Analog Devices Inc./Maxim Integrated MAX16910EASA8/V+

Overview

MAX16910EASA8/V+ from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA at fixed +3.3V output, operating from +3.5V to +30V input with +45V transient tolerance, 20µA no-load IQ, and integrated open-drain RESET with 87.5% threshold-designed for battery-powered automotive ECUs requiring cold-crank operation and load-dump resilience.

For engineers reviewing the MAX16910EASA8/V+ datasheet, MAX16910EASA8/V+ pinout, MAX16910EASA8/V+ application, or MAX16910EASA8/V+ equivalent, key selection factors include its 87.5% RESET threshold, SO-EP package thermal performance (θJA = 53°C/W), 280mV dropout at 200mA, -40°C to +125°C automotive temperature range, and compatibility with 4.7µF ceramic output capacitors.

Technical Context

The MAX16910EASA8/V+ implements a BiCMOS DMOS linear regulation architecture with internal feedback network selection via SET and SETOV pins, enabling fixed +3.3V output when SET = GND and SETOV = GND. Its RESET circuitry uses a precision comparator monitoring VOUT against 87.5% of nominal output, latching low for 60µs minimum after recovery.

Thermal protection activates at +180°C junction temperature with +25°C hysteresis, while short-circuit current limiting holds output at ~330mA during fault conditions. ENABLE withstands +45V and features an internal 0.65µA pulldown, supporting direct connection to VIN for always-on operation without external pull-down.

Key Specifications

Pinout & Package

MAX16910EASA8/V+ is housed in an 8-pin SO-EP (small-outline, exposed pad) package measuring 5mm × 4mm, with the exposed pad internally connected to GND and requiring soldering to PCB ground plane for optimal thermal performance (θJC = 7°C/W).

FAQ

What is the RESET threshold voltage for MAX16910EASA8/V+?

The MAX16910EASA8/V+ has a fixed RESET threshold of 87.5% of its nominal output voltage. With a +3.3V output, this corresponds to 2.89V (typical), with ±2.5% variation over temperature and load. The RESET output remains asserted low for a minimum of 60µs after VOUT rises above this threshold, and the timeout period can be extended using an external capacitor on the TIMEOUT pin.

Can MAX16910EASA8/V+ be used in adjustable-output configurations?

No-MAX16910EASA8/V+ is factory-configured for fixed +3.3V output only, as indicated by the "8" suffix and 87.5% RESET threshold variant. To achieve adjustable output (1.5V–11V), a different variant such as MAX16910EASA9/V+ with SET pin driven high and external resistive divider on SETOV is required. The MAX16910EASA8/V+ pinout and internal feedback network are hardwired for 3.3V fixed operation.

What package type does MAX16910EASA8/V+ use, and how should the exposed pad be handled?

MAX16910EASA8/V+ uses an 8-pin SO-EP (small-outline with exposed pad) package measuring 5mm × 4mm. The exposed pad is internally connected to GND and must be soldered to a PCB ground plane using multiple thermal vias to achieve the specified θJA = 53°C/W and ensure reliable operation at full 200mA load in +125°C ambient environments.

How does MAX16910EASA8/V+ behave during automotive load-dump events?

MAX16910EASA8/V+ withstands +45V transients on the IN pin for up to 400ms per ISO 7637-2 Pulse 5a, enabling direct connection to vehicle battery without external TVS diodes. Its internal pass transistor and protection circuitry remain functional throughout the event, maintaining regulated 3.3V output to downstream logic as long as junction temperature stays below +150°C-verified in production testing per AEC-Q100.

Is MAX16910EASA8/V+ compatible with ceramic output capacitors?

Yes-MAX16910EASA8/V+ is optimized for stability with low-ESR ceramic capacitors. A minimum 4.7µF X7R or X5R ceramic capacitor is required on the OUT pin for stable operation across –40°C to +125°C. Larger values (e.g., 10µF–22µF) further improve load-transient response and PSRR, especially in noise-sensitive ADAS or infotainment applications.
