Product details
Overview
The MAX16910CASA8+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 supports fixed +3.3V or +5V outputs (this variant uses 87.5% reset threshold). It is deployed in battery-powered automotive ECUs requiring cold-crank operation and load-dump resilience.
For engineers reviewing the MAX16910CASA8+T datasheet, MAX16910CASA8+T pinout, MAX16910CASA8+T application, or MAX16910CASA8+T equivalent, key selection criteria include its 280mV dropout at 200mA, open-drain RESET with adjustable timeout, thermal/short-circuit protection, and SO-EP package compatibility with industrial temperature range (-40°C to +125°C).
Technical Context
This device implements a high-voltage BiCMOS DMOS linear regulator architecture with integrated feedback multiplexing for fixed/adjustable output modes. Its ENABLE input tolerates +45V and features internal 0.65µA pulldown, enabling direct connection to battery rails without external biasing.
The RESET circuit uses dual fixed thresholds (87.5% or 92.5% of VOUT) with 60µs default timeout extendable via TIMEOUT pin capacitor. Thermal shutdown activates at +180°C with +25°C hysteresis, and short-circuit current limit is typ. 330mA - both protecting under fault conditions while maintaining automotive reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +3.5V to +30V continuous; +45V transient tolerant - survives automotive load-dump events without external clamping. |
| Quiescent Current | 20µA at no load - enables >1-year battery life in always-on vehicle modules. |
| Shutdown Current | 1.6µA - meets stringent ISO 16750-2 sleep-mode requirements. |
| Output Current | 200mA max - sufficient for MCU, CAN transceiver, and sensor power in compact ECUs. |
| Dropout Voltage | 280mV at 200mA - sustains regulation during cold-crank down to ~4.5V battery voltage. |
| RESET Threshold | 87.5% of VOUT - ensures reliable microcontroller reset before brownout in 3.3V/5V systems. |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive placement per AEC-Q100. |
Pinout & Package
MAX16910CASA8+T is housed in an 8-pin SO-EP (5mm × 4mm) package with exposed thermal pad connected internally to GND. The package provides 53°C/W junction-to-ambient thermal resistance and supports reflow soldering at +260°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator input | Battery rail connection; requires ≥1µF low-ESR ceramic bypass to GND for stability and transient immunity. |
| 2 ENABLE | Active-high enable | Drives regulator ON/OFF; +45V tolerant and internally pulled down - eliminates need for external pull-down resistor. |
| 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 on undervoltage, thermal shutdown, or ENABLE deactivation - interfaces directly with µC reset pin. |
| 5 TIMEOUT | Reset timeout adjust | Capacitor-to-GND sets delay beyond 60µs default - enables precise reset timing for diverse microcontrollers. |
| 6 SETOV | Output voltage selector | GND = 3.3V fixed; OUT = 5V fixed; external divider = 1.5V–11V adjustable - selects feedback reference point. |
| 7 GND | Power ground | Reference for all signals; must be connected to PCB ground plane with multiple vias for thermal and noise performance. |
| 8 OUT | Regulated output | Delivers stable 3.3V or 5V; requires ≥4.7µF low-ESR ceramic capacitor to GND for stability across -40°C to +125°C. |
Key Features
| Feature | Design Value |
|---|---|

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 | TDFN-EP (3mm × 3mm) package vs. SO-EP; θJA = 41°C/W vs. 53°C/W - lower thermal resistance enables higher ambient operation. | Better suited for space-constrained modules where PCB area is premium; same electrical specs and pinout. | Select when thermal performance or footprint size outweighs assembly complexity of fine-pitch TDFN. |
| TPS7B6750QDDARQ1 | 5V fixed output only; 35µA IQ; 400mA output; 300mV dropout at 250mA - higher current but higher quiescent draw. | Lacks adjustable output and dual-reset-threshold options; optimized for cost-sensitive, high-current automotive loads. | Choose when >200mA output is required and 3.3V/adjustable output is unnecessary; verify RESET timing compatibility. |
Compared with MAX16910CASA8+T, the MAX16910CATA8+T offers superior thermal dissipation in a smaller footprint, while the TPS7B6750QDDARQ1 trades ultra-low IQ for higher output current and simplified fixed-voltage design - making each suitable for distinct ECU power architecture priorities.

FAQ
What output voltage options does the MAX16910CASA8+T support?
The MAX16910CASA8+T supports fixed +3.3V or +5V outputs via SETOV pin configuration (GND or OUT), and adjustable 1.5V–11V outputs using an external resistive divider. This variant is factory-configured for 87.5% RESET threshold and shipped in SO-EP package - no internal trimming required for standard fixed outputs.
How does the RESET function operate on the MAX16910CASA8+T?
The MAX16910CASA8+T features an open-drain, active-low RESET output that asserts low when VOUT falls below 87.5% of nominal voltage, during ENABLE deactivation, or under thermal shutdown. After VOUT recovers, RESET remains low for a fixed 60µs timeout - extendable with a capacitor on the TIMEOUT pin - ensuring reliable microcontroller initialization.
What is the thermal performance of the MAX16910CASA8+T in its SO-EP package?
The MAX16910CASA8+T in 8-pin SO-EP package has a junction-to-ambient thermal resistance (θJA) of 53°C/W and junction-to-case (θJC) of 7°C/W. At +70°C ambient, it dissipates up to 1.861W continuously; derating is 23.3mW/°C above +70°C. The exposed pad must be soldered to a ground plane for optimal thermal conduction.
Can the MAX16910CASA8+T operate during automotive cold-crank conditions?
Yes - the MAX16910CASA8+T maintains regulation down to +3.5V input and exhibits only 280mV dropout at 200mA load, enabling stable 3.3V/5V output even when battery voltage dips to ~4.5V during engine cranking. Its wide +3.5V to +30V input range and +45V transient tolerance make it ideal for 12V automotive systems.
What protection features are integrated into the MAX16910CASA8+T?
The MAX16910CASA8+T integrates thermal shutdown (trip at +180°C, +25°C hysteresis), short-circuit current limiting (typ. 330mA), and input overvoltage tolerance (+45V). ENABLE is +45V tolerant and internally pulldown-biased, eliminating external components. These features collectively ensure robust operation in automotive fault environments without external protection circuitry.
