Product details
Overview
MAX15006BASA+ 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 an 8-pin SO-EP package.
For engineers reviewing the MAX15006BASA+ datasheet, MAX15006BASA+ pinout, MAX15006BASA+ application, or MAX15006BASA+ equivalent, key selection considerations include its guaranteed 50mA load capability under cold-crank conditions, 45V load-dump tolerance, stable operation with only 2.2μF output capacitance, and thermal shutdown protection at +165°C junction temperature.
Technical Context
The MAX15006BASA+ uses an internal p-channel pass device to maintain low quiescent current across full load (90μA at 50mA) and wide input range (4V–40V). Its regulation architecture relies on a 1.23V internal reference and error amplifier, with output voltage accuracy of ±1.5% over temperature and load.
No enable input is present - unlike the MAX15007 series - making it a permanently enabled regulator. It lacks FB pin functionality, confirming fixed 5V output without external feedback, and integrates short-circuit protection with 175mA current limiting and automatic thermal cycling at +165°C.
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 automotive cold-crank (down to 4V) and withstands 45V load dump transients |
| Quiescent Current | 10μA at no load; 90μA at 50mA - enables >10-year battery life in always-on vehicle modules |
| Dropout Voltage | 300mV at 50mA - allows regulation down to VIN = 5.3V, critical for low-input automotive operation |
| Output Current | Guaranteed 50mA continuous - sufficient for powering microcontrollers, sensors, and CAN transceivers |
| Thermal Protection | Shuts down at +165°C junction temperature with 20°C hysteresis - prevents permanent damage during overload |
| Package | 8-pin SO-EP (exposed pad) - provides 1.509W power dissipation at +70°C ambient, θJA = 53°C/W |
Pinout & Package
MAX15006BASA+ is housed in an 8-pin SO-EP (small-outline, exposed pad) package. The exposed pad is internally connected to GND and must be soldered to the PCB ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Regulator input supply | Accepts 4V–40V; requires 0.1μF bypass capacitor to GND for stability |
| 2 (OUT) | Regulated output | Delivers fixed 5V; requires ≥2.2μF low-ESR ceramic/tantalum capacitor to GND |
| 3 (N.C.) | No connection | Not internally bonded - leave unconnected; no electrical function |
| 4 (N.C.) | No connection | Not internally bonded - leave unconnected; no electrical function |
| 5 (GND) | Power ground reference | Primary ground return path; connects to exposed pad internally |
| 6 (N.C.) | No connection | Not internally bonded - leave unconnected; no electrical function |
| 7 (N.C.) | No connection | Not internally bonded - leave unconnected; no electrical function |
| 8 (N.C.) | No connection | Not internally bonded - leave unconnected; no electrical function |

IC Role / Device Role / Timing Role: Primary voltage regulator converting wide-range industrial DC supply (12–36V) to stable 5V logic rail. Use Value: 4V–40V input range accommodates unregulated field wiring; thermal shutdown protects against enclosure overheating. | Use Scenario: Supplies auxiliary 5V rail for USB hub controller, display backlight driver, or audio codec in head unit. IC Role / Device Role / Timing Role: Secondary LDO providing noise-isolated 5V domain isolated from noisy main 12V supply. Use Value: Low 179µV RMS output noise (at 5V/50mA) minimizes interference in sensitive audio paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX15006BATT+ | Same 5V output, identical electrical specs, but in 6-pin TDFN-EP package (3mm × 3mm) | Requires smaller PCB footprint and offers lower θJA (42°C/W) for higher power density designs | Select when board space is constrained or thermal performance demands lower junction-to-ambient resistance |
| TLV73350PDBVR | 5V fixed LDO with 65μA IQ, 300mA output, 250mV dropout at 300mA - higher current, higher IQ, not automotive-qualified | Lacks AEC-Q100 qualification, 40V max input, and load-dump tolerance - unsuitable for direct automotive replacement | Consider only for non-automotive, cost-sensitive, high-current applications where extended temperature range is not required |
Compared with MAX15006BATT+, the MAX15006BASA+ offers identical regulation performance but in a larger SO-EP package better suited for manual assembly and thermal mass in high-ambient environments; compared with TLV73350PDBVR, it delivers automotive reliability and ultra-low IQ at the expense of output current headroom.

FAQ
What is the maximum input voltage the MAX15006BASA+ can withstand during load-dump events?
The MAX15006BASA+ is rated to withstand 45V transient events on the IN pin without damage or functional interruption, complying with ISO 7637-2 Pulse 5a load-dump requirements common in 12V automotive systems. This eliminates the need for external TVS diodes in many implementations, simplifying design and reducing BOM count while maintaining robustness.
Does the MAX15006BASA+ have an enable (EN) pin?
No, the MAX15006BASA+ does not include an enable input. It is a permanently enabled regulator - unlike the MAX15007B series, which adds EN functionality. All eight pins on the MAX15006BASA+ are either IN, OUT, GND, or no-connect; EN functionality is exclusive to MAX15007 variants. Therefore, MAX15006BASA+ begins regulating as soon as valid input voltage is applied.
What output capacitor value is required for stable operation of the MAX15006BASA+?
The MAX15006BASA+ requires a minimum 2.2μF low-ESR ceramic or tantalum output capacitor connected between OUT and GND for guaranteed stability across -40°C to +125°C and 0–50mA load. Larger values (e.g., 22μF) further reduce output noise and improve load-transient response, but 2.2μF is the validated minimum for all operating conditions specified in the MAX15006BASA+ datasheet.
Is the MAX15006BASA+ qualified for automotive applications?
Yes, the MAX15006BASA+ is explicitly qualified for automotive use with operation over -40°C to +125°C ambient temperature and compliance with AEC-Q100 stress testing requirements. Its datasheet specifies automotive temperature range, load-dump tolerance, and thermal shutdown behavior - all essential for under-hood and chassis-mounted applications where reliability under harsh conditions is mandatory.
What is the dropout voltage of the MAX15006BASA+ at full 50mA load?
The dropout voltage of the MAX15006BASA+ is 300mV (typical) at 50mA load and +25°C, with a maximum of 525mV over temperature and process variation. This means the device maintains regulation as long as VIN remains ≥5.3V (5.0V + 0.3V), enabling reliable operation during automotive cold-crank when battery voltage dips to ~4V - provided sufficient headroom is maintained via system-level design.
