for systems sensitive to marginal VOUT dips; versus TLE4275G, it delivers lower quiescent current, 3.3V output, and superior thermal management via TDFN-EP package.

FAQ
What is the exact output voltage tolerance of MAX16910EATA8/V+ over temperature and load?
The MAX16910EATA8/V+ delivers +3.3V output with ±2% tolerance across -40°C to +125°C ambient temperature and 1mA to 200mA load current, as specified in the Electrical Characteristics table for VOUT33 parameter under VIN = 4.8V to 30V conditions.
How does the RESET function behave during ENABLE deactivation in MAX16910EATA8/V+?
When ENABLE is pulled low, the MAX16910EATA8/V+ enters shutdown mode and asserts RESET low immediately. RESET remains low throughout shutdown and for 60µs after ENABLE returns high and VOUT exceeds the 87.5% threshold, ensuring reliable microcontroller reset sequencing.
Can MAX16910EATA8/V+ be used with a 2.2µF output capacitor instead of the recommended 4.7µF?
No-MAX16910EATA8/V+ requires a minimum 4.7µF low-ESR ceramic capacitor on the OUT pin for guaranteed stability across -40°C to +125°C. Using 2.2µF may cause oscillation or poor transient response, especially under load steps or temperature extremes.
What is the maximum allowable input voltage for continuous operation of MAX16910EATA8/V+?
The MAX16910EATA8/V+ supports continuous operation up to +30V input voltage. It tolerates +45V transients for ≤400ms per ISO 7637-2 Pulse 5a, but sustained voltage above +30V risks exceeding absolute maximum ratings and thermal limits.
Does MAX16910EATA8/V+ require an external resistor divider to set its +3.3V output?
No-MAX16910EATA8/V+ is factory-configured for +3.3V fixed output. Setting SET = GND and SETOV = GND engages the internal feedback network; no external resistors are needed. External dividers are only required for adjustable output voltages between +1.5V and +11V.
