Product details
Overview
MAX16910DASA9/V+T from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA at +5V fixed output with 20µA no-load supply current, 280mV dropout at 200mA, and +45V input transient tolerance-designed for battery-backed ECUs and infotainment power rails.
For engineers reviewing the MAX16910DASA9/V+T datasheet, MAX16910DASA9/V+T pinout, MAX16910DASA9/V+T application, or MAX16910DASA9/V+T equivalent, this page provides verified package mapping (8-pin SO-EP), RESET threshold (92.5% of VOUT), thermal shutdown (+180°C), enable logic-high interface, and automotive-grade (-40°C to +125°C) operation confirmed per Analog Devices' Rev 9 datasheet.
Technical Context
The MAX16910DASA9/V+T implements a BiCMOS DMOS linear regulation architecture with internal feedback multiplexing for fixed (+3.3V/+5V) or adjustable (1.5V–11V) outputs via SET/SETOV control. Its open-drain RESET output features factory-trimmed 92.5% falling-edge threshold and 60µs default timeout, extendable with external capacitor on TIMEOUT pin.
Thermal protection activates at +180°C junction temperature with +25°C hysteresis; short-circuit current limit is 330mA (typ). ENABLE withstands +45V and includes internal 0.65µA pulldown, enabling direct connection to IN for always-on operation without external pull-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +3.5V to +30V continuous, +45V transient tolerant-supports cold-crank and load-dump conditions in 12V/24V automotive systems. |
| Quiescent Current | 20µA at no load-enables >1-year battery standby in always-on modules without compromising low-power requirements. |
| Output Current | 200mA continuous-sufficient for powering microcontrollers, CAN transceivers, and sensor interfaces in body control units. |
| Dropout Voltage | 280mV at 200mA-ensures regulation down to VIN = 5.28V for +5V output, critical during engine cranking. |
| RESET Threshold | 92.5% of VOUT (falling edge)-provides precise brown-out detection aligned with MCU reset requirements. |
| Operating Temp | -40°C to +125°C ambient-qualified per AEC-Q100 for under-hood and dashboard-mounted automotive electronics. |
| Package | 8-pin SO-EP (5mm × 4mm) with exposed pad-enables 53°C/W θJA and robust thermal dissipation in compact PCB layouts. |
Pinout & Package
MAX16910DASA9/V+T 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 (θJA = 53°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator input | Bypassed with ≥1µF ceramic capacitor; accepts +3.5V–+30V input and withstands +45V transients. |
| 2 ENABLE | Active-high enable | Logic-high (>2.4V) enables regulation; internally pulled down (0.65µA) for safe default-off state. |
| 3 SET | Feedback mode selector | GND selects fixed-output mode; >2.4V selects adjustable mode using external resistive divider. |
| 4 RESET | Open-drain active-low reset | Asserts low when VOUT falls below 92.5% threshold; remains low for 60µs minimum after recovery. |
| 5 TIMEOUT | Reset timeout adjust | Open circuit yields 60µs delay; capacitor to GND extends timeout linearly (1.25ms/nF). |
| 6 SETOV | Output voltage selector | GND sets +3.3V output; OUT sets +5V output; external divider sets 1.5V–11V adjustable output. |
| 7 GND | Power ground | Reference for all signals; must be connected to PCB ground plane and tied to exposed pad. |
| 8 OUT | Regulated output | Stable +5V (fixed) output; requires ≥4.7µF low-ESR ceramic capacitor for stability across -40°C to +125°C. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20µA at no load-meets stringent ISO 16750-2 sleep-mode leakage limits for automotive modules. |
| Integrated RESET generator | Factory-trimmed 92.5% threshold with adjustable timeout-eliminates need for discrete reset IC and saves BOM cost. |
| Robust input tolerance | +45V transient rating on IN and ENABLE-survives load-dump events without external TVS diodes. |
| Thermal and short-circuit protection | +180°C shutdown with +25°C hysteresis and 330mA current limit-prevents damage during sustained overload. |
| Flexible output configuration | +3.3V/+5V fixed or 1.5V–11V adjustable via resistor divider-supports diverse SoC and MCU core/logic rail requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16910CASA9/V+ | TDFN-EP (3mm × 3mm) package instead of SO-EP; identical electrical specs and RESET threshold (92.5%). | Better thermal performance (θJA = 41°C/W) but requires smaller land pattern and tighter assembly control. | Select for space-constrained designs where thermal headroom is critical and TDFN reflow capability exists. |
| TLV73350PDBVR | Lower voltage range (1.7V–5.5V input), 300mA output, 35µA IQ, no RESET or automotive qualification. | Not suitable for 12V/24V automotive systems; limited to low-voltage portable or industrial applications. | Consider only for non-automotive, low-input-voltage designs where RESET and AEC-Q100 are not required. |
Compared with MAX16910CASA9/V+, the MAX16910DASA9/V+T offers larger SO-EP footprint for easier assembly and higher θJA, while TLV73350PDBVR lacks automotive qualification, high-voltage tolerance, and integrated RESET-making it unsuitable as a drop-in replacement.

FAQ
What is the RESET threshold voltage for MAX16910DASA9/V+T?
The MAX16910DASA9/V+T features a fixed RESET threshold of 92.5% of the output voltage (VOUT), specified as falling-edge detection. For its +5V fixed output configuration, this corresponds to 4.625V nominal, with ±2.5% variation over temperature and load. The RESET output remains asserted low for a minimum of 60µs after VOUT exceeds the threshold, and the timeout can be extended using an external capacitor on the TIMEOUT pin.
Does MAX16910DASA9/V+T support adjustable output voltage?
Yes, MAX16910DASA9/V+T supports adjustable output voltage from +1.5V to +11V by configuring SET to >2.4V (e.g., connect to IN) and using an external resistive divider between OUT and SETOV. The output is calculated as VOUT = 1.25V × (1 + R1/R2), where R2 ≤ 100kΩ. This mode is distinct from its +3.3V/+5V fixed-output configurations and requires no hardware changes beyond resistor selection.
What package type does MAX16910DASA9/V+T use?
MAX16910DASA9/V+T 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 the specified thermal resistance (θJA = 53°C/W). This package differs from the TDFN-EP variant (e.g., MAX16910CATA9/V+) and supports standard SOIC assembly processes.
How does the ENABLE pin function on MAX16910DASA9/V+T?
The ENABLE pin on MAX16910DASA9/V+T is an active-high logic input with VIH = 2.4V minimum and VIL = 0.4V maximum. It includes an internal 0.65µA pulldown current, ensuring safe shutdown when left floating or driven high-impedance. ENABLE tolerates up to +45V, allowing direct connection to the IN rail for always-on operation without external components.
Is MAX16910DASA9/V+T qualified for automotive applications?
Yes, MAX16910DASA9/V+T is explicitly automotive-qualified, indicated by the "/V+" suffix in its part number. It meets AEC-Q100 Grade 1 requirements with guaranteed operation from -40°C to +125°C ambient temperature, +45V input transient tolerance, and built-in thermal shutdown (+180°C) and short-circuit protection-fully documented in Analog Devices' official datasheet Rev 9.
