Product details
Overview
MAX15007AATT+ from Maxim Integrated is a 3.3V fixed-output, ultra-low quiescent-current linear regulator designed for automotive and battery-powered systems. It operates from 4V to 40V input, delivers up to 50mA output current, consumes only 11μA typical ground current at no load, features an active-high enable (EN) input, and is qualified for -40°C to +125°C operation in a 6-pin TDFN-EP package.
For engineers reviewing the MAX15007AATT+ datasheet, MAX15007AATT+ pinout, MAX15007AATT+ application, or MAX15007AATT+ equivalent, key selection criteria include its 3.3V fixed output, 3μA shutdown current, 300mV dropout at 50mA (for 5V variants; 1000mV for 3.3V), thermal/short-circuit protection, and compatibility with 2.2μF ceramic output capacitors.
Technical Context
The MAX15007AATT+ integrates a p-channel pass device enabling ultra-low quiescent current across full load (93μA typ at 50mA) and zero-load (11μA typ) conditions. Its internal 1.23V reference and error amplifier regulate output via EN-controlled FET driver logic, supporting cold-crank (4V min) and 45V load-dump survival.
Unlike the MAX15006 series, the MAX15007AATT+ includes an enable input that forces shutdown with 3μA supply current, while maintaining guaranteed 50mA output current, thermal shutdown at +165°C (20°C hysteresis), and short-circuit protection without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - supports wide automotive battery range including cold-crank (4V) and load-dump (45V absolute max). |
| Output Voltage | Fixed 3.3V ±1.5% - tightly regulated for MCU, sensor, and CAN transceiver power rails. |
| Max Output Current | 50mA - sufficient for low-power microcontrollers, RF modules, and analog sensors. |
| Quiescent Current | 11μA typ at no load - enables >10-year battery life in always-on tire-pressure monitoring systems. |
| Shutdown Current | 3μA typ - enables deep-sleep modes in automotive body electronics without parasitic drain. |
| Dropout Voltage | 1000mV at 50mA - defines minimum VIN–VOUT margin required to maintain regulation at full load for 3.3V output. |
| Thermal Shutdown | +165°C with 20°C hysteresis - protects against sustained overload or poor PCB heatsinking in engine bay applications. |
| Package | 6-pin TDFN-EP (3mm × 3mm) - thermally enhanced footprint with exposed pad for 9°C/W junction-to-case resistance. |
Pinout & Package
MAX15007AATT+ uses a 6-pin thermally enhanced TDFN-EP package (3mm × 3mm) with exposed pad connected internally to GND. The package supports high-power dissipation (1904mW at +70°C) and requires soldering the EP to PCB ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 - IN | Regulator input supply | Accepts 4V–40V; bypassed with 0.1μF capacitor to GND for stability and noise rejection. |
| 3 - GND | Ground reference | Primary return path for load and internal circuitry; connects to EP for thermal conduction. |
| 4 - EN | Active-high enable | Drives high (>1.4V) to activate regulator; internally pulled down (0.5μA) for default shutdown. |
| 5, 6 - OUT | Regulated output | Delivers 3.3V; requires ≥2.2μF low-ESR ceramic capacitor to GND for loop stability. |
| EP - Exposed Pad | Thermal & electrical ground | Internally tied to GND; must be soldered to PCB ground plane to achieve θJC = 9°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 11μA typical at no load ensures multi-year operation from coin-cell or vehicle battery in standby. |
| Enable-controlled shutdown | 3μA shutdown current and logic-level EN allow precise system-level power sequencing and sleep control. |
| Automotive-grade thermal robustness | -40°C to +125°C operation with +165°C thermal shutdown enables under-hood deployment. |
| Load-dump and cold-crank tolerance | Withstands 45V transient and regulates down to 4V input-critical for 12V automotive electrical systems. |
| Minimal external components | Stable with only two capacitors (0.1μF IN, 2.2μF OUT); no compensation network required. |
| Short-circuit protected output | 175mA current limit and automatic thermal recovery prevent damage during wiring faults or ESD events. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX15007AASA+ | Same 3.3V output, EN input, and specs-but in 8-pin SO-EP package (larger footprint, higher θJA = 53°C/W). | Better suited for prototyping or manual assembly due to SO package; lower power density than TDFN. | Select when board space allows larger package or thermal management relies on airflow rather than PCB copper. |
| TLV73333PDBVR | 3.3V fixed LDO with 65μA IQ (vs. 11μA), 300mA output (vs. 50mA), 1.7V–5.5V input (vs. 4V–40V), no EN pin. | Targeted at low-voltage consumer/portable apps-not automotive or high-input-voltage use cases. | Choose only for cost-sensitive, non-automotive designs where input stays below 5.5V and quiescent current <11μA is not required. |
Compared with MAX15007AASA+, the MAX15007AATT+ offers 27% smaller footprint and superior thermal performance (θJA = 42°C/W vs. 53°C/W); compared with TLV73333PDBVR, it provides 5.8× lower quiescent current and 8× wider input range-making it irreplaceable for automotive battery-supplied systems.

FAQ
What is the maximum input voltage the MAX15007AATT+ can withstand without damage?
The MAX15007AATT+ has an absolute maximum input voltage rating of +45V. While normal operation is specified from 4V to 40V, the device is designed to survive automotive load-dump transients up to 45V without latch-up or permanent damage-confirmed per ISO 7637-2 Pulse 5a testing requirements.
Does the MAX15007AATT+ require an external feedback resistor network?
No. The MAX15007AATT+ is the fixed 3.3V variant and does not use the FB pin. Its output is internally set; the FB pin is left unconnected (N.C.) in this version. Only MAX15007C variants require external resistors for adjustable output.
Can the MAX15007AATT+ operate reliably at -40°C ambient temperature?
Yes. The MAX15007AATT+ is fully specified and tested over -40°C to +125°C ambient temperature. Electrical characteristics-including 3.3V output accuracy, 11μA quiescent current, and 50mA output capability-are guaranteed across this full automotive temperature range.
What is the purpose of the exposed pad (EP) on the MAX15007AATT+ package?
On the MAX15007AATT+, the exposed pad (EP) is internally connected to GND and serves dual purposes: it provides the primary thermal conduction path (θJC = 9°C/W) from die to PCB, and acts as a low-inductance ground connection. It must be soldered to a dedicated PCB ground plane-floating or unconnected EP degrades thermal performance and may cause instability.
How does the enable (EN) pin behave when left unconnected on the MAX15007AATT+?
When left unconnected, the EN pin on the MAX15007AATT+ is actively pulled down internally by a 0.5μA current source, forcing the device into shutdown mode with only 3μA supply current. No external pull-down resistor is needed-this feature simplifies design and ensures fail-safe power-off behavior.
