Product details
Overview
MAX15007CATT+T from Maxim Integrated is an ultra-low quiescent-current adjustable linear regulator designed for automotive and battery-powered systems. It operates from 4V to 40V input, delivers up to 50mA output current, consumes only 9µA typical ground current at no load, features an enable input (EN), and supports 1.8V–10V adjustable output via external feedback resistors. It is used in tire-pressure monitoring sensors where low standby power and cold-crank operation are critical.
For engineers reviewing the MAX15007CATT+T datasheet, MAX15007CATT+T pinout, MAX15007CATT+T application, or MAX15007CATT+T equivalent, key selection criteria include its 3µA shutdown current, 300mV dropout at 50mA, thermal shutdown at +165°C, compatibility with 2.2µF ceramic output capacitors, and AEC-Q100-qualified 6-pin TDFN-EP package for harsh environments.
Technical Context
The MAX15007CATT+T integrates a p-channel pass transistor, precision 1.23V bandgap reference, error amplifier, and active-high enable logic. Its feedback (FB) pin accepts a resistive divider to set output voltage between 1.8V and 10V, with FB input current ≤±100nA and threshold tolerance of ±2.4% over temperature.
It employs internal thermal shutdown (trip at +165°C, hysteresis 20°C) and short-circuit protection (175mA current limit). The device sustains operation during cold-crank (down to 4V) and withstands 45V load-dump transients without external clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - supports full automotive battery range including cold-crank (4V) and load dump (40V) |
| Output Current | Guaranteed 50mA - sufficient for microcontroller biasing, sensor signal conditioning, and CAN transceiver VCC in TPMS modules |
| Quiescent Current | 9µA typical at no load - enables >10-year battery life in always-on automotive sensors |
| Shutdown Current | 3µA typical - reduces system standby power when EN is pulled low |
| Dropout Voltage | 300mV at 50mA - maintains regulation down to VIN = VOUT + 0.3V, critical for low-input-voltage operation |
| Output Accuracy | ±2.4% over -40°C to +125°C - ensures stable MCU core voltage across full automotive temperature range |
| Thermal Shutdown | +165°C with 20°C hysteresis - protects against sustained overload in enclosed ECUs without derating |
Pinout & Package
MAX15007CATT+T uses a thermally enhanced 6-pin TDFN-EP (3mm × 3mm) package with exposed pad connected internally to GND. The package is RoHS-compliant and qualified per AEC-Q100 Grade 1 (-40°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 - IN | Regulator supply input | Accepts 4V–40V; requires 0.1µF bypass to GND; withstands 45V transient |
| 3 - GND | Ground reference | Power and signal return; connects to EP for thermal conduction |
| 4 - EN | Active-high enable input | Pulled down internally (0.5µA); drives high to enable regulator; tolerates up to 40V |
| 5 - OUT | Regulated output | Delivers up to 50mA; requires ≥2.2µF low-ESR ceramic capacitor to GND for stability |
| 6 - FB | Feedback voltage sense | Sets output via resistor divider; references 1.23V ±2.4%; draws ≤±100nA |
| EP - Exposed Pad | Thermal and electrical ground | Must be soldered to PCB ground plane; not usable as primary GND connection |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable Output Range | 1.8V to 10V via external resistor divider - enables single BOM for multiple rail voltages in multi-sensor modules |
| Ultra-Low Quiescent Current | 9µA typical at no load - minimizes battery drain in always-on telematics and TPMS nodes |
| Enable-Controlled Shutdown | 3µA shutdown current with EN = low - allows host MCU to gate power to peripheral ICs on demand |
| Stable with Small Capacitor | Works with 2.2µF ceramic output cap - reduces board area and cost vs. larger tantalum alternatives |
| Automotive Transient Robustness | Withstands 45V load dump and operates down to 4V - eliminates need for external TVS or pre-regulator in 12V systems |
Applications
| Tire-Pressure Monitoring System (TPMS) | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar adjustable LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73318PDBVR | Fixed 1.8V output; no FB pin; 250mA output; 30µA IQ; SOT-23-5 package | Not adjustable; higher output current but lacks programmability and automotive temp range | Select only if fixed 1.8V rail and higher current are required; not suitable for variable-voltage designs |
| TPS7B8733QKVURQ1 | Fixed 3.3V output; 40V input; 500mA output; 28µA IQ; thermal foldback; wettable flank QFN | Higher current and integrated fault reporting; no adjustability; larger footprint | Prefer for high-current 3.3V rails needing diagnostics; MAX15007CATT+T remains optimal for low-IQ adjustable use cases |
Compared with TLV73318PDBVR and TPS7B8733QKVURQ1, the MAX15007CATT+T uniquely combines ultra-low 9µA quiescent current, 1.8V–10V adjustability, and AEC-Q100 qualification in a space-constrained 3mm × 3mm TDFN - making it irreplaceable for battery-sensitive, multi-rail automotive sensors.

FAQ
What is the maximum input voltage the MAX15007CATT+T can withstand?
The MAX15007CATT+T has an absolute maximum input voltage rating of +45V. It is designed to survive automotive load-dump transients up to this level without damage or latch-up, provided proper input capacitance and layout practices are followed. Its operational input range remains 4V to 40V for guaranteed regulation performance.
Does the MAX15007CATT+T require an external feedback resistor network?
Yes, the MAX15007CATT+T requires an external resistive divider between OUT, FB, and GND to set the output voltage within 1.8V–10V. The FB pin references a precise 1.23V ±2.4% internal bandgap, and the divider must supply ≥5µA for stability. No resistor network is needed for fixed-output variants like MAX15007AATT+T.
What is the thermal performance of the MAX15007CATT+T in its TDFN package?
The MAX15007CATT+T in the 6-pin TDFN-EP package has a junction-to-ambient thermal resistance (θJA) of 42°C/W and junction-to-case (θJC) of 9°C/W when mounted on a 4-layer PCB with 1in² copper pour under the exposed pad. At TA = +70°C, it dissipates up to 1904mW before derating begins.
Can the MAX15007CATT+T be used without connecting the EN pin?
Yes. The EN pin of the MAX15007CATT+T is internally pulled down with a 0.5µA current. Leaving EN unconnected places the device in shutdown mode (3µA IQ). To enable operation, EN must be driven high - either by a GPIO or directly tied to IN. Floating EN is not recommended for active operation.
Is the MAX15007CATT+T qualified for automotive applications?
Yes, the MAX15007CATT+T is AEC-Q100 Grade 1 qualified (-40°C to +125°C) and manufactured in an automotive-grade flow. Its datasheet specifies guaranteed performance across this full temperature range, including thermal shutdown, load regulation, and dropout behavior - confirming suitability for under-hood and chassis-mounted automotive systems.
