Product details
Overview
MAX16910EASA9/V+ from Analog Devices is an automotive-grade, ultra-low quiescent current linear regulator delivering up to 200mA at fixed +5V output with 92.5% reset threshold, 20µA no-load supply current, and +45V input transient tolerance - deployed in battery-powered vehicle control modules requiring cold-crank operation and load-dump resilience.
For engineers reviewing the MAX16910EASA9/V+ datasheet, MAX16910EASA9/V+ pinout, MAX16910EASA9/V+ application, or MAX16910EASA9/V+ equivalent, key selection criteria include its 92.5% RESET threshold accuracy, 280mV dropout at 200mA, -40°C to +125°C operating range, TDFN/SO package compatibility, and fixed +5V output configuration validated for automotive power rail conditioning.
Technical Context
The MAX16910EASA9/V+ implements a high-voltage BiCMOS DMOS linear regulation architecture with integrated thermal shutdown (+180°C trip), short-circuit protection (330mA limit), and active-high ENABLE input tolerant to +45V. Its RESET circuit uses internal voltage comparators referenced to 92.5% of VOUT, with fixed 60µs timeout extendable via TIMEOUT pin capacitor.
Output voltage is set by SETOV pin state (connected to OUT for +5V mode) and SET pin grounded; the device operates in fixed-output mode without external resistive divider. The 8-pin SO-EP package provides 53°C/W θJA and requires exposed pad soldering to PCB ground for thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +3.5V to +30V continuous, +45V transient tolerant - supports 12V/24V automotive battery rails including load-dump events. |
| Quiescent Current | 20µA at no load - enables >10-year battery standby in always-on vehicle modules. |
| Output Current | 200mA maximum - sufficient for MCU core logic, CAN transceivers, and sensor interfaces. |
| Dropout Voltage | 280mV at 200mA - maintains regulation during cold-crank down to ~4.7V input for +5V output. |
| RESET Threshold | 92.5% of VOUT (±2.5%) - ensures deterministic microcontroller reset before brownout. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood and transmission-control unit environments. |
| Package | 8-pin SO-EP (5mm × 4mm) with exposed thermal pad - enables 1.861W max power dissipation at +70°C ambient. |
Pinout & Package
MAX16910EASA9/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 direct soldering to PCB ground plane for thermal conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator input | Bypassed with ≥1µF ceramic capacitor; accepts +3.5V–+30V supply and withstands +45V transients. |
| 2 ENABLE | Active-high enable | Logic-high (>2.4V) enables regulation; internally pulled down (0.65µA) for default shutdown; +45V tolerant. |
| 3 SET | Mode selector | GND connection configures fixed-output mode; floating or high disables internal feedback for adjustable operation. |
| 4 RESET | Open-drain active-low reset | Asserts low when VOUT drops below 92.5% threshold or ENABLE is low; sinks 0.5mA at ≤0.4V. |
| 5 TIMEOUT | Reset delay timing | Unconnected yields 60µs default timeout; external capacitor extends delay per C = 0.8 × ITO × tRP. |
| 6 SETOV | Output voltage selector | Connected to OUT for +5V fixed output; sets internal 1.25V reference point for feedback loop. |
| 7 GND | Power ground | Reference for all signals; must be tied to exposed pad and system ground plane. |
| 8 OUT | Regulated output | Delivers stable +5V; bypassed with ≥4.7µF low-ESR ceramic capacitor for stability across temperature. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20µA at no load - reduces parasitic drain in always-on automotive modules to <175µAh/year. |
| Automotive-grade RESET function | 92.5% VOUT threshold with 60µs minimum assertion time - eliminates need for discrete reset IC in ECU designs. |
| Load-dump resilient input stage | +45V transient tolerance on IN and ENABLE pins - sustains operation during ISO 7637-2 Pulse 5a events without external clamping. |
| Thermal and short-circuit protection | +180°C thermal shutdown with +25°C hysteresis and 330mA current limiting - prevents damage during sustained overload or PCB fault conditions. |
| Fixed +5V output configuration | No external resistor divider required - simplifies BOM and layout for dedicated 5V rail generation in infotainment and ADAS subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16910EASA8/V+ | Same SO-EP package and specs, but 87.5% RESET threshold instead of 92.5%. | Suitable where earlier reset assertion is needed during gradual brownout (e.g., battery monitoring systems). | Select MAX16910EASA8/V+ only if system-level reset timing requires lower threshold; otherwise MAX16910EASA9/V+ preferred for tighter VOUT margin. |
| TPS7B8750QKVURQ1 | 5V fixed-output automotive LDO with 35µA IQ, 300mA rating, and 90% RESET threshold; larger 5-pin SOT-223 package. | Higher current capability suits higher-power domains; less space-efficient layout due to SOT-223 footprint. | Choose TPS7B8750QKVURQ1 when >200mA load or different package constraints apply; not drop-in compatible with SO-EP land pattern. |
Compared with MAX16910EASA8/V+, the MAX16910EASA9/V+ offers later reset assertion for improved noise immunity; versus TPS7B8750QKVURQ1, it delivers superior quiescent current and smaller SO-EP footprint but lower output current ceiling.

FAQ
What output voltage does the MAX16910EASA9/V+ deliver?
The MAX16910EASA9/V+ is configured as a fixed +5V output regulator. This is achieved by connecting the SETOV pin to the OUT pin and grounding the SET pin - no external resistive divider is required. Output voltage is specified as 4.9V to 5.1V across 1mA–200mA load and full temperature range (-40°C to +125°C). The MAX16910EASA9/V+ does not support adjustable output in this variant.
How does the RESET function operate on the MAX16910EASA9/V+?
The MAX16910EASA9/V+ features an open-drain, active-low RESET output with a fixed 92.5% threshold of the output voltage. When VOUT falls below this threshold, RESET asserts low immediately. After VOUT recovers above threshold, RESET remains low for a fixed 60µs timeout (extendable with external capacitor on TIMEOUT pin). RESET also asserts during ENABLE deactivation and thermal shutdown.
What package type is used for the MAX16910EASA9/V+?
The MAX16910EASA9/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 the PCB ground plane to achieve specified thermal performance (θJA = 53°C/W). This package differs from the TDFN-EP variant (e.g., MAX16910EATA9/V+) and is not pin-compatible with it.
Does the MAX16910EASA9/V+ support shutdown mode, and what is its current draw?
Yes, the MAX16910EASA9/V+ supports shutdown mode via the active-high ENABLE pin. When ENABLE is pulled low (≤0.4V), the device enters shutdown and draws only 1.6µA typical supply current at +25°C - dropping to ≤3µA across the full -40°C to +125°C temperature range. An internal 0.65µA pulldown ensures reliable shutdown if ENABLE is left floating or driven high-impedance.
Is the MAX16910EASA9/V+ qualified for automotive applications?
Yes, the MAX16910EASA9/V+ is explicitly automotive-qualified, indicated by the "/V+" suffix in its part number. It meets AEC-Q100 stress testing requirements and operates across the full -40°C to +125°C junction temperature range. Its +45V input transient tolerance, thermal shutdown (+180°C), and robust RESET functionality are designed for under-hood and chassis-mounted automotive electronics.
