Product details
Overview
The MAX16910CASA9/V+ 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 uses 92.5% RESET threshold), operating from +3.5V to +30V input with +45V transient tolerance-designed for battery-powered and cold-crank automotive systems.
For engineers reviewing the MAX16910CASA9/V+ datasheet, MAX16910CASA9/V+ pinout, MAX16910CASA9/V+ application, or MAX16910CASA9/V+ equivalent, this page provides verified technical context, validated pin functions, confirmed thermal and electrical specs, and real-world automotive use cases with design-meaningful parameter mapping.
Technical Context
This device implements a high-voltage BiCMOS DMOS linear regulation architecture with integrated thermal shutdown (+180°C trip, +25°C hysteresis) and short-circuit protection (330mA limit). Its RESET circuit uses internal voltage comparators referenced to 92.5% of VOUT, with fixed 60µs timeout extendable via external capacitor on TIMEOUT pin.
The ENABLE input is active-high with internal 0.65µA pulldown, tolerating up to +45V, enabling direct connection to battery rail. SET and SETOV pins configure operation mode: fixed +3.3V/+5V or adjustable 1.5V–11V output using external resistive divider with 1.25V feedback reference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +3.5V to +30V continuous; +45V tolerant for ≤400ms-supports load-dump survival in 12V/24V automotive systems. |
| Quiescent Current | 20µA at no load-enables >10-year battery standby in always-on modules like telematics or alarm controllers. |
| Shutdown Current | 1.6µA at +25°C-reduces parasitic drain during vehicle sleep mode. |
| Output Current | 200mA max continuous-sufficient for MCU cores, CAN transceivers, and sensor interfaces without external pass devices. |
| Dropout Voltage | 280mV at 200mA (5V output)-maintains regulation down to VIN = 5.28V, critical for cold-crank (6V) operation. |
| RESET Threshold | 92.5% of VOUT (falling edge)-ensures deterministic microcontroller reset before brownout, with 4µs propagation delay. |
| Operating Temperature | -40°C to +125°C ambient-qualified per AEC-Q100 for under-hood and infotainment applications. |
Pinout & Package
MAX16910CASA9/V+ is supplied in an 8-pin SO-EP package (5mm × 4mm), thermally enhanced with exposed pad connected to GND. Pin 1 is IN; Pin 8 is OUT; Pin 4 is open-drain RESET; Pin 5 is TIMEOUT adjust; Pin 6 is SETOV; Pin 7 is GND; Pin 2 is ENABLE; Pin 3 is SET.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Regulator input | Bypassed with ≥1µF low-ESR ceramic; withstands +45V transients-connects directly to battery rail. |
| ENABLE | Active-high enable | Internally pulled down (0.65µA); +45V tolerant-allows direct tie to IN for always-on operation. |
| SET | Feedback network selector | GND = fixed-output mode; ≥2.4V = adjustable mode-configures internal vs. external resistor divider. |
| RESET | Open-drain active-low reset | Asserts low when VOUT < 92.5% nominal or during thermal shutdown-drives µC reset pin directly. |
| TIMEOUT | Reset timeout adjust | Unconnected = 60µs default; capacitor to GND extends delay-eliminates need for external RC timing. |
| SETOV | Output voltage selector / FB node | GND = 3.3V mode; OUT = 5V mode; external divider = 1.5–11V-sets regulated output via internal 1.25V reference. |
| GND | Power ground | Reference for all signals; exposed pad must be soldered to PCB ground plane for thermal performance. |
| OUT | Regulated output | Stable with ≥4.7µF ceramic capacitor-powers downstream logic with low noise and fast transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20µA enables >10-year battery life in always-on automotive modules such as keyless entry receivers. |
| Integrated RESET with programmable timeout | Eliminates discrete reset IC; 60µs base delay extendable via TIMEOUT capacitor-simplifies BOM and layout. |
| Fixed +3.3V/+5V or adjustable 1.5V–11V output | Single part supports multiple system rails; SET/SETOV configuration avoids redesign for voltage changes. |
| +45V input transient tolerance | Survives ISO 7637-2 Pulse 5a load-dump events without external TVS-reduces protection component count. |
| Thermal and short-circuit protection | +180°C shutdown with +25°C hysteresis and 330mA current limit-prevents damage during sustained overload. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16910CASA8/V+ | Same SO-EP package and specs, but 87.5% RESET threshold (vs. 92.5% for MAX16910CASA9/V+) | Suitable where earlier reset assertion is required-e.g., systems with tighter VOUT margin or higher PSRR sensitivity | Select MAX16910CASA8/V+ only if design requires lower reset threshold; otherwise MAX16910CASA9/V+ offers more conservative brownout detection. |
| TLE42754G | 5V fixed output, 150mA, 40µA IQ, +40V transient rating, no adjustable output or RESET timeout adjustment | Limited to fixed 5V use; lacks programmable RESET delay and adjustable output-requires redesign for 3.3V or custom voltages | Choose TLE42754G only for cost-sensitive, fixed-rail applications where 200mA and ultra-low IQ are not required. |
Compared with MAX16910CASA8/V+, MAX16910CASA9/V+ provides earlier reset deassertion (92.5% vs. 87.5%), improving system robustness against marginal VOUT dips; versus TLE42754G, it delivers 33% higher current, half the quiescent current, and configurable functionality-justifying its use in next-gen ADAS and telematics platforms.

FAQ
What is the RESET threshold voltage for MAX16910CASA9/V+?
The MAX16910CASA9/V+ features a fixed RESET threshold of 92.5% of the output voltage (e.g., 4.625V for a 5V output), with 5% hysteresis on rising edge. This value is factory-set and cannot be adjusted-confirmed in the Ordering Information table and Electrical Characteristics section of the datasheet.
Can MAX16910CASA9/V+ be used in adjustable-output mode?
Yes, MAX16910CASA9/V+ supports adjustable output from +1.5V to +11V by connecting SET to IN (or ≥2.4V) and using an external resistive divider between OUT and SETOV. The internal 1.25V reference and SETOV pin enable precise voltage setting per the equation VOUT = 1.25V × (1 + R1/R2).
What package type does MAX16910CASA9/V+ use?
MAX16910CASA9/V+ 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 specified thermal resistance (θJA = 53°C/W).
Does MAX16910CASA9/V+ include thermal protection?
Yes, MAX16910CASA9/V+ incorporates thermal shutdown that activates at +180°C junction temperature, with +25°C hysteresis. When triggered, the pass transistor turns off until die temperature falls to +155°C, then automatically resumes regulation-protecting against sustained overload conditions.
What is the maximum output current capability of MAX16910CASA9/V+?
MAX16910CASA9/V+ delivers up to 200mA continuous output current. Actual available current depends on ambient temperature, input-output voltage differential, and PCB thermal design-e.g., at TA = +125°C, VIN = 16V, VOUT = 3.3V, max safe current is ~48mA (calculated from 609mW allowable dissipation).
