Product details
Overview
MAX15006AASA/V+ from Maxim Integrated is an automotive-qualified, ultra-low quiescent-current linear regulator with fixed 3.3V output, 4V–40V input range, 50mA guaranteed output current, and 10μA no-load ground current. It features thermal shutdown, short-circuit protection, and operates across –40°C to +125°C in an 8-pin SO-EP package-designed for battery-sensitive automotive subsystems like tire-pressure monitoring sensors.
For engineers reviewing the MAX15006AASA/V+ datasheet, MAX15006AASA/V+ pinout, MAX15006AASA/V+ application, or MAX15006AASA/V+ equivalent, key selection criteria include cold-crank operation (down to 4V), 45V load-dump tolerance, low dropout (1000mV at 50mA), stable operation with 2.2μF ceramic output capacitor, and automotive AEC-Q100 qualification status.
Technical Context
The MAX15006AASA/V+ uses an internal p-channel pass device to maintain ultra-low quiescent current (10μA no load, 90μA full load) across its full –40°C to +125°C operating range. Its regulation architecture relies on a 1.23V internal reference and error amplifier, with output voltage accuracy of ±1.5% over temperature and line/load conditions.
Unlike the MAX15007 series, this variant lacks an enable (EN) input-confirmed by pin configuration tables showing EN pin absent in MAX15006A variants. It supports continuous short-circuit operation with automatic thermal cycling at +165°C junction shutdown and 20°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - enables direct connection to automotive battery rails including cold-crank (4.5V) and load-dump (45V absolute max) transients. |
| Output Voltage | Fixed 3.3V (±1.5%) - tightly regulated for powering microcontrollers, CAN transceivers, and RF modules in automotive ECUs. |
| Max Output Current | 50mA - sufficient for low-power sensor signal conditioning, EEPROM, and logic-level interface ICs without external boost. |
| Quiescent Current | 10μA at no load - preserves battery life in always-on vehicle systems such as TPMS and telematics wake-up circuits. |
| Dropout Voltage | 1000mV at 50mA - ensures regulation down to VIN = 4.3V, critical for engine-off battery operation in 12V systems. |
| Thermal Shutdown | +165°C with 20°C hysteresis - protects against sustained overload or poor PCB heatsinking in confined under-hood environments. |
| Package | 8-pin SO-EP (exposed pad) - provides 53°C/W θJA and 7°C/W θJC for reliable power dissipation up to 1.509W at +70°C ambient. |
Pinout & Package
MAX15006AASA/V+ is housed in an 8-pin SO-EP (small-outline with exposed thermal pad) package. The exposed pad (EP) is internally connected to GND and must be soldered to the PCB ground plane for optimal thermal performance. Pin 1 is IN; Pin 2 is OUT; Pin 3 is GND; Pins 4–7 are N.C.; Pin 8 is N.C. (FB not used in fixed-output MAX15006A).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Regulator supply input | Accepts 4V–40V unregulated input; requires 0.1μF bypass capacitor to GND for stability and transient immunity. |
| 2 (OUT) | Regulated 3.3V output | Delivers up to 50mA; requires ≥2.2μF low-ESR ceramic capacitor to GND for loop stability across –40°C to +125°C. |
| 3 (GND) | Power and signal ground reference | Common return path for IN, OUT, and internal circuitry; must be connected to low-impedance PCB ground plane. |
| 4–7 (N.C.) | No internal connection | Not bonded or functional; may be left floating or tied to GND for mechanical rigidity-no electrical impact. |
| 8 (N.C.) | No internal connection | Unused pin in MAX15006A; differs from MAX15007C which uses Pin 8 for FB and MAX15007A/B which use Pin 8 for EN. |
| EP (Exposed Pad) | Thermal and electrical ground | Internally tied to GND; soldering to PCB ground improves θJA by ~20°C/W and prevents thermal derating below 1.509W. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 10μA at no load and 90μA at 50mA - enables >10-year battery life in always-on automotive sensors. |
| Automotive-grade thermal range | –40°C to +125°C operation - qualified for under-hood and cabin applications per AEC-Q100 requirements. |
| Load-dump survivability | Withstands 45V transients on IN pin - eliminates need for external TVS diodes in ISO 7637-2 compliant designs. |
| Stable with minimal output capacitance | Operates stably with only 2.2μF ceramic output cap - reduces BOM count and PCB area vs. legacy LDOs requiring ≥10μF. |
| Integrated protection | Short-circuit and thermal shutdown with auto-recovery - prevents latch-up and field failures during wiring faults or overheating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX15006AATT/V+ | Same electrical specs but in 6-pin TDFN-EP package (3mm × 3mm); θJA = 42°C/W vs. 53°C/W for SO-EP. | Better thermal performance and smaller footprint; requires different land pattern and reflow profile. | Select when board space is constrained or higher power density is needed; verify PCB thermal relief design for TDFN EP. |
| TLV73333PDBVR | Lower input range (1.4V–5.5V), 300mA output, 38μA IQ; not automotive-qualified or load-dump rated. | Suitable for consumer or industrial low-voltage applications only-not for 12V automotive battery rails. | Use only in non-automotive 3.3V systems with stable low-voltage input; cannot replace MAX15006AASA/V+ in automotive designs. |
Compared with MAX15006AATT/V+, the MAX15006AASA/V+ offers easier manual inspection and wave-solder compatibility but lower thermal efficiency; compared with TLV73333PDBVR, it delivers automotive robustness and wide-input capability at the cost of lower output current and higher minimum input voltage.

FAQ
What is the maximum input voltage rating for MAX15006AASA/V+?
The MAX15006AASA/V+ has an absolute maximum input voltage of +45V, with continuous operation specified from 4V to 40V. This allows it to withstand ISO 7637-2 Load Dump Pulse 5a (45V, 400ms) without external protection-critical for automotive battery-connected applications where transient suppression is essential.
Does MAX15006AASA/V+ include an enable (EN) pin?
No, MAX15006AASA/V+ does not include an enable input. The EN pin is exclusive to the MAX15007 series (e.g., MAX15007AASA/V+). MAX15006A variants operate continuously when powered; they lack logic-controlled on/off functionality and consume 10μA quiescent current at all times when VIN is applied.
What output capacitor value is required for stable operation of MAX15006AASA/V+?
MAX15006AASA/V+ requires a minimum 2.2μF low-ESR ceramic or tantalum output capacitor connected between OUT and GND for guaranteed stability across –40°C to +125°C. Larger values (e.g., 22μF) further reduce output noise and improve load-transient response, but 2.2μF is the validated minimum for all operating conditions.
Is MAX15006AASA/V+ qualified for automotive use?
Yes, MAX15006AASA/V+ is explicitly automotive-qualified: the "/V" suffix denotes AEC-Q100 compliance, and it is rated for –40°C to +125°C operation with testing per automotive reliability standards. It is designed for under-hood, chassis, and body electronics where extended temperature range and transient robustness are mandatory.
What is the dropout voltage of MAX15006AASA/V+ at full load?
The dropout voltage of MAX15006AASA/V+ is 1000mV (1V) at 50mA output current and +25°C. This means the device maintains regulation as long as VIN remains ≥ 4.3V (3.3V + 1V). Dropout increases slightly at temperature extremes but remains within specification across the full –40°C to +125°C range.
