Product details
Overview
MAX16910CASA9/V+T from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA at fixed +5V output with 20µA no-load supply current, 280mV dropout at 200mA, and +45V input transient tolerance-designed for battery-powered vehicle ECUs requiring stable low-power bias under cold-crank and load-dump conditions.
For engineers reviewing the MAX16910CASA9/V+T datasheet, MAX16910CASA9/V+T pinout, MAX16910CASA9/V+T application, or MAX16910CASA9/V+T equivalent, this page provides verified functional identity, validated 8-pin SO-EP package mapping, confirmed RESET threshold (92.5% of VOUT), thermal shutdown (+180°C), and real-world design meaning for each key specification-enabling rapid selection against automotive power-rail requirements.
Technical Context
The MAX16910CASA9/V+T implements a high-voltage BiCMOS DMOS linear regulation architecture with integrated active-low open-drain RESET, adjustable timeout via TIMEOUT pin, and tri-mode output configuration (3.3V/5V fixed or 1.5V–11V adjustable). Its ENABLE input withstands +45V and features internal 0.65µA pulldown for reliable shutdown control.
It integrates thermal shutdown (+180°C trip, +25°C hysteresis) and short-circuit protection (330mA typ limit), operates across -40°C to +125°C, and maintains stability with only 4.7µF ceramic output capacitance-eliminating need for external reset ICs in microcontroller-based automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 200mA continuous-supports MCU, CAN transceivers, and sensor interfaces without derating at TA ≤ +85°C. |
| Quiescent Current | 20µA at no load-meets ISO 16750-2 standby current limits for always-on automotive modules. |
| Input Voltage Range | +3.5V to +30V continuous, +45V transient tolerant-survives load-dump pulses per ISO 7637-2 Pulse 5a. |
| Dropout Voltage | 280mV at 200mA-enables regulation down to VIN = 5.28V for +5V output, critical during cold-crank (≤ 6V). |
| RESET Threshold | 92.5% of VOUT (fixed)-ensures deterministic microcontroller reset assertion before brownout in safety-critical systems. |
| Operating Temp | -40°C to +125°C ambient-qualified per AEC-Q100 Grade 1, suitable for engine bay and body control modules. |
| Package | 8-pin SO-EP (5mm × 4mm)-exposed pad thermally connected to PCB ground for 53°C/W θJA, enabling 1861mW max dissipation at +70°C. |
Pinout & Package
MAX16910CASA9/V+T is housed in an 8-pin SO-EP (small-outline, exposed pad) package measuring 5mm × 4mm. The exposed pad (EP) must be soldered to PCB ground for thermal performance and electrical reference; it is internally connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator input | Bypass with ≥1µF low-ESR ceramic; accepts +3.5V–+30V, withstands +45V transients. |
| 2 ENABLE | Active-high enable | Logic-high ≥2.4V enables regulation; internal 0.65µA pulldown ensures safe default-off state. |
| 3 SET | Feedback mode selector | GND = fixed-output mode (3.3V/5V); IN or >2.4V = adjustable mode using external resistor divider. |
| 4 RESET | Open-drain active-low reset | Asserts low when VOUT drops below 92.5% threshold; remains low for 60µs min after recovery. |
| 5 TIMEOUT | Reset timeout adjust | Capacitor to GND extends default 60µs delay; supports µP reset timing compliance (e.g., ARM Cortex-M). |
| 6 SETOV | Output voltage selector | GND = 3.3V fixed; OUT = 5V fixed; external divider = 1.5V–11V adjustable (VSETOV = 1.25V reference). |
| 7 GND | Power ground | Primary return path; EP must be connected to same ground plane for thermal integrity. |
| 8 OUT | Regulated output | Stable +5V (or configured voltage); requires ≥4.7µF low-ESR ceramic capacitor for full-temp stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20µA no-load operation enables >1-year battery life in always-on telematics modules. |
| Integrated RESET with adjustable timeout | Eliminates discrete reset IC; 60µs–10ms programmable delay meets ARM/Infineon µP reset timing specs. |
| Load-dump and cold-crank resilience | +45V transient tolerance and 280mV dropout at 200mA ensure uninterrupted operation during ISO 7637-2 events. |
| Thermal and short-circuit protection | +180°C shutdown with +25°C hysteresis and 330mA current limit prevent damage during sustained overload. |
| Automotive qualification | AEC-Q100 Grade 1 certified (-40°C to +125°C), qualified for ECU, ADAS camera, and gateway applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16910CATA9/V+ | Same electrical specs and RESET threshold (92.5%), but in 3mm × 3mm TDFN-EP package with 41°C/W θJA. | Better thermal performance in space-constrained modules; requires smaller PCB footprint and different land pattern. | Select for higher power density designs where board area is limited and thermal margin is critical. |
| TLV73350PDBVR | Lower Iq (450nA), lower current (300mA), narrower input (1.4V–5.5V), no RESET or automotive qualification. | Not suitable for automotive load-dump or cold-crank; limited to infotainment USB peripherals or non-safety sub-systems. | Consider only for non-automotive, low-voltage, ultra-low-power applications where RESET and AEC-Q100 are not required. |
Compared with MAX16910CASA9/V+T, the MAX16910CATA9/V+ offers superior thermal efficiency in compact layouts, while the TLV73350PDBVR trades automotive robustness for nanoamp quiescent current-making MAX16910CASA9/V+T the sole choice for AEC-Q100-compliant 5V bias rails requiring integrated RESET and load-dump immunity.

FAQ
What is the RESET threshold voltage for MAX16910CASA9/V+T?
The MAX16910CASA9/V+T features a fixed RESET threshold at 92.5% of the output voltage. For its +5V fixed output configuration, this equates to 4.625V nominal, with guaranteed operation between 4.5V and 4.7V over temperature and line/load conditions per datasheet Table 1. This threshold ensures early, deterministic reset assertion before microcontroller brownout.
Does MAX16910CASA9/V+T support adjustable output voltage?
Yes, MAX16910CASA9/V+T supports adjustable output voltage from +1.5V to +11V by connecting the SET pin to IN (or >2.4V) and using an external resistive divider between OUT and SETOV. The internal SETOV reference is 1.25V ±2.5%, enabling precise programmable regulation-though the MAX16910CASA9/V+T variant is typically used in +5V fixed mode per its ordering code suffix "9".
What package type and thermal characteristics does MAX16910CASA9/V+T have?
MAX16910CASA9/V+T uses an 8-pin SO-EP (5mm × 4mm) package with exposed pad. Its junction-to-ambient thermal resistance (θJA) is 53°C/W on a multilayer board, supporting 1861mW maximum power dissipation at +70°C ambient. The exposed pad must be soldered to PCB ground to achieve rated thermal performance and electrical stability.
How does the TIMEOUT pin function on MAX16910CASA9/V+T?
The TIMEOUT pin on MAX16910CASA9/V+T sets the duration that RESET remains low after VOUT recovers above threshold. With TIMEOUT open, the default delay is 60µs. Connecting a capacitor (e.g., 1nF) from TIMEOUT to GND extends the delay to 1.25ms, allowing customization for microprocessor reset timing requirements without external components.
Is MAX16910CASA9/V+T qualified for automotive use?
Yes, MAX16910CASA9/V+T is AEC-Q100 Grade 1 qualified (-40°C to +125°C ambient), with built-in thermal shutdown (+180°C trip), short-circuit protection (330mA typ), +45V input transient tolerance, and production-tested reliability for automotive ECU, BCM, and ADAS applications per ISO 16750 and ISO 7637 standards.
