Product details
Overview
MAX16910CASA8/V+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 (87.5% RESET threshold), operating from +3.5V to +30V input with +45V transient tolerance and 20µA no-load supply current. It integrates open-drain RESET, ENABLE control, thermal/short-circuit protection, and supports cold-crank operation in vehicle body control modules.
For engineers reviewing the MAX16910CASA8/V+T datasheet, MAX16910CASA8/V+T pinout, MAX16910CASA8/V+T application, or MAX16910CASA8/V+T equivalent, key selection criteria include its 20µA quiescent current, 280mV dropout at 200mA, -40°C to +125°C automotive temperature range, 8-pin SO-EP package, and configurable fixed/adjustable output voltage mode.
Technical Context
The MAX16910CASA8/V+T employs a BiCMOS DMOS pass transistor architecture optimized for high-voltage automotive line regulation under load-dump and cold-crank conditions. Its internal feedback network enables precise +3.3V or +5V outputs, while SETOV/SET pin logic selects between fixed and adjustable modes using external resistive dividers for 1.5V–11V outputs.
RESET functionality uses dual fixed thresholds (87.5% or 92.5% of VOUT) with 60µs default timeout extendable via TIMEOUT capacitor; ENABLE withstands +45V and features internal 0.65µA pulldown for reliable shutdown control without external pull-down resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +3.5V to +30V continuous, +45V transient tolerant - survives automotive load-dump events without external clamping. |
| Quiescent Current | 20µA at no load - enables always-on systems meeting <100µA module standby requirements. |
| Output Current | Up to 200mA - sufficient for MCU core rails, CAN transceivers, and sensor interfaces in compact ECUs. |
| Dropout Voltage | 280mV at 200mA - maintains regulation during cold-crank down to ~4.5V battery voltage with +5V output. |
| RESET Threshold | 87.5% of VOUT (fixed) - asserts low when output drops below 4.375V (for 5V mode), ensuring deterministic microcontroller reset timing. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive applications per AEC-Q100 stress test requirements. |
| Package | 8-pin SO-EP (5mm × 4mm) with exposed pad - provides 53°C/W θJA for thermal management in space-constrained PCB layouts. |
Pinout & Package
MAX16910CASA8/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 (θJC = 7°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 input | Internally pulled down (0.65µA); drives high to activate regulator; tolerates +45V for direct battery connection. |
| 3 SET | Feedback network selector | Grounded for fixed-output mode (+3.3V/+5V); tied to IN (>2.4V) for adjustable mode with external resistor divider. |
| 4 RESET | Open-drain active-low reset output | Sinks 0.5mA at 0.4V; asserts low on undervoltage, ENABLE deactivation, or thermal shutdown. |
| 5 TIMEOUT | Reset timeout period adjust | Leaving unconnected yields 60µs delay; adding capacitor extends timeout linearly (1.25ms/nF scaling). |
| 6 SETOV | Output voltage selector / feedback node | Connected to GND for +3.3V mode, to OUT for +5V mode, or to resistor divider for adjustable output (1.5V–11V). |
| 7 GND | Power ground reference | Primary return path; exposed pad must be connected to same ground plane for thermal integrity. |
| 8 OUT | Regulated output | Stabilized with ≥4.7µF ceramic capacitor; delivers up to 200mA with ±1% output accuracy over temperature. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20µA at no load - reduces parasitic drain in always-on automotive modules, extending battery life during extended parking. |
| Integrated RESET with programmable delay | Fixed 87.5% threshold + 60µs base timeout - eliminates need for discrete reset IC and external RC timing components. |
| Robust input transient tolerance | +45V absolute max on IN and ENABLE - sustains operation during ISO 7637-2 Pulse 5a load-dump without external TVS diodes. |
| Thermal and short-circuit protection | +180°C shutdown with +25°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
| Configurable output voltage | +3.3V or +5V fixed, or 1.5V–11V adjustable via external resistors - supports diverse SoC, MCU, and peripheral 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 |
|---|---|---|---|
| MAX16910CATA8/V+ | TDFN-EP (3mm × 3mm) package vs. SO-EP; identical electrical specs and 87.5% RESET threshold. | Better thermal performance (θJA = 41°C/W) but requires tighter layout clearance and reflow-compatible footprint. | Select MAX16910CATA8/V+ when board space is constrained and thermal headroom is critical; MAX16910CASA8/V+ preferred for ease of assembly and legacy SO footprint compatibility. |
| TPS7B8750QKVURQ1 | 500mA output, 27µA IQ, 300mV dropout at 500mA; fixed 5V only; no RESET output. | Lacks integrated RESET and adjustable output, requiring external supervisor IC for system reset functionality. | Choose TPS7B8750QKVURQ1 only if higher current and lower dropout are mandatory and RESET can be implemented separately. |
Compared with MAX16910CASA8/V+, the MAX16910CATA8/V+ offers superior thermal dissipation in smaller area, while the TPS7B8750QKVURQ1 trades integrated supervision for higher current capability-neither is pin-compatible, and both require PCB layout changes.

FAQ
What is the RESET threshold voltage for MAX16910CASA8/V+T?
The MAX16910CASA8/V+T features an 87.5% RESET threshold, meaning it asserts the open-drain RESET output low when the regulated output voltage falls below 87.5% of its nominal value - e.g., 4.375V for a +5V output or 2.8875V for a +3.3V output. This threshold is factory-configured and not user-adjustable on this variant.
Can MAX16910CASA8/V+T be used in adjustable output mode?
Yes, MAX16910CASA8/V+T supports adjustable output mode: connect SET to IN (or >2.4V), then use a resistive divider between OUT and SETOV to set output voltages from +1.5V to +11V. The internal SETOV reference is 1.25V, and the formula is VOUT = 1.25V × (1 + R1/R2), where R2 ≤ 100kΩ.
What package type does MAX16910CASA8/V+T use?
MAX16910CASA8/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 specified thermal performance (θJA = 53°C/W).
How does the TIMEOUT pin affect RESET timing on MAX16910CASA8/V+T?
On MAX16910CASA8/V+T, leaving the TIMEOUT pin unconnected yields a fixed 60µs RESET timeout period after VOUT exceeds its threshold. Connecting a capacitor from TIMEOUT to GND extends the delay linearly: CTIMEOUT (nF) = 1.25 × TTIMEOUT (ms). For example, a 10nF capacitor sets ~8ms timeout.
Is MAX16910CASA8/V+T qualified for automotive applications?
Yes, MAX16910CASA8/V+T is AEC-Q100 qualified for automotive use, operating across -40°C to +125°C ambient temperature with built-in thermal shutdown (+180°C trip), short-circuit protection (330mA limit), and +45V input transient tolerance - meeting ISO 7637-2 load-dump requirements without external protection.
