Product details
Overview
MAX16910CATA8+T from Analog Devices is an automotive-qualified, 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 (transient-tolerant to +45V), supports fixed +3.3V/+5V or adjustable +1.5V to +11V outputs, and features open-drain active-low RESET with 87.5% threshold-designed for battery-powered automotive ECUs requiring cold-crank operation and load-dump resilience.
For engineers reviewing the MAX16910CATA8+T datasheet, MAX16910CATA8+T pinout, MAX16910CATA8+T application, or MAX16910CATA8+T equivalent, key selection criteria include its 280mV dropout at 200mA, -40°C to +125°C operating range, TDFN-EP 3mm × 3mm package with exposed pad, RESET timeout adjustability via TIMEOUT pin, and integrated thermal/short-circuit protection.
Technical Context
The MAX16910CATA8+T implements a high-voltage BiCMOS DMOS linear regulator architecture with internal feedback network selection (via SET/SETOV) enabling fixed or adjustable output modes. Its control logic integrates thermal shutdown (+180°C trip, +25°C hysteresis), 330mA short-circuit current limiting, and precision bandgap-based RESET monitoring referenced to VOUT.
RESET assertion is triggered by VOUT falling below 87.5% of nominal output (confirmed for MAX16910CATA8+T per Ordering Guide), with a default 60µs timeout extendable via external capacitor on TIMEOUT pin; ENABLE is active-high with 45V tolerance and internal 0.65µA pulldown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +3.5V to +30V continuous; +45V transient tolerant-enables direct connection to 12V/24V automotive batteries under load-dump conditions. |
| Quiescent Current | 20µA at no load-meets <100µA module standby requirements for always-on automotive modules. |
| Output Current | Up to 200mA continuous-supports microcontroller cores, CAN transceivers, and sensor interfaces in compact ECUs. |
| Dropout Voltage | 280mV at 200mA-ensures regulation during cold-crank (as low as ~6V battery) with +5V output. |
| RESET Threshold | 87.5% of VOUT (fixed)-guarantees deterministic microcontroller reset before brownout in safety-critical systems. |
| Operating Temperature | -40°C to +125°C ambient-qualified for under-hood automotive placement per AEC-Q100 stress test profiles. |
| Package | 8-pin TDFN-EP (3mm × 3mm) with exposed thermal pad-provides 41°C/W θJA for high-power-density layouts. |
Pinout & Package
MAX16910CATA8+T is housed in an 8-pin thermally enhanced TDFN-EP package (3mm × 3mm, 0.75mm height) with exposed pad internally connected to GND. The pad must be soldered to PCB ground plane for thermal performance and EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator input | Bypass with ≥1µF low-ESR ceramic capacitor; withstands +45V transients-directly interfaces with unregulated vehicle battery rail. |
| 2 ENABLE | Active-high enable | Internally pulled down (0.65µA); 45V tolerant-allows direct connection to IN for always-on operation or microcontroller GPIO control. |
| 3 SET | Feedback mode selector | GND = fixed output mode; >2.4V = adjustable mode-configures internal vs. external resistive divider feedback path. |
| 4 RESET | Open-drain active-low reset | Asserts low during VOUT undervoltage, ENABLE low, or thermal shutdown-eliminates need for discrete reset IC in MCU power sequencing. |
| 5 TIMEOUT | Reset timeout adjustment | Unconnected = 60µs default; capacitor to GND extends delay-enables precise match to processor reset timing requirements. |
| 6 SETOV | Output voltage selector | GND = +3.3V fixed; OUT = +5V fixed; external divider = adjustable 1.5V–11V-defines regulated output setpoint without external op-amp. |
| 7 GND | Power ground | Reference for all analog circuitry; connects to exposed pad-requires low-impedance PCB ground plane for stability and thermal dissipation. |
| 8 OUT | Regulated output | Stable with ≥4.7µF low-ESR ceramic capacitor-powers noise-sensitive analog/digital loads with <12mV load regulation over full current range. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20µA at no load enables >1-year battery life in always-on telematics modules powered by 12V lead-acid or LiFePO₄ cells. |
| Automotive-grade RESET function | 87.5% VOUT threshold with 60µs minimum timeout ensures reliable microcontroller initialization across temperature and line transients. |
| Robust input transient handling | +45V tolerance and load-dump survival allow direct integration into 12V/24V automotive power domains without external TVS clamping. |
| Thermal and short-circuit protection | +180°C thermal shutdown with +25°C hysteresis and 330mA current limit prevent damage during sustained overload or PCB thermal runaway. |
| Flexible output configuration | Single device supports +3.3V, +5V fixed, or +1.5V–+11V adjustable outputs-reduces BOM count across multiple ECU variants. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16910CATA9+T | Identical package and specs except RESET threshold is 92.5% of VOUT instead of 87.5%. | Suitable where tighter reset margin is required to prevent premature release during slow-rising VOUT or noisy supply conditions. | Select MAX16910CATA9+T when system requires earlier reset assertion during power-up or higher immunity to ripple-induced false releases. |
| TPS7B8250QDGNRQ1 | Lower IQ (15µA), same 200mA output, but fixed 5V only; RESET threshold is 92% with 200ms min timeout (non-adjustable). | Lacks adjustable output and TIMEOUT pin flexibility; optimized for cost-sensitive, single-rail automotive modules. | Choose TPS7B8250QDGNRQ1 for simplified 5V-only designs where extended RESET timeout and output configurability are unnecessary. |
Compared with MAX16910CATA9+T, the MAX16910CATA8+T provides earlier reset release due to its 87.5% threshold-critical for fast-boot MCUs-while TPS7B8250QDGNRQ1 trades configurability for lower IQ and AEC-Q100 Grade 0 qualification, making it suitable for less thermally demanding locations.

FAQ
What is the RESET threshold voltage for MAX16910CATA8+T?
The MAX16910CATA8+T has a fixed RESET threshold of 87.5% of the nominal output voltage-e.g., 4.375V for a +5V output or 2.8875V for a +3.3V output. This value is confirmed in the Ordering Information table and Electrical Characteristics section of the datasheet, and applies across the full -40°C to +125°C operating range.
Does MAX16910CATA8+T support adjustable output voltage?
Yes, MAX16910CATA8+T supports adjustable output from +1.5V to +11V using an external resistive divider between OUT and SETOV pins. To enable this mode, connect SET to IN (or >2.4V), then configure R1/R2 such that VOUT = 1.25V × (1 + R1/R2), with R2 ≤ 100kΩ for accuracy and stability.
What package type and thermal characteristics does MAX16910CATA8+T use?
MAX16910CATA8+T uses an 8-pin TDFN-EP package (3mm × 3mm) with exposed thermal pad connected to GND. Its junction-to-ambient thermal resistance is 41°C/W on a multilayer board, and junction-to-case is 8°C/W-enabling 609mW max power dissipation at +125°C ambient per derating curves in the datasheet.
How is the RESET timeout period configured on MAX16910CATA8+T?
The RESET timeout on MAX16910CATA8+T defaults to 60µs when the TIMEOUT pin is left unconnected. To extend it, connect a low-leakage capacitor (≥100pF, ceramic recommended) from TIMEOUT to GND; timeout scales linearly as CTIMEOUT (nF) × 1.25 ms/nF, e.g., 8nF yields ~10ms delay.
Is MAX16910CATA8+T qualified for automotive applications?
Yes, MAX16910CATA8+T is automotive-qualified per AEC-Q100 with operating temperature range -40°C to +125°C, +45V input transient tolerance, and built-in thermal shutdown (+180°C) and short-circuit protection-meeting requirements for under-hood and safety-critical ECU deployments.
