Product details
Overview
MAX16910CASA9+ from Analog Devices is an automotive-qualified, ultra-low quiescent current linear regulator delivering up to 200mA output with 20µA no-load supply current and 1.6µA shutdown current. It operates from +3.5V to +30V input, withstands +45V transients, and supports fixed +5V output (92.5% RESET threshold) in an 8-pin SO-EP package. It is used in automotive body control modules requiring cold-crank operation and load-dump immunity.
For engineers reviewing the MAX16910CASA9+ datasheet, MAX16910CASA9+ pinout, MAX16910CASA9+ application, or MAX16910CASA9+ equivalent, key selection criteria include its 280mV dropout at 200mA, open-drain active-low RESET with adjustable timeout, thermal/short-circuit protection, and -40°C to +125°C operating range - all critical for automotive power rail design.
Technical Context
The MAX16910CASA9+ implements a high-voltage BiCMOS DMOS linear regulation architecture with integrated feedback multiplexer, enabling user-selectable fixed (+3.3V/+5V) or adjustable (1.5V–11V) output via SET/SETOV configuration. Its internal 1.25V reference and precision voltage divider sensing support ±1% output accuracy over temperature and line/load conditions.
RESET functionality uses dual fixed thresholds (92.5% of VOUT for this variant), with a 60µs default timeout extendable via external capacitor on TIMEOUT pin. ENABLE is active-high with +45V tolerance and internal 0.65µA pulldown, allowing direct connection to battery without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +3.5V to +30V continuous; +45V transient tolerant - survives automotive load-dump events. |
| Output Current | Up to 200mA continuous - sufficient for microcontroller core rails and CAN transceivers. |
| Quiescent Current | 20µA at no load - enables >10-year battery standby in always-on automotive modules. |
| Shutdown Current | 1.6µA - meets ISO 16750-2 "sleep mode" leakage requirements. |
| Dropout Voltage | 280mV at 200mA - sustains regulation during cold-crank down to 3.5V battery. |
| RESET Threshold | 92.5% of VOUT (fixed) - ensures reliable µC reset before brownout at 5V output. |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive placement per AEC-Q100. |
Pinout & Package
MAX16910CASA9+ is housed in an 8-pin SO-EP (5mm × 4mm) package with exposed thermal pad connected internally to GND. The package provides 53°C/W junction-to-ambient thermal resistance and supports reflow soldering at +260°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator input | Battery input connection; requires ≥1µF low-ESR ceramic bypass to GND. |
| 2 ENABLE | Active-high enable | Drives regulator ON/OFF; +45V tolerant, internally pulled down to GND. |
| 3 SET | Feedback mode selector | GND = fixed output mode; >2.4V = adjustable output mode using external divider. |
| 4 RESET | Open-drain active-low reset | Asserts low during undervoltage, thermal shutdown, or ENABLE deactivation. |
| 5 TIMEOUT | Reset timeout adjust | Connect capacitor to GND to extend default 60µs delay; unconnected = 60µs. |
| 6 SETOV | Output voltage selector | GND = 3.3V fixed; OUT = 5V fixed; external divider = adjustable (1.5V–11V). |
| 7 GND | Power ground | Reference for all signals; connect exposed pad to PCB ground plane for thermal relief. |
| 8 OUT | Regulated output | Delivers stable 5V (this variant); requires ≥4.7µF low-ESR ceramic output capacitor. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16910CATA9+ | TDFN-EP (3mm × 3mm) package; 41°C/W θJA vs. 53°C/W for SO-EP; identical electrical specs. | Better thermal performance in space-constrained layouts; requires different land pattern and reflow profile. | Select for higher power density or tighter thermal budgets; verify PCB layout compatibility. |
| TLV73350PDBVR | Lower IQ (250nA), lower current (300mA), but only +5.5V max input; no RESET or automotive qualification. | Not suitable for 12V/24V automotive systems; lacks load-dump tolerance and AEC-Q100 rating. | Consider only for non-automotive, low-power battery devices where input < +5.5V and RESET not required. |
Compared with MAX16910CASA9+, the MAX16910CATA9+ offers superior thermal dissipation in smaller footprint, while TLV73350PDBVR trades automotive robustness for ultra-low IQ in low-voltage consumer applications - neither is pin-compatible, and both require board-level redesign.

FAQ
What is the RESET threshold voltage for MAX16910CASA9+?
The MAX16910CASA9+ features a fixed RESET threshold of 92.5% of the output voltage. With its +5V fixed output configuration, this corresponds to 4.625V nominal, guaranteed between 4.5V and 4.75V across -40°C to +125°C. The RESET output remains asserted low for 60µs after VOUT exceeds this threshold, and the delay can be extended using an external capacitor on the TIMEOUT pin.
Can MAX16910CASA9+ operate during automotive cold-crank conditions?
Yes, MAX16910CASA9+ is explicitly designed for cold-crank operation. With a minimum input voltage of +3.5V and a dropout voltage of only 280mV at 200mA, it maintains regulated +5V output even when battery voltage sags to 3.5V. Its -40°C to +125°C operating range and automotive qualification ensure reliable function during engine start-up in extreme ambient temperatures.
What package type does MAX16910CASA9+ use, and how is thermal management handled?
MAX16910CASA9+ uses an 8-pin SO-EP (5mm × 4mm) package with exposed thermal pad internally connected to GND. Thermal management relies on soldering the exposed pad to a PCB ground plane using multiple vias. This achieves a junction-to-ambient thermal resistance of 53°C/W, enabling safe operation up to 1861mW at +70°C ambient, with derating above that temperature.
Does MAX16910CASA9+ support adjustable output voltage?
No, MAX16910CASA9+ is factory-configured for fixed +5V output with 92.5% RESET threshold. Adjustable output (1.5V–11V) requires connecting SET to IN (or >2.4V) and using an external resistive divider between OUT and SETOV - but this configuration is not supported by the MAX16910CASA9+ variant's internal trimming and is not validated per its datasheet ordering guide.
How does the ENABLE pin function on MAX16910CASA9+?
The ENABLE pin on MAX16910CASA9+ is an active-high logic input with +45V absolute maximum rating. It features an internal 0.65µA pulldown current, ensuring automatic shutdown when left floating or driven high-impedance. Driving ENABLE high (≥2.4V) enables regulation; pulling it low (≤0.4V) places the device in 1.6µA shutdown mode - ideal for ignition-controlled power sequencing in automotive systems.
