Product details
Overview
MAX15007BATT+ from Maxim Integrated is an ultra-low quiescent-current, 5V fixed-output 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 (10–18µA min–max), and features an active-high enable input. It is used in tire-pressure monitoring sensors where low standby power and cold-crank operation are critical.
For engineers reviewing the MAX15007BATT+ datasheet, MAX15007BATT+ pinout, MAX15007BATT+ application, or MAX15007BATT+ equivalent, key selection criteria include guaranteed 50mA output under wide VIN (4–40V), 300mV dropout at 50mA, thermal shutdown at +165°C, stable operation with 2.2µF ceramic output capacitor, and automotive-grade −40°C to +125°C operation.
Technical Context
The MAX15007BATT+ integrates a P-channel pass transistor, error amplifier with 1.23V internal reference, thermal sensor, and current-limit circuitry. Its enable logic accepts 0.4V low / 1.4V high thresholds with 60mV hysteresis and internal 0.5µA pulldown - enabling reliable wake-up from deep sleep without external pull-down resistors.
It supports cold-crank operation down to 4V input and withstands 45V load-dump transients. Dropout voltage is specified at 300mV (typ) at 50mA load for the 5V version, and output regulation remains stable across −40°C to +125°C ambient with ±1.5% load regulation (100µA–50mA).
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% - tightly regulated for microcontroller I/O and sensor biasing in automotive modules. |
| Max Output Current | 50mA - sufficient for low-power MCUs, RF transceivers, and analog sensors in TPMS and body electronics. |
| Quiescent Current | 11µA typ (10–18µA) at no load - enables >10-year battery life in always-on vehicle sensors. |
| Dropout Voltage | 300mV at 50mA - ensures regulation down to VIN = 5.3V, critical during engine cranking. |
| Shutdown Current | 3µA typ - reduces system standby power when EN is pulled low. |
| Thermal Shutdown | +165°C with 20°C hysteresis - protects against sustained overload without requiring external thermal management. |
| Package | 6-pin TDFN-EP (3mm × 3mm) - thermally enhanced for 1.904W dissipation at +70°C ambient. |
Pinout & Package
MAX15007BATT+ uses a 6-pin thermally enhanced TDFN-EP package (3mm × 3mm) with exposed pad connected internally to GND. The exposed pad must be soldered to PCB ground plane for optimal thermal performance and EMI suppression.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | IN | Regulator input supply (4–40V); bypass with 0.1µF ceramic capacitor to GND for stability. |
| 3 | GND | Analog/digital ground reference; connects to EP for thermal path and noise control. |
| 4 | EN | Active-high enable input; 0.4V/1.4V logic thresholds with internal 0.5µA pulldown - eliminates need for external pull-down resistor. |
| 5, 6 | OUT | 5V regulated output; requires ≥2.2µF low-ESR ceramic capacitor to GND for stability across temperature and load. |
| EP | Exposed Pad | Internally tied to GND; mandatory connection to PCB ground plane for thermal dissipation and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 11µA typical at no load - extends battery life in always-on automotive sensors beyond 10 years. |
| Enable input with internal pulldown | 0.5µA internal sink eliminates external pull-down resistor, reducing BOM count and layout area. |
| Stable with 2.2µF output capacitor | Enables use of small, low-cost ceramic capacitors instead of larger tantalum types - improves reliability and saves board space. |
| 45V load-dump tolerance | Withstands ISO 7637-2 Pulse 5a transients without external clamping - simplifies front-end protection design. |
| Automotive temperature range | −40°C to +125°C operation with guaranteed specs - qualified for under-hood and wheel-well applications. |
| P-channel pass device | Maintains low quiescent current even at full 50mA load - unlike N-channel LDOs that increase IQ with load. |
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 |
|---|---|---|---|
| LM2936QMM-5.0/NOPB | Higher 25µA IQ (vs. 11µA), 60mA output, SO-8 package only - no TDFN option. | Lacks enable input; not suitable for duty-cycled sensor nodes requiring precise wake/sleep control. | Choose when board space is unconstrained and enable functionality is unnecessary. |
| TPS7B6750QPWPRQ1 | Lower 2.5µA IQ, but 150mA output and higher 45V abs max rating; 5-pin SOT-23 package. | Requires external 100nF–10µF output capacitor; less tolerant of low-ESR ceramic variations than MAX15007BATT+. | Prefer for higher-current loads (>50mA) where ultra-low IQ is primary requirement and footprint allows SOT-23. |
Compared with LM2936QMM-5.0/NOPB and TPS7B6750QPWPRQ1, MAX15007BATT+ uniquely balances ultra-low IQ (11µA), integrated enable with pulldown, TDFN footprint, and guaranteed 50mA output across −40°C to +125°C - making it optimal for space-constrained, battery-sensitive automotive sensing nodes.

FAQ
What is the maximum input voltage the MAX15007BATT+ can withstand without damage?
The MAX15007BATT+ has an absolute maximum input voltage rating of +45V, allowing it to survive automotive load-dump transients per ISO 7637-2 Pulse 5a. Continuous operation is specified from 4V to 40V; operation above 40V is limited to transient events only and must remain within the 45V absolute maximum limit to avoid permanent damage.
Does the MAX15007BATT+ require an external pull-down resistor on the EN pin?
No, the MAX15007BATT+ does not require an external pull-down resistor on the EN pin. It features an internal 0.5µA pulldown current that holds EN low during power-up or when driven by a high-impedance source, ensuring predictable shutdown behavior without additional components.
Can the MAX15007BATT+ operate stably with a 2.2µF ceramic output capacitor over the full temperature range?
Yes, the MAX15007BATT+ is explicitly characterized and guaranteed to remain stable with a minimum 2.2µF ceramic output capacitor across −40°C to +125°C. This specification accounts for worst-case ESR and capacitance drift in X7R dielectrics, eliminating the need for larger or more expensive capacitor types.
What is the dropout voltage of the MAX15007BATT+ at 50mA output current?
The dropout voltage of the MAX15007BATT+ is 300mV (typical) at 50mA output current and +25°C ambient. The datasheet guarantees ≤525mV maximum across −40°C to +125°C, ensuring reliable 5V regulation down to VIN = 5.3V - critical for operation during automotive cold-crank conditions.
Is the MAX15007BATT+ qualified for automotive applications?
Yes, the MAX15007BATT+ is AEC-Q100 qualified and rated for the full automotive temperature range of −40°C to +125°C. Its ordering code suffix "/V+" denotes automotive qualification, and it meets requirements for thermal shutdown, short-circuit protection, and load-dump immunity required in vehicle ECUs and sensors.
