Product details
Overview
MAX15006AATT/V+T 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, 10μA no-load ground current, and operation over –40°C to +125°C. It delivers stable power in battery-backed automotive modules such as tire-pressure monitoring sensors where low standby consumption and cold-crank resilience are critical.
For engineers reviewing the MAX15006AATT/V+T datasheet, MAX15006AATT/V+T pinout, MAX15006AATT/V+T application, or MAX15006AATT/V+T equivalent, key selection factors include its 3.3V fixed output, TDFN-EP package thermal performance, dropout voltage behavior at full load, enable logic compatibility (absent in MAX15006 series), and automotive qualification per AEC-Q100.
Technical Context
The MAX15006AATT/V+T uses a p-channel pass transistor architecture to maintain ultra-low quiescent current across load conditions-10μA at no load and 90μA at 50mA. Its internal 1.23V reference and error amplifier regulate output with ±1.5% load regulation and 0.25% line regulation over 6V–35V input.
It features integrated thermal shutdown (trip at +165°C, 20°C hysteresis) and short-circuit protection (175mA current limit), enabling robust operation in harsh automotive environments. The device lacks an enable input-distinguishing it from the MAX15007 family-and relies on direct VIN control for on/off sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - supports wide automotive battery transients including cold-crank (down to 4V) and load dump (up to 45V absolute max). |
| Output Voltage | Fixed 3.3V ±1.5% - tightly regulated for MCU core/logic supply in automotive microcontrollers and sensors. |
| Quiescent Current | 10μA at no load - enables >10-year battery life in always-on TPMS and telematics modules. |
| Max Output Current | 50mA - sufficient for low-power microcontrollers, CAN transceivers, and analog front-ends. |
| Dropout Voltage | 1000mV at 50mA - defines minimum headroom needed between VIN and VOUT for regulation at full load. |
| Operating Temp | –40°C to +125°C - qualified for under-hood and chassis-mounted automotive applications. |
| Package | 6-pin TDFN-EP (3mm × 3mm) - thermally enhanced layout with exposed pad for 9°C/W junction-to-case resistance. |
Pinout & Package
MAX15006AATT/V+T is housed in a 3mm × 3mm, 6-pin thermally enhanced TDFN-EP package with exposed pad (EP) internally connected to GND. The EP must be soldered to 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 capacitor to GND for stability. |
| 3 | N.C. | No internal connection - must remain unconnected; floating or tied to GND has no effect. |
| 4 | GND | Power and signal ground reference - connects to system ground plane and EP for thermal path. |
| 5, 6 | OUT | Regulated 3.3V output - requires ≥2.2μF low-ESR ceramic capacitor to GND for loop stability. |
| EP | Exposed Pad | Internally tied to GND - mandatory solder connection to PCB ground pour for thermal dissipation (θJC = 9°C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 10μA at no load enables multi-year operation from coin-cell or small Li-ion batteries in always-on systems. |
| Wide input voltage range | 4V–40V accommodates 12V/24V automotive systems through cold-crank (4V) and load-dump (45V transient) events. |
| Stable with minimal output capacitance | Guaranteed stability with only 2.2μF ceramic output capacitor simplifies BOM and reduces board area. |
| Automotive temperature grade | –40°C to +125°C operation ensures reliability in engine bay, transmission, and chassis-mounted electronics. |
| Integrated protection | Thermal shutdown (+165°C trip, 20°C hysteresis) and short-circuit current limiting (175mA) prevent damage during fault conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX15007AATT/V+ | Includes active-high EN input; same 3.3V output, 4V–40V input, and 50mA rating; 3μA shutdown current. | Required when system-level power sequencing or remote ON/OFF control is needed. | Select MAX15007AATT/V+ if enable functionality is required; otherwise MAX15006AATT/V+ offers simpler, lower-cost implementation. |
| TPS7B6733QPWPRQ1 | 3.3V fixed LDO with 3.5μA IQ, 40V max input, 150mA output, and integrated enable; AEC-Q100 Grade 1 (–40°C to +125°C). | Higher output current and lower IQ suit more demanding automotive nodes; different pinout and package (HTSSOP-8). | Choose TPS7B6733QPWPRQ1 for higher current or lower IQ needs; verify PCB layout compatibility due to different footprint and enable logic. |
Compared with MAX15007AATT/V+, MAX15006AATT/V+ eliminates enable circuitry for cost-sensitive, always-on designs; versus TPS7B6733QPWPRQ1, it trades higher IQ and lower current capability for smaller TDFN footprint and proven field reliability in TPMS deployments.

FAQ
What is the maximum input voltage rating for MAX15006AATT/V+T?
The MAX15006AATT/V+T supports an absolute maximum input voltage of +45V, with continuous operation specified from 4V to 40V. This allows reliable function during automotive load-dump events (typically 40V–45V for 400ms) and cold-crank conditions down to 4V. Operation beyond 40V is limited to transient conditions only and must comply with Absolute Maximum Ratings.
Does MAX15006AATT/V+T include an enable input?
No, MAX15006AATT/V+T does not include an enable input. It is part of the MAX15006 family, which lacks EN functionality. Enable capability is exclusive to the MAX15007 series (e.g., MAX15007AATT/V+). MAX15006AATT/V+T operates continuously when valid input voltage is applied to the IN pin.
What output capacitor is required for stable operation of MAX15006AATT/V+T?
MAX15006AATT/V+T requires a minimum 2.2μF low-ESR ceramic or tantalum output capacitor connected between OUT and GND. X7R dielectric is recommended for stable capacitance across –40°C to +125°C. Larger values (e.g., 22μF) improve PSRR and transient response but are not required for basic stability.
Is MAX15006AATT/V+T qualified for automotive applications?
Yes, MAX15006AATT/V+T is automotive-qualified with the "/V" suffix indicating AEC-Q100 compliance. It operates over the full –40°C to +125°C junction temperature range and is packaged in a thermally enhanced 6-pin TDFN-EP suitable for under-hood and chassis-mounted automotive electronics.
What is the dropout voltage of MAX15006AATT/V+T at full load?
The dropout voltage of MAX15006AATT/V+T is 1000mV (1V) at 50mA output current and +25°C. This value increases with temperature and decreases slightly at lighter loads. At 5mA, dropout is typically 100mV, enabling efficient operation near minimum input voltage.
