Product details
Overview
MAX16910DATA9+T from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA at +5V or +3.3V fixed output (this variant: 92.5% RESET threshold), operating from +3.5V to +30V input with +45V transient tolerance, and consuming only 20µA quiescent current - ideal for always-on automotive body control modules requiring cold-crank operation and load-dump resilience.
For engineers reviewing the MAX16910DATA9+T datasheet, MAX16910DATA9+T pinout, MAX16910DATA9+T application, or MAX16910DATA9+T equivalent, key selection criteria include its 280mV dropout at 200mA, open-drain active-low RESET with adjustable timeout, thermal/short-circuit protection, and TDFN-EP (3mm × 3mm, 8-pin) package optimized for high-temperature under-hood environments.
Technical Context
The MAX16910DATA9+T implements a BiCMOS DMOS linear regulation architecture with integrated thermal shutdown (+180°C trip, +25°C hysteresis) and 330mA short-circuit current limiting. Its SET/SETOV dual-input configuration enables mode selection between fixed +3.3V/+5V outputs or adjustable 1.5V–11V via external resistive divider, with internal 1.25V reference precision.
RESET functionality uses a dedicated comparator monitoring VOUT against factory-trimmed thresholds (92.5% for this variant), generating an open-drain low pulse with 60µs default timeout extendable via TIMEOUT pin capacitor. ENABLE withstands +45V and features internal 0.65µA pulldown for reliable shutdown control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +3.5V to +30V continuous; +45V tolerant for ≤400ms - supports automotive load-dump and cold-crank conditions |
| Quiescent Current | 20µA at no load - enables >10-year battery standby in always-on telematics modules |
| Output Current | Up to 200mA continuous - sufficient for MCU, CAN transceiver, and sensor power domains |
| Dropout Voltage | 280mV at 200mA - ensures regulation down to VIN = 5.28V for +5V output during cranking |
| RESET Threshold | 92.5% of VOUT (fixed) - provides precise brown-out detection for microcontroller reset coordination |
| Operating Temperature | -40°C to +125°C - qualified for AEC-Q100 Grade 1 automotive under-hood placement |
| Package | 8-pin TDFN-EP (3mm × 3mm) with exposed pad - achieves θJA = 41°C/W for efficient thermal management |
Pinout & Package
MAX16910DATA9+T is housed in an 8-pin thermally enhanced TDFN-EP package (3mm × 3mm) with exposed pad connected internally to GND. The exposed pad must be soldered to PCB ground plane using multiple vias for optimal thermal performance (θJC = 8°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator input | Bypassed with ≥1µF ceramic capacitor; accepts +3.5V–+30V supply and +45V transients |
| 2 ENABLE | Active-high enable | Internally pulled down (0.65µA); +45V tolerant - allows direct connection to battery or MCU GPIO |
| 3 SET | Feedback network selector | GND = fixed-output mode; ≥2.4V = adjustable mode using external resistor divider |
| 4 RESET | Open-drain active-low reset | Asserts low on VOUT undervoltage, ENABLE low, or thermal shutdown; requires external pull-up |
| 5 TIMEOUT | Reset timeout adjust | 60µs default delay; connect capacitor to GND for programmable timeout (e.g., 10ms with 8nF) |
| 6 SETOV | Output voltage selector | GND = +3.3V mode; OUT = +5V mode; external divider node for adjustable output (1.5V–11V) |
| 7 GND | Power ground | Reference for all signals; connects to exposed pad for thermal conduction |
| 8 OUT | Regulated output | Stable with ≥4.7µF ceramic capacitor; supplies downstream logic, sensors, or communication ICs |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20µA at no load - meets ISO 16750-2 Class D requirements for vehicle off-state leakage |
| Integrated RESET generator | Fixed 92.5% threshold with 60µs–multi-ms timeout - eliminates need for discrete reset IC in ECU designs |
| Robust automotive interface | +45V-tolerant ENABLE and IN pins - withstands load-dump events without external TVS |
| Thermal and fault protection | +180°C thermal shutdown with +25°C hysteresis and 330mA short-circuit limit - prevents damage during sustained overload |
| Flexible output configuration | Single device supports +3.3V, +5V, or 1.5V–11V outputs via pin-strapping or resistor divider - reduces BOM count across platforms |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16910DATA8/V+ | Identical package and specs except RESET threshold is 87.5% (vs. 92.5% for MAX16910DATA9+T) | Suitable where earlier reset assertion is required for slower-starting MCUs or legacy brown-out tolerances | Select when system requires reset assertion at deeper undervoltage (e.g., 4.34V for 5V rail) rather than 4.63V |
| TLE4275G | 5V fixed output, 150mA, 45µA IQ, SO-8 package, no adjustable RESET timeout or SETOV flexibility | Limited to fixed 5V output; lacks programmable reset delay and adjustable output capability | Choose for cost-sensitive, single-rail 5V applications where RESET timing is not critical and thermal performance is secondary |
Compared with MAX16910DATA8/V+, MAX16910DATA9+T offers higher reset threshold for tighter brown-out control; compared with TLE4275G, it delivers lower quiescent current, higher output current, adjustable reset timing, and flexible output configuration - making it superior for next-generation automotive ECUs demanding power efficiency and design reuse.

FAQ
What is the RESET threshold voltage for MAX16910DATA9+T?
The MAX16910DATA9+T features a fixed RESET threshold of 92.5% of the output voltage - for example, 4.625V on a +5V rail and 3.0525V on a +3.3V rail. This threshold is factory-trimmed and guaranteed over the full -40°C to +125°C temperature range, ensuring consistent brown-out detection across automotive operating conditions. The RESET output remains asserted low for a minimum of 60µs after VOUT exceeds this threshold.
Can MAX16910DATA9+T be used in adjustable output mode?
Yes, MAX16910DATA9+T supports adjustable output mode by connecting the SET pin to IN (or ≥2.4V) and configuring SETOV as the feedback node with an external resistive divider between OUT and GND. This enables output voltages from +1.5V to +11V using the formula VOUT = 1.25V × (1 + R1/R2). The device maintains 20µA quiescent current and full protection features in adjustable mode.
What package type does MAX16910DATA9+T use, and how should the exposed pad be handled?
MAX16910DATA9+T uses an 8-pin TDFN-EP package (3mm × 3mm) with an exposed thermal pad internally connected to GND. The pad must be soldered to a PCB ground plane using at least four thermal vias to achieve the specified θJA = 41°C/W. Failure to connect the pad degrades thermal performance and may trigger premature thermal shutdown under load.
How does the TIMEOUT pin affect MAX16910DATA9+T reset behavior?
The TIMEOUT pin on MAX16910DATA9+T sets the duration that RESET remains low after VOUT recovers above threshold. With TIMEOUT unconnected, the default delay is 60µs. Connecting a capacitor (e.g., 8nF) from TIMEOUT to GND extends the timeout - for instance, to 10ms - using the formula CTIMEOUT (nF) = 0.8 × ITO (μA) × TTIMEOUT (ms). Ceramic capacitors <10nA leakage are required.
Is MAX16910DATA9+T qualified for automotive applications?
Yes, MAX16910DATA9+T is AEC-Q100 qualified for Grade 1 (-40°C to +125°C ambient) operation and features automotive-specific design elements: +45V input transient tolerance, load-dump resilience, integrated thermal shutdown (+180°C trip), short-circuit protection (330mA), and robust ESD performance (2.5kV HBM). It is manufactured and tested to meet automotive reliability and traceability standards.
