Product details
Overview
MAX15006BATT+T from Maxim Integrated is a 5V 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 10μA no-load ground current, features 300mV dropout at 50mA, and is qualified for -40°C to +125°C operation in a thermally enhanced 6-pin TDFN package.
For engineers reviewing the MAX15006BATT+T datasheet, MAX15006BATT+T pinout, MAX15006BATT+T application, or MAX15006BATT+T equivalent, key selection criteria include cold-crank tolerance, 45V load-dump survivability, stability with 2.2μF ceramic output capacitor, thermal shutdown behavior, and compatibility with space-constrained automotive modules requiring minimal standby power.
Technical Context
The MAX15006BATT+T uses an internal p-channel pass device to maintain low quiescent current across full load (90μA at 50mA), enabling reliable operation during automotive cold-crank (down to 4V) and transient overvoltage events. Its error amplifier compares output against a precision 1.23V reference, delivering tight regulation (±1.5% over temperature and line/load) without external compensation.
Unlike the MAX15007 series, the MAX15006BATT+T lacks an enable (EN) input - it is always-on - simplifying control architecture in systems where continuous regulation is required. Protection includes thermal shutdown at +165°C with 20°C hysteresis and short-circuit current limiting to 175mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1.5% (guaranteed over -40°C to +125°C, 1mA–50mA load) |
| Input Voltage Range | 4V to 40V - supports full automotive battery range including cold-crank (4V) and load dump (45V absolute max) |
| Quiescent Current | 10μA at no load; 90μA at 50mA - enables >10-year battery life in TPMS and remote sensors |
| Dropout Voltage | 300mV at 50mA - ensures regulation down to VIN = 5.3V, critical for low-voltage brownout resilience |
| Output Capacitor | Stable with ≥2.2μF ceramic - eliminates need for large electrolytics, reduces board area and cost |
| Thermal Shutdown | Triggers at +165°C junction temperature with 20°C hysteresis - prevents permanent damage during sustained overload |
| Short-Circuit Current Limit | 175mA - allows indefinite GND short without latch-off, supporting fault-tolerant system design |
Pinout & Package
MAX15006BATT+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 (θJA = 42°C/W).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | IN | Regulator input supply (4V–40V); bypass with 0.1μF ceramic to GND near pin |
| 3 | N.C. | No internal connection - leave unconnected; not usable as signal or ground |
| 4 | GND | Power ground return; connects to EP for thermal path - must tie to main system GND |
| 5, 6 | OUT | Regulated 5V output; requires ≥2.2μF low-ESR ceramic capacitor to GND for stability |
| EP | Exposed Pad | Internally tied to GND; mandatory thermal interface - solder to ≥1in² copper pour |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 10μA no-load enables >10-year shelf life in battery-backed automotive modules |
| Load-dump survivability | Withstands 45V transients per ISO 7637-2 - eliminates need for upstream TVS in many designs |
| Cold-crank operation | Regulates continuously down to 4V input - maintains ECU power during engine start |
| Minimal external components | Requires only two capacitors (0.1μF IN, 2.2μF OUT) - reduces BOM count and layout complexity |
| Automotive-grade reliability | Qualified to -40°C to +125°C ambient; built on BiCMOS process for robustness in harsh environments |
Applications
| Tire-Pressure Monitoring System (TPMS) | Automotive Body Control Module (BCM) |
|---|---|

IC Role / Device Role / Timing Role: Secondary regulated source decoupled from main power domain for noise-sensitive RF sections. Use Value: Low output noise (179µVRMS) minimizes phase noise in GPS L1 band; stable with 2.2μF ceramic avoids tantalum reliability concerns. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX15006BASA+ | Same 5V output, identical electrical specs, but in 8-pin SO-EP package (53°C/W θJA) | Better suited for through-hole prototyping or higher-power dissipation needs (>1.5W) | Select when thermal margin is constrained and PCB real estate permits larger footprint |
| TLV73350PDBVR | 5V fixed, 300mA output, 38μA IQ, 350mV dropout at 300mA, SOT-23-5 package | Higher current capability but lower input voltage rating (up to 5.5V only) | Choose only for low-voltage (<6V) systems needing higher output current - not suitable for automotive 12V/24V rails |
Compared with MAX15006BASA+, the MAX15006BATT+T offers superior thermal performance in compact layouts; compared with TLV73350PDBVR, it supports full automotive voltage range but delivers lower output current - making it purpose-built for ultra-low-power, high-reliability 12V/24V subsystems.

FAQ
What is the maximum input voltage the MAX15006BATT+T can withstand?
The MAX15006BATT+T has an absolute maximum input voltage rating of +45V, allowing it to survive automotive load-dump transients per ISO 7637-2. Its operational input range is 4V to 40V, and it remains fully functional across this span while maintaining 5V output regulation and thermal protection.
Does the MAX15006BATT+T include an enable (EN) pin?
No, the MAX15006BATT+T does not have an enable input. It is an always-on regulator - unlike the MAX15007BATT+T variant, which includes an active-high EN pin. The MAX15006BATT+T starts regulating as soon as valid input voltage is applied to the IN pin.
What output capacitor value is required for stable operation of the MAX15006BATT+T?
The MAX15006BATT+T is stable with a minimum 2.2μF low-ESR ceramic output capacitor. Larger values (e.g., 22μF) further improve load-transient response and PSRR. X7R dielectrics are recommended to ensure capacitance retention across -40°C to +125°C.
How does thermal shutdown work in the MAX15006BATT+T?
The MAX15006BATT+T activates thermal shutdown at +165°C junction temperature, turning off the pass transistor. After cooling by 20°C (to ~+145°C), it automatically resumes regulation. This cycling protects the device during sustained overload but requires proper PCB thermal design - especially via the exposed pad - to avoid premature triggering.
Is the MAX15006BATT+T qualified for automotive applications?
Yes, the MAX15006BATT+T is AEC-Q100 qualified and specified for -40°C to +125°C ambient operation. Its construction, testing, and packaging (TDFN-EP with RoHS-compliant finish) meet automotive reliability standards for use in body electronics, chassis, and powertrain-adjacent modules.
