Product details
Overview
MAX15007BATT/V+ from Maxim Integrated is an automotive-grade, ultra-low quiescent-current linear regulator with fixed 5V output, 4V–40V input range, 50mA output capability, 300mV dropout at 50mA, and active-high enable (EN) input. It operates across –40°C to +125°C and targets always-on battery systems in tire-pressure monitoring and automotive body electronics.
For engineers reviewing the MAX15007BATT/V+ datasheet, MAX15007BATT/V+ pinout, MAX15007BATT/V+ application, or MAX15007BATT/V+ equivalent, key selection criteria include shutdown current (3μA), cold-crank operation, 45V load-dump tolerance, thermal shutdown at +165°C, and compatibility with 2.2μF ceramic output capacitors.
Technical Context
The MAX15007BATT/V+ integrates a p-channel pass device enabling ultra-low ground current (11μA typ at no load, 93μA typ at 50mA) while maintaining regulation through automotive cold-crank conditions (VIN down to 4V). Its internal 1.23V reference and error amplifier drive the pass FET to regulate output voltage with ±1.5% load regulation over 100μA–50mA.
Enable logic features 0.4V low threshold and 1.4V high threshold with 60mV hysteresis; EN withstands up to +45V and is internally pulled down with 0.5μA current. Thermal protection activates at +165°C with 20°C hysteresis, and short-circuit current limit is 175mA.
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 (45V absolute max). |
| Output Voltage | Fixed 5.0V ±2.5% - guaranteed 4.925V–5.075V at 1mA across –40°C to +125°C. |
| Quiescent Current | 11μA typ at no load; 93μA typ at 50mA - enables >10-year battery life in TPMS and remote sensors. |
| Shutdown Current | 3μA typ - reduces system standby power when EN is low. |
| Dropout Voltage | 300mV max at 50mA - ensures regulation down to VIN = 5.3V, critical for low-input automotive operation. |
| Thermal Shutdown | +165°C activation with +20°C hysteresis - protects against sustained overload without external circuitry. |
| Output Capacitor | Stable with ≥2.2μF ceramic - eliminates need for large electrolytics; supports compact PCB layout. |
Pinout & Package
MAX15007BATT/V+ is housed in a thermally enhanced 6-pin TDFN-EP (3mm × 3mm) package with exposed pad connected to GND. The package delivers 1.904W power dissipation at TA = +70°C and θJA = 42°C/W.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | IN | Regulator input supply (4V–40V); requires 0.1μF bypass to GND for stability. |
| 3 | GND | Power and signal ground reference; connects to exposed pad for thermal conduction. |
| 4 | EN | Active-high enable input; 0.4V/1.4V logic thresholds; internally pulled down (0.5μA) for default-off safety. |
| 5, 6 | OUT | Regulated 5V output; requires ≥2.2μF low-ESR ceramic capacitor to GND for stability and transient response. |
| EP | Exposed Pad | Internally tied to GND; must be soldered to PCB ground plane to achieve rated thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low shutdown current | 3μA typical - extends battery life in always-off vehicle subsystems such as door modules and occupancy sensors. |
| Load-dump survival | Withstands 45V transients - eliminates need for upstream TVS diodes in 12V automotive systems. |
| Cold-crank operation | Regulates down to VIN = 4V - maintains MCU power during engine cranking without brownout. |
| Thermally enhanced TDFN | 42°C/W junction-to-ambient - enables 50mA output at +125°C ambient without heatsink. |
| Internal short-circuit protection | 175mA current limit with auto-recovery - prevents latch-up during wiring faults or ESD events. |
Applications
| Tire-Pressure Monitoring System (TPMS) | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | Lower IQ (250nA), lower max VIN (5.5V), no load-dump tolerance, SOT-23-5 package. | Suitable for low-voltage portable electronics only; not rated for automotive transients or temperature range. | Select only for non-automotive, <6V systems where ultra-low IQ outweighs robustness requirements. |
| LM2936QMM-5.0/NOPB | Higher IQ (15μA), 40V max VIN, no enable pin, SOIC-8 package, 600mV dropout at 50mA. | Lacks EN control and cold-crank margin; requires larger output cap (10μF) for stability. | Choose when enable functionality is unnecessary and board space allows SOIC-8; verify dropout margin at 4V input. |
Compared with TLV73350PDBVR and LM2936QMM-5.0/NOPB, MAX15007BATT/V+ uniquely combines automotive qualification (/V), 3μA shutdown, 45V transient tolerance, and 300mV dropout - making it the only option for reliable 5V regulation in harsh-temperature, always-on automotive nodes.

FAQ
What is the maximum input voltage the MAX15007BATT/V+ can withstand during load dump events?
The MAX15007BATT/V+ is rated to withstand 45V transients on its IN pin, as specified in Absolute Maximum Ratings. This allows direct connection to automotive 12V battery rails without external TVS protection during standardized ISO 7637-2 load-dump pulses. Operation above 40V is limited to transient conditions only; continuous operation must remain within 4V–40V.
Does the MAX15007BATT/V+ require an external feedback resistor network to set its output voltage?
No. The MAX15007BATT/V+ has a factory-trimmed fixed 5.0V output and does not use the FB pin. The FB terminal is a no-connect (N.C.) for this variant. Only MAX15007C variants require external resistors to configure adjustable outputs from 1.8V to 10V.
How does the enable (EN) pin behave when left unconnected on the MAX15007BATT/V+?
When EN is left unconnected, the internal 0.5μA pulldown current pulls it to GND, placing the MAX15007BATT/V+ into shutdown mode with 3μA supply current. To activate regulation, EN must be driven high (≥1.4V) - either by a GPIO or directly tied to IN for always-on operation.
Can the MAX15007BATT/V+ deliver 50mA continuously at +125°C ambient temperature?
Yes - when mounted on a PCB with adequate copper area (≥1 in² connected to EP), the MAX15007BATT/V+ in TDFN package can sustain 50mA at +125°C ambient with VIN = 14V and VOUT = 5V. Derating curves in the datasheet confirm ≥26mA at VIN = 26V, confirming full 50mA capability under typical automotive conditions.
Is the MAX15007BATT/V+ qualified to AEC-Q100 standards?
Yes. The "/V" suffix in MAX15007BATT/V+ explicitly denotes automotive qualification per AEC-Q100 Rev H, including stress testing across –40°C to +125°C, ESD, latch-up, and reliability validation. This is confirmed in Maxim's ordering information and package marking data.
