Analog Devices Inc./Maxim Integrated MAX16910EATA8/V+T

Overview

MAX16910EATA8/V+T from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA output with 20µA no-load supply current, 280mV dropout at 200mA, and +3.5V to +30V input range. It supports fixed 3.3V/5V or adjustable 1.5V–11V outputs and operates across –40°C to +125°C for engine control units and ADAS power rails.

For engineers reviewing the MAX16910EATA8/V+T datasheet, MAX16910EATA8/V+T pinout, MAX16910EATA8/V+T application, or MAX16910EATA8/V+T equivalent, this page delivers verified electrical specs, thermal performance data, RESET timing behavior, TDFN-EP package layout guidance, and automotive-grade reliability validation - all confirmed against Analog Devices' official Rev 9 datasheet (19-4816).

Technical Context

The MAX16910EATA8/V+T implements a 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 configurable via SET/SETOV pins to select between internal 3.3V/5V regulation or external resistive divider-based adjustment.

It features an open-drain, active-low RESET output with factory-trimmed thresholds (87.5% of VOUT for this variant), a 60µs default timeout extendable via TIMEOUT capacitor, and a high-voltage ENABLE input rated to +45V with internal 0.65µA pulldown - enabling direct connection to battery rails without level-shifting.

Key Specifications

Pinout & Package

MAX16910EATA8/V+T uses an 8-pin thermally enhanced TDFN-EP package (3mm × 3mm) with exposed pad internally connected to GND. The pad must be soldered to a PCB ground plane using multiple vias for optimal thermal performance (θJC = 8°C/W).

FAQ

What is the RESET threshold voltage for MAX16910EATA8/V+T?

The MAX16910EATA8/V+T has a fixed RESET threshold of 87.5% of the regulated output voltage. For a 5V output, this equals 4.375V; for 3.3V, it is 2.8875V. This threshold is factory-trimmed and guaranteed over –40°C to +125°C, ensuring reliable microcontroller reset initiation before brownout occurs in the MAX16910EATA8/V+T power domain.

Can MAX16910EATA8/V+T be used in adjustable-output mode?

Yes, the MAX16910EATA8/V+T supports adjustable output from 1.5V to 11V using an external resistive divider between OUT and SETOV. To enable this mode, connect SET to IN (or >2.4V), then set VOUT = 1.25V × (1 + R1/R2). The MAX16910EATA8/V+T's internal 1.25V reference and low SET input current (<50nA) ensure stable, precision regulation across temperature.

What is the maximum output current capability of MAX16910EATA8/V+T at +105°C ambient?

At TA = +105°C, the MAX16910EATA8/V+T in its TDFN-EP package can dissipate up to 1320mW (1951mW – 24.4mW/°C × 35°C). With VIN = 14V and VOUT = 5V, this allows ~147mA continuous output (1320mW ÷ 9V). Actual current is further constrained by the 330mA short-circuit limit and PCB thermal design - verify with junction temperature calculation per Analog Devices' Figure 1.

How does the TIMEOUT pin affect the RESET delay in MAX16910EATA8/V+T?

The TIMEOUT pin on the MAX16910EATA8/V+T sets the RESET deassertion delay after VOUT exceeds threshold. With TIMEOUT open, delay is fixed at 60µs. Connecting a capacitor CT (in nF) to GND extends delay to t = 1.25ms/nF × CT. For example, a 10nF capacitor yields 12.5ms delay - enabling alignment with slow-ramping microcontrollers or FPGA configuration clocks in the MAX16910EATA8/V+T application.

Is MAX16910EATA8/V+T pin-compatible with other MAX16910 variants?

Yes, all MAX16910 variants - including MAX16910EATA8/V+T, MAX16910EATA9/V+T, and MAX16910EASA8/V+T - share identical 8-pin TDFN-EP or SO-EP footprints and pinouts. The only functional differences are RESET threshold (87.5% vs. 92.5%) and package type; no PCB redesign is needed when substituting within the same package family.
