Product details
Overview
MAX15006BATT+ 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 6-pin TDFN-EP package. It is used in tire-pressure monitoring sensors where low standby power and cold-crank resilience are critical.
For engineers reviewing the MAX15006BATT+ datasheet, MAX15006BATT+ pinout, MAX15006BATT+ application, or MAX15006BATT+ equivalent, key selection criteria include guaranteed 50mA load capability under wide VIN, 10μA quiescent current at zero load, thermal shutdown at +165°C, stable operation with 2.2μF ceramic output capacitor, and compatibility with 45V load-dump transients in automotive environments.
Technical Context
The MAX15006BATT+ uses an internal p-channel pass device to maintain ultra-low quiescent current across full load (90μA at 50mA) and over temperature (-40°C to +125°C). Its regulation loop references a 1.23V internal bandgap, enabling precise 5.0V ±2.5% output tolerance over line, load, and temperature.
Unlike the MAX15007 series, this variant lacks an enable (EN) input - it is always-on. It supports cold-crank operation down to 4V input and withstands 45V transient load dumps without latch-up or damage, making it suitable for unregulated automotive battery rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±2.5% (guaranteed over -40°C to +125°C, 1mA–50mA load) |
| Input Voltage Range | 4V to 40V - supports direct connection to automotive battery including cold-crank (4V) and load-dump (45V absolute max) |
| Quiescent Current | 10μA at no load - enables >10-year battery life in TPMS and similar always-on sensor nodes |
| Dropout Voltage | 300mV at 50mA - ensures regulation down to VIN = 5.3V, critical for low-voltage brownout conditions |
| Output Current | Guaranteed 50mA continuous - sufficient to power microcontrollers, RF transceivers, and analog sensors in compact modules |
| Thermal Protection | Shuts down at +165°C junction temperature with 20°C hysteresis - prevents permanent damage during sustained overload |
| Package Thermal Resistance | θJA = 42°C/W (TDFN-EP) - enables 1.9W dissipation at +70°C ambient, supporting high VIN–VOUT differentials |
Pinout & Package
MAX15006BATT+ is housed in a thermally enhanced 6-pin TDFN-EP (3mm × 3mm) package with exposed pad (EP) internally connected to GND. The EP must be soldered to PCB ground plane for optimal thermal performance and EMI suppression.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | IN | Regulator input - accepts 4V–40V; requires 0.1μF bypass to GND close to pin |
| 3 | N.C. | No internal connection - must remain unconnected; not usable as ground or signal |
| 4 | GND | Analog/digital ground reference - connects to system GND and EP via low-inductance path |
| 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 connection to PCB ground plane for thermal and electrical integrity |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 10μA at no load and 90μA at full 50mA load - minimizes battery drain in always-on automotive sensors |
| Wide input voltage range | 4V to 40V operation - accommodates automotive battery fluctuations from cold-crank to load dump |
| Low-dropout architecture | 300mV dropout at 50mA - maintains regulation even when input drops to 5.3V |
| Minimal external components | Stable with only 0.1μF input and 2.2μF output ceramic capacitors - reduces BOM count and board area |
| Robust protection suite | Integrated short-circuit current limit (175mA), thermal shutdown (+165°C), and 45V transient tolerance - eliminates need for external protection circuitry |
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 |
|---|---|---|---|
| MAX15006BASA+ | Same 5V output, identical electrical specs, but in 8-pin SO-EP package (larger footprint, higher θJA = 53°C/W) | Better suited for through-hole prototyping or legacy SO layouts; lower power density than TDFN | Select when board space allows larger package or thermal margin is less constrained |
| TLV73350PDBVR | 5V fixed LDO with 65μA IQ, 300mA output, 1.4V–5.5V input - not automotive-qualified, lower voltage range, higher IQ | Limited to non-automotive industrial or consumer use; cannot survive cold-crank or load-dump stress | Consider only for cost-sensitive, non-automotive applications where 40V input and -40°C rating are unnecessary |
Compared with MAX15006BASA+, the MAX15006BATT+ offers 27% lower thermal resistance and 30% smaller footprint; compared with TLV73350PDBVR, it provides automotive qualification, 40V input support, and 6.5× lower quiescent current - essential for battery longevity in harsh environments.

FAQ
What is the maximum input voltage the MAX15006BATT+ can withstand?
The MAX15006BATT+ has an absolute maximum input voltage rating of +45V, allowing it to survive automotive load-dump transients without damage. Its operational input range is 4V to 40V, and it remains functional during cold-crank events down to 4V. This makes the MAX15006BATT+ suitable for direct connection to unregulated vehicle battery rails where voltage spikes and dips are common.
Does the MAX15006BATT+ include an enable (EN) pin?
No, the MAX15006BATT+ does not include an enable input. It is an always-on regulator - unlike the MAX15007BATT+ variant, which features an active-high EN pin. The MAX15006BATT+ starts regulating as soon as valid input voltage is applied to the IN pin and remains active until power is removed. This simplifies design in applications requiring unconditional power delivery.
What output capacitor value is required for stable operation of the MAX15006BATT+?
The MAX15006BATT+ requires a minimum 2.2μF low-ESR ceramic or tantalum output capacitor connected between OUT and GND for stable operation across -40°C to +125°C and up to 50mA load. Larger values (e.g., 22μF) improve load-transient response and PSRR. X7R dielectrics are recommended to maintain ≥1.3μF capacitance under worst-case temperature and bias conditions.
Is the MAX15006BATT+ qualified for automotive applications?
Yes, the MAX15006BATT+ is rated for the full automotive temperature range of -40°C to +125°C and is offered in a RoHS-compliant, lead(Pb)-free TDFN-EP package. While not explicitly AEC-Q100 certified in the public datasheet, its specifications, test conditions, and packaging align with automotive-grade requirements - including 45V transient tolerance, thermal shutdown, and robust construction for under-hood deployment.
How much power can the MAX15006BATT+ dissipate in its TDFN package?
The MAX15006BATT+ in the 6-pin TDFN-EP package has a continuous power dissipation rating of 1904mW at +70°C ambient, derating linearly by 23.8mW/°C above that temperature. At +125°C ambient, its allowable dissipation drops to 596mW. This thermal performance enables reliable 50mA output even with high VIN–VOUT differentials - for example, 26V input to 5V output yields ~1.1W dissipation, well within safe limits at moderate ambient temperatures.
