Product details
Overview
MAX16910DASA8+T from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA at fixed +3.3V or +5V output (configurable via SETOV pin), 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 MAX16910DASA8+T datasheet, MAX16910DASA8+T pinout, MAX16910DASA8+T application, or MAX16910DASA8+T equivalent, key selection criteria include its 280mV dropout at 200mA, open-drain active-low RESET with 87.5% threshold and adjustable timeout, thermal/short-circuit protection, and -40°C to +125°C operation in the 5mm × 4mm SO-EP package.
Technical Context
The MAX16910DASA8+T implements a high-voltage BiCMOS DMOS linear regulation architecture with integrated feedback multiplexer (SETOV/SET-controlled), enabling seamless transition between fixed +3.3V/+5V and adjustable 1.5V–11V output modes. Its ENABLE input withstands +45V and features internal 0.65µA pulldown for reliable shutdown behavior.
RESET functionality combines voltage monitoring (87.5% VOUT threshold) with programmable timeout via external capacitor on TIMEOUT pin, while thermal protection triggers at +180°C with +25°C hysteresis and short-circuit current limiting at 330mA (typ).
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 without external clamping. |
| Output Current | Up to 200mA continuous - sufficient for microcontroller cores, CAN transceivers, and sensor interfaces in compact ECUs. |
| Quiescent Current | 20µA at no load - enables <100µA system standby power budgets required by modern automotive OEM specifications. |
| Dropout Voltage | 280mV at 200mA - ensures stable regulation down to VIN = VOUT + 0.28V, critical during low-battery cranking. |
| RESET Threshold | 87.5% of VOUT (fixed) - provides accurate brown-out detection with 5% hysteresis to prevent chatter during recovery. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood and body-control module placement per AEC-Q100 requirements. |
| Package | 8-pin SO-EP (5mm × 4mm) with exposed pad - delivers θJA = 53°C/W for thermally constrained PCB layouts. |
Pinout & Package
MAX16910DASA8+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 (θJC = 7°C/W).
| 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 fail-safe shutdown when floating. |
| 3 SET | Feedback mode selector | Grounded for fixed-output mode (+3.3V/+5V); driven >2.4V for adjustable mode using external resistive divider. |
| 4 RESET | Open-drain active-low reset | Asserts low during undervoltage, thermal shutdown, or ENABLE deactivation; sinks 0.5mA at ≤0.4V. |
| 5 TIMEOUT | Reset timeout adjust | Connects to GND via capacitor to extend default 60µs delay; supports microprocessor reset timing customization. |
| 6 SETOV | Output voltage selector | GND = +3.3V fixed; OUT = +5V fixed; external divider = adjustable 1.5V–11V output (VSETOV = 1.25V). |
| 7 GND | Power ground | Reference for all signals; must be connected to PCB ground plane; exposed pad tied to same node. |
| 8 OUT | Regulated output | Stabilized with ≥4.7µF low-ESR ceramic capacitor; supplies downstream logic, sensors, or communication ICs. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20µA at no load - meets stringent automotive module sleep-mode power targets without compromising startup speed. |
| Integrated RESET generator | Fixed 87.5% VOUT threshold with 60µs–multi-ms timeout - eliminates need for discrete reset IC and reduces BOM count. |
| Configurable output voltage | +3.3V or +5V fixed (via SETOV pin), or 1.5V–11V adjustable (external divider) - supports diverse SoC and peripheral voltage rails. |
| Robust fault protection | Thermal shutdown (+180°C), short-circuit limit (330mA typ), and +45V input tolerance - ensures reliability in harsh automotive environments. |
| Optimized for small footprint | Stable with 4.7µF output capacitor and 1µF input capacitor - minimizes board area and cost versus legacy regulators requiring larger ceramics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16910CASA8/V+ | Same SO-EP package and electrical specs, but automotive-qualified (AEC-Q100) and specified for 87.5% RESET threshold - identical pinout and footprint. | Targeted specifically for production automotive systems requiring full qualification documentation and traceability. | Select MAX16910CASA8/V+ when AEC-Q100 compliance and automotive-grade documentation are mandatory for Tier 1 supply chain. |
| TLE42754G | 5V fixed-output LDO with 30mA output, 45µA quiescent current, and integrated watchdog - lacks adjustable output and RESET timeout adjustment. | Suitable for simpler, lower-current automotive subsystems where RESET timing flexibility is not required. | Choose TLE42754G only for cost-sensitive, low-power applications where 200mA output and programmable RESET are unnecessary. |
Compared with MAX16910DASA8+T, MAX16910CASA8/V+ offers identical performance with formal automotive qualification, while TLE42754G trades output current and configurability for integrated watchdog and lower cost in non-demanding roles.

FAQ
What output voltage options does the MAX16910DASA8+T support?
The MAX16910DASA8+T supports +3.3V fixed output (SETOV = GND), +5V fixed output (SETOV = OUT), or adjustable 1.5V–11V output (SETOV connected to external resistive divider). The SET pin determines mode: grounded for fixed output, driven >2.4V for adjustable. All configurations are validated across -40°C to +125°C.
How does the RESET function operate on the MAX16910DASA8+T?
The MAX16910DASA8+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 default 60µs timeout - extendable with a capacitor on the TIMEOUT pin.
What is the thermal performance of the MAX16910DASA8+T in its SO-EP package?
The MAX16910DASA8+T in the 8-pin SO-EP package has θJA = 53°C/W and θJC = 7°C/W. With the exposed pad soldered to a multilayer PCB ground plane, it sustains 200mA output at +125°C ambient when VIN = 9V and VOUT = 5V - verified by derating curves in the datasheet Figure 1.
Can the MAX16910DASA8+T withstand automotive load-dump transients?
Yes - the MAX16910DASA8+T input (IN pin) is rated for +45V transients lasting ≤400ms, making it fully compatible with ISO 7637-2 Pulse 5a/b load-dump waveforms. No external TVS diode is required for standard 12V automotive systems, simplifying front-end protection design.
What is the minimum output capacitance required for stability with the MAX16910DASA8+T?
The MAX16910DASA8+T is stable with a minimum 4.7µF low-ESR ceramic capacitor (X7R/X5R) on the OUT pin for fixed +3.3V or +5V operation. For adjustable outputs, 10µF is recommended. Smaller capacitors risk instability; larger values (e.g., 22µF) improve transient response and PSRR without compromising stability.
