Product details
Overview
MAX16910CASA8+ from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA output with only 20µA no-load supply current and 1.6µA shutdown current. It operates from +3.5V to +30V input, withstands +45V transients, and supports fixed +3.3V or +5V outputs (this variant uses 87.5% RESET threshold). It is deployed in battery-powered automotive ECUs requiring cold-crank operation and load-dump resilience.
For engineers reviewing the MAX16910CASA8+ datasheet, MAX16910CASA8+ pinout, MAX16910CASA8+ application, or MAX16910CASA8+ equivalent, key selection criteria include its 280mV dropout at 200mA, open-drain active-low RESET with adjustable timeout, thermal/short-circuit protection, and SO-EP package compatibility with industrial temperature range (-40°C to +125°C).
Technical Context
The MAX16910CASA8+ integrates a high-voltage pass transistor with precision bandgap reference and internal feedback multiplexer for mode selection (fixed 3.3V/5V or adjustable via external divider). Its control logic monitors output voltage against two factory-set RESET thresholds (87.5% or 92.5% of VOUT) and triggers a fixed 60µs or capacitor-extended timeout period.
Thermal protection activates at +180°C junction temperature with +25°C hysteresis, while short-circuit current limiting caps output at 330mA (typ). The ENABLE input is active-high with 45V tolerance and internal 0.65µA pulldown, enabling direct connection to VIN 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 - enables operation during automotive load-dump events. |
| Quiescent Current | 20µA at no load - meets <100µA module standby requirements for ISO 26262-compliant systems. |
| Output Current | Up to 200mA continuous - sufficient for powering microcontrollers, CAN transceivers, and sensor interfaces. |
| Dropout Voltage | 280mV at 200mA - ensures regulation down to VIN = VOUT + 0.28V, critical for cold-crank (6V) start-up. |
| RESET Threshold | 87.5% of VOUT (fixed) - provides early fault detection before system reset becomes unsafe. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive environments per AEC-Q100. |
| Package | 8-pin SO-EP (5mm × 4mm) - thermally enhanced with exposed pad tied to GND for improved θJA (53°C/W). |
Pinout & Package
MAX16910CASA8+ is housed in an 8-pin SO-EP (small-outline, exposed pad) package measuring 5mm × 4mm. The exposed pad (EP) is internally connected to GND and must be soldered to the PCB ground plane to achieve specified thermal performance (θJC = 7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator input | Bypass with ≥1µF low-ESR ceramic capacitor; accepts +3.5V–+30V and tolerates +45V transients. |
| 2 ENABLE | Active-high enable | Drives device ON when >2.4V; internal 0.65µA pulldown ensures safe shutdown if left floating or driven high-impedance. |
| 3 SET | Feedback mode selector | Grounded for fixed-output mode (+3.3V or +5V); pulled high (>2.4V) for adjustable mode using external resistor divider. |
| 4 RESET | Open-drain active-low reset | Asserts low when VOUT falls below 87.5% threshold or during ENABLE=LOW/thermal shutdown; requires external pull-up. |
| 5 TIMEOUT | Reset timeout adjust | Leaving unconnected yields 60µs default delay; adding capacitor extends timeout linearly (1.25ms/nF). |
| 6 SETOV | Output voltage selector | Connected to GND for +3.3V fixed output; to OUT for +5V fixed output; to resistive divider for adjustable 1.5V–11V outputs. |
| 7 GND | Power ground | Reference node for all circuitry; EP pad must be connected to same ground plane for thermal integrity. |
| 8 OUT | Regulated output | Stable with ≥4.7µF low-ESR ceramic capacitor; delivers up to 200mA with 280mV dropout at full load. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20µA no-load operation enables >1-year battery life in always-on automotive modules. |
| Integrated RESET generator | Eliminates need for discrete reset IC by providing accurate, adjustable-delay active-low signal synchronized to VOUT. |
| Load-dump robustness | +45V input tolerance and thermal/short-circuit protection ensure survival during ISO 7637-2 Pulse 5a events. |
| Flexible output configuration | Single device supports +3.3V, +5V fixed outputs or 1.5V–11V adjustable via external resistors - reduces BOM count. |
| Thermally enhanced SO-EP package | Exposed pad lowers junction-to-ambient thermal resistance to 53°C/W, enabling higher power dissipation at elevated ambient temperatures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16910CATA8+ | Same electrical specs but in 3mm × 3mm TDFN-EP package with lower θJA (41°C/W) and smaller footprint. | Better suited for space-constrained PCBs where thermal performance outweighs SO package handling advantages. | Select MAX16910CATA8+ when board area is limited and thermal design allows fine-pitch reflow. |
| TPS7B8733QKVURQ1 | Lower quiescent current (15µA), 3.3V fixed output only, no adjustable mode or RESET output. | Lacks integrated RESET and voltage selection flexibility; requires external reset IC for system monitoring. | Choose TPS7B8733QKVURQ1 only when 3.3V-only supply and minimal IQ are primary constraints and RESET functionality is handled elsewhere. |
Compared with MAX16910CASA8+, MAX16910CATA8+ offers superior thermal efficiency in compact layouts, while TPS7B8733QKVURQ1 trades configurability and integrated supervision for marginally lower IQ - making MAX16910CASA8+ optimal for mixed-voltage, RESET-dependent automotive subsystems.

FAQ
What is the RESET threshold voltage for MAX16910CASA8+?
The MAX16910CASA8+ features a fixed RESET threshold at 87.5% of the regulated output voltage. For example, with a +5V output, RESET asserts low when VOUT drops below 4.375V and remains low for ≥60µs after recovery. This threshold is factory-set and not user-adjustable on this variant.
Can MAX16910CASA8+ be used in adjustable-output configurations?
Yes, MAX16910CASA8+ supports adjustable output voltages 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 output follows VOUT = 1.25V × (1 + R1/R2), where R2 ≤ 100kΩ ensures accuracy.
What package type does MAX16910CASA8+ use, and how should the exposed pad be handled?
MAX16910CASA8+ uses an 8-pin SO-EP (small-outline with exposed pad) package measuring 5mm × 4mm. The exposed pad (EP) is internally connected to GND and must be soldered to the PCB ground plane using multiple thermal vias to achieve the specified θJA of 53°C/W and prevent thermal shutdown under load.
How does MAX16910CASA8+ behave during automotive load-dump events?
MAX16910CASA8+ withstands +45V transients on the IN pin for ≤400ms per ISO 7637-2 Pulse 5a, maintaining regulation and protecting downstream circuitry. Its internal thermal and short-circuit protections remain active during such events, preventing latch-up or permanent damage without external components.
Is MAX16910CASA8+ pin-compatible with other variants in the MAX16910 family?
Yes, MAX16910CASA8+ shares identical pinout and footprint with all other SO-EP variants (e.g., MAX16910CASA9+, MAX16910DASA8+/V+), differing only in RESET threshold (87.5% vs. 92.5%) or qualification grade (automotive vs. industrial). No PCB redesign is needed when substituting within the SO-EP package group.
