Product details
Overview
The MAX16910CATA9+T from Analog Devices is an automotive-grade, ultra-low quiescent current linear regulator delivering up to 200mA output with only 20µA no-load supply current and 1.6µA shutdown current. It operates from +3.5V to +30V input, withstands +45V transients, and provides fixed +5V output (92.5% RESET threshold) in a thermally enhanced 3mm × 3mm TDFN-EP package. It serves as a primary power source for microcontrollers and sensors in automotive body control modules.
For engineers reviewing the MAX16910CATA9+T datasheet, MAX16910CATA9+T pinout, MAX16910CATA9+T application, or MAX16910CATA9+T equivalent, this page delivers verified electrical parameters, thermal performance data, RESET timing behavior, fixed-output configuration details, and automotive qualification evidence - all specific to the MAX16910CATA9+T variant with 92.5% reset threshold and TDFN packaging.
Technical Context
The MAX16910CATA9+T implements a high-voltage BiCMOS DMOS linear regulator architecture with integrated thermal shutdown (+180°C trip, +25°C hysteresis) and short-circuit protection (330mA typ). Its feedback network is configured via SET and SETOV pins to select between +3.3V, +5V fixed outputs or adjustable 1.5V–11V operation using an external resistive divider.
It features an open-drain, active-low RESET output with factory-trimmed 92.5% VOUT threshold and 60µs default timeout (extendable via TIMEOUT capacitor), plus a high-voltage ENABLE input rated to +45V with internal 0.65µA pulldown - enabling direct connection to battery rails without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +3.5V to +30V continuous; +45V transient tolerant - supports cold-crank and load-dump conditions in 12V/24V automotive systems. |
| Quiescent Current | 20µA at no load - enables >10-year battery life in always-on vehicle modules (e.g., telematics, alarm systems). |
| Output Current | 200mA max - sufficient to power MCU cores, CAN transceivers, and analog front-ends without external pass devices. |
| Dropout Voltage | 280mV at 200mA - maintains regulation down to VIN = VOUT + 0.28V, critical during low-battery cranking. |
| RESET Threshold | 92.5% of VOUT (±2.5%) - ensures deterministic microcontroller reset before brownout, validated across -40°C to +125°C. |
| Operating Temperature | -40°C to +125°C ambient - qualified per AEC-Q100 Grade 1 for under-hood and cabin applications. |
| Package | 8-pin TDFN-EP (3mm × 3mm) with exposed pad - θJA = 41°C/W enables compact layout with minimal heatsinking. |
Pinout & Package
MAX16910CATA9+T uses an 8-pin thermally enhanced TDFN-EP package (3mm × 3mm) with exposed pad internally connected to GND. The exposed pad must be soldered to a PCB ground plane for thermal management and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator Input | Battery rail connection; requires ≥1µF low-ESR ceramic bypass to GND for stability under load-dump transients. |
| 2 ENABLE | Active-High Enable | Drives regulator ON/OFF; +45V tolerant, internally pulled down - allows direct battery tie or microcontroller GPIO control. |
| 3 SET | Feedback Mode Selector | GND = fixed output mode; IN or >2.4V = adjustable mode - configures internal vs. external feedback path. |
| 4 RESET | Open-Drain Reset Output | Asserts low when VOUT < 92.5% threshold; remains low for ≥60µs after recovery - eliminates need for discrete reset IC. |
| 5 TIMEOUT | Reset Timeout Adjust | Connect capacitor to GND to extend RESET assertion time beyond 60µs; unconnected = default delay. |
| 6 SETOV | Output-Voltage Selector | Connected to OUT = +5V fixed; to GND = +3.3V fixed; to resistive divider = adjustable 1.5V–11V output. |
| 7 GND | Power Ground | Reference for all signals; must be tied to exposed pad and system ground plane for thermal and noise integrity. |
| 8 OUT | Regulated Output | Delivers stable +5V; requires ≥4.7µF low-ESR ceramic capacitor to GND for stability across temperature and load. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20µA no-load / 1.6µA shutdown - meets ISO 16750-2 "parking mode" current budget for automotive ECUs. |
| Integrated RESET generator | Factory-trimmed 92.5% VOUT threshold with adjustable timeout - replaces discrete supervisor IC and saves board space. |
| Load-dump robustness | +45V input transient tolerance - survives ISO 7637-2 Pulse 5a without external TVS diode. |
| Thermal & short-circuit protection | +180°C thermal shutdown with +25°C hysteresis and 330mA current limit - prevents damage during sustained overload. |
| Fixed +5V output configuration | Optimized for MCU core logic and CAN PHY power domains - eliminates external resistor network for simplified BOM. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16910CATA8+T | Same package and specs, but 87.5% RESET threshold instead of 92.5% - tighter margin for early reset assertion. | Suitable where earlier reset initiation is required before deeper brownout, e.g., safety-critical watchdog supervision. | Select MAX16910CATA8+T if system requires reset at lower VOUT deviation; otherwise MAX16910CATA9+T provides wider noise margin. |
| TLE4275G | 5V fixed LDO with 30µA IQ, +40V transient rating, no integrated RESET - requires external supervisor IC. | Used in legacy automotive designs where RESET timing is handled separately; lacks adjustable timeout and 92.5% precision threshold. | Choose TLE4275G only if existing design already includes discrete reset circuitry and higher IQ is acceptable. |
Compared with MAX16910CATA8+T and TLE4275G, the MAX16910CATA9+T offers superior brownout margin via its 92.5% RESET threshold, eliminates external reset components, and achieves the lowest quiescent current in its class - making it optimal for next-generation low-power automotive modules.

FAQ
What is the RESET threshold voltage for MAX16910CATA9+T?
The MAX16910CATA9+T has a factory-trimmed RESET threshold of 92.5% of the output voltage, with ±2.5% tolerance over temperature. For a +5V output, this corresponds to 4.625V minimum, ensuring reliable microcontroller reset before functional failure. This value is confirmed in the Electrical Characteristics table and applies specifically to the "9" suffix variant.
Does MAX16910CATA9+T support adjustable output voltage?
Yes, MAX16910CATA9+T supports adjustable output voltage from +1.5V to +11V by connecting the SET pin to IN (or >2.4V) and using an external resistive divider between OUT and SETOV. However, the "CATA9+T" ordering code specifies fixed +5V output configuration - adjustable mode requires proper external component selection and layout per the datasheet's Detailed Description section.
What package type does MAX16910CATA9+T use?
MAX16910CATA9+T uses an 8-pin TDFN-EP (Thin Dual Flat No-lead with Exposed Pad) package measuring 3mm × 3mm. The exposed pad is internally connected to GND and must be soldered to the PCB ground plane to achieve the specified θJA = 41°C/W thermal performance and ensure EMI suppression.
How is the RESET timeout period set on MAX16910CATA9+T?
The MAX16910CATA9+T provides a default RESET timeout of 60µs when the TIMEOUT pin is left unconnected. To extend the delay, connect a low-leakage capacitor (≥100pF, ceramic recommended) from TIMEOUT to GND. The timeout scales linearly: CTIMEOUT (nF) = 0.8 × ITO (μA) × TTIMEOUT (ms), where ITO = 1.0μA typical.
Is MAX16910CATA9+T qualified for automotive applications?
Yes, MAX16910CATA9+T is AEC-Q100 qualified (Grade 1, -40°C to +125°C ambient) and designed for automotive use. It features +45V input transient tolerance, thermal shutdown with hysteresis, short-circuit protection, and operation through cold-crank conditions - all validated per ISO 16750 and ISO 7637 standards.
