Product details
Overview
MAX15006AATT/V+ from Maxim Integrated is an automotive-grade, 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 a space-saving 6-pin TDFN-EP package - ideal for tire-pressure monitoring sensors and automotive body control modules.
For engineers reviewing the MAX15006AATT/V+ datasheet, MAX15006AATT/V+ pinout, MAX15006AATT/V+ application, or MAX15006AATT/V+ equivalent, this page delivers verified technical context, package-specific pin functions, real-world design meaning of key specs, and two validated alternative parts for automotive power management selection.
Technical Context
The MAX15006AATT/V+ uses an internal p-channel pass device to maintain low quiescent current (10μA at no load, 90μA at 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 stability ensured by a minimum 2.2μF ceramic output capacitor.
No enable input is present - unlike the MAX15007 series - confirming it is a non-enable, always-on regulator variant. Dropout voltage is 1000mV at 50mA (for 3.3V output), enabling operation through cold-crank conditions down to 4V input while sustaining regulated output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - supports direct battery connection in 12V/24V automotive systems, including load dump (45V tolerant) and cold-crank (down to 4V). |
| Output Voltage | Fixed 3.3V ±1.5% - tightly regulated for powering microcontrollers, CAN transceivers, and sensor signal chains requiring stable low-voltage rails. |
| Output Current | Guaranteed 50mA - sufficient for low-power MCUs, RF modules, and analog front-ends in distributed automotive electronics. |
| Quiescent Current | 10μA at no load - enables multi-year battery life in always-on vehicle subsystems like TPMS and door modules. |
| Dropout Voltage | 1000mV at 50mA - ensures regulation remains active during engine cranking when battery dips to ~6V (VIN = 6V → VOUT = 3.3V sustained). |
| Thermal Protection | 165°C shutdown with 20°C hysteresis - prevents permanent damage under sustained overload or poor PCB thermal layout. |
| Package | 6-pin TDFN-EP (3mm × 3mm) - exposed pad enhances thermal performance (θJA = 42°C/W), enabling 1.904W dissipation at +70°C ambient. |
Pinout & Package
MAX15006AATT/V+ is housed in a thermally enhanced 6-pin TDFN-EP (3mm × 3mm) package with exposed pad (EP) internally connected to GND. The EP must be soldered to a PCB ground plane for optimal thermal performance and is not intended as a functional ground terminal.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | IN | Regulator input supply - accepts 4V–40V; requires 0.1μF bypass to GND close to pin for noise immunity and stability. |
| 3 | N.C. | No internal connection - must remain unconnected; floating or tied to GND has no functional impact. |
| 4 | GND | Analog/digital ground reference - connects to system ground plane; ties to EP via PCB copper for thermal conduction. |
| 5, 6 | OUT | Regulated 3.3V output - requires ≥2.2μF low-ESR ceramic capacitor to GND for stability across temperature and load. |
| EP | Exposed Pad | Internally bonded to GND - mandatory connection to PCB ground plane for thermal management; not a signal path. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 10μA at no load enables >10-year battery life in always-on automotive sensors (e.g., TPMS, seat occupancy). |
| Wide input voltage range | 4V–40V operation covers cold-crank (≥4V), nominal 12V/24V, and 45V load-dump transients without external clamping. |
| Stable with small output capacitor | Guaranteed stability with only 2.2μF ceramic output cap - reduces BOM count and board area vs. legacy LDOs requiring ≥10μF. |
| Automotive temperature grade | –40°C to +125°C operation qualified per AEC-Q100 - suitable for under-hood and cabin applications without derating. |
| Integrated protection | Thermal shutdown (165°C) and short-circuit current limit (175mA) prevent field failures in harsh environments. |
Applications
| Tire-Pressure Monitoring System (TPMS) | Automotive Body Control Module (BCM) |
|---|---|

Use Scenario: Provides controlled 3.3V bias to GPS/GNSS receiver and cellular modem during cold-start sequence after vehicle power-up. IC Role / Device Role / Timing Role: Pre-regulator ensuring stable voltage before enabling high-current DC-DC stages - avoids brown-out during inrush. Use Value: Low dropout (1000mV @50mA) maintains regulation even as input decays during capacitor discharge phase of startup. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX15006AASA/V+ | Same 3.3V output, -40°C to +125°C rating, but in 8-pin SO-EP package (θJA = 53°C/W, lower power density). | Preferred where manual assembly, rework, or higher thermal margin is needed; less space-constrained than TDFN. | Select MAX15006AASA/V+ when PCB layout allows larger footprint and thermal design prioritizes ease of soldering over miniaturization. |
| TLV73333PDBVR | 3.3V fixed LDO with 65μA IQ, 200mA output, but only rated to +105°C and max 6.5V input - not automotive-qualified. | Restricted to non-automotive industrial or consumer applications; lacks load-dump/cold-crank robustness. | Choose TLV73333PDBVR only for cost-sensitive, non-automotive designs with <6.5V input and no AEC-Q100 requirement. |
Compared with MAX15006AASA/V+, the MAX15006AATT/V+ offers 22% smaller footprint and 21% better thermal resistance, making it optimal for compact TPMS sensors; versus TLV73333PDBVR, it provides 6.7× lower IQ and full automotive qualification - essential for safety-critical vehicle subsystems.

FAQ
What is the maximum input voltage the MAX15006AATT/V+ can withstand?
The MAX15006AATT/V+ supports continuous operation up to 40V input and can withstand transient load-dump events up to 45V without damage. This capability eliminates the need for external TVS diodes in standard 12V/24V automotive architectures, simplifying design and improving system robustness.
Does the MAX15006AATT/V+ include an enable pin?
No, the MAX15006AATT/V+ does not include an enable input. It is a non-enable variant in the MAX15006 family - unlike the MAX15007 series, which adds EN functionality. The MAX15006AATT/V+ powers up automatically when IN voltage exceeds ~4V and remains active until input is removed.
What output capacitor value is required for stable operation of the MAX15006AATT/V+?
A minimum 2.2μF low-ESR ceramic capacitor is required at the OUT pin for guaranteed stability across –40°C to +125°C and 0–50mA load. 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 the MAX15006AATT/V+ qualified for automotive use?
Yes, the "/V+" suffix explicitly denotes AEC-Q100 qualification. The MAX15006AATT/V+ is rated for –40°C to +125°C operation, undergoes automotive-grade stress testing, and is manufactured in an IATF 16949-certified facility - meeting requirements for under-hood and cabin electronic control units.
How does the MAX15006AATT/V+ handle thermal overload?
When junction temperature exceeds +165°C, the MAX15006AATT/V+ activates thermal shutdown, turning off the pass transistor. After die temperature drops by 20°C (to ~145°C), regulation resumes automatically. This cycling protects against permanent damage during sustained overload or inadequate heatsinking.
