Product details
Overview
MAX15006CATT+ from Maxim Integrated is an ultra-low quiescent-current adjustable linear regulator designed for automotive and battery-powered systems. It operates from 4V to 40V input, delivers up to 50mA output current, consumes only 8–15µA no-load ground current, and supports 1.8V–10V adjustable output via external feedback divider. It is used in tire-pressure monitoring sensors where cold-crank resilience and low standby power are critical.
For engineers reviewing the MAX15006CATT+ datasheet, MAX15006CATT+ pinout, MAX15006CATT+ application, or MAX15006CATT+ equivalent, key selection criteria include guaranteed 50mA load capability under -40°C to +125°C, 300mV dropout at 50mA, thermal shutdown at +165°C, stable operation with 2.2µF ceramic output capacitor, and compatibility with 45V load-dump transients.
Technical Context
The MAX15006CATT+ implements a p-channel pass transistor architecture enabling ultra-low quiescent current across full load (90µA at 50mA) and temperature (-40°C to +125°C). Its internal 1.23V reference and error amplifier regulate output voltage via external FB resistor divider, supporting precise 1.8V–10V adjustment with ±0.5% typical FB threshold accuracy.
Unlike fixed-output variants, the MAX15006CATT+ omits enable logic and EN pin-confirmed by its pinout (IN, OUT, GND, N.C., N.C., EP) and absence of EN function in MAX15006C ordering table. It features integrated short-circuit protection (175mA limit) and thermal shutdown with 20°C hysteresis, ensuring robustness in automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - supports automotive cold-crank (down to 4V) and 45V load-dump survival without external clamping. |
| Output Current | Guaranteed 50mA - sufficient for microcontroller biasing, sensor signal conditioning, and CAN transceiver VCC in TPMS modules. |
| Quiescent Current | 8–15µA at no load - enables >10-year battery life in always-on vehicle sensors with low duty-cycle wakeups. |
| Dropout Voltage | 300mV at 50mA - allows regulation down to VIN = VOUT + 0.3V, critical for maintaining 3.3V rail during 5V battery sag. |
| Output Accuracy | ±1.5% over temp - ensured by 1.23V ±2.4% FB reference and low-TC resistive divider design. |
| Thermal Protection | Shuts down at +165°C junction, restarts at +145°C - prevents permanent damage during sustained overload or poor PCB heatsinking. |
| Stability | Stable with ≥2.2µF ceramic output capacitor - eliminates need for large tantalum or electrolytic caps, reducing board area and cost. |
Pinout & Package
MAX15006CATT+ uses a thermally enhanced 6-pin TDFN-EP (3mm × 3mm) package with exposed pad connected internally to GND. The package supports 1.904W dissipation at +70°C ambient and requires soldering the EP to PCB ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 - IN | Regulator supply input | Accepts 4V–40V; must be bypassed with 0.1µF ceramic capacitor to GND for noise immunity and stability. |
| 3 - GND | Ground reference | Primary return path for load and internal circuitry; connects to EP for thermal conduction. |
| 4 - N.C. | No connection | Not internally bonded; must remain unconnected per datasheet to avoid parasitic coupling. |
| 5, 6 - OUT | Regulated output | Delivers 1.8V–10V (set by FB divider); requires ≥2.2µF low-ESR ceramic capacitor to GND for loop stability. |
| EP - Exposed Pad | Thermal & electrical ground | Internally tied to GND; must be soldered to ≥1in² copper pour for thermal management and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable output (1.8V–10V) | Enables single BOM reuse across multiple system rails (e.g., 3.3V MCU core, 5V analog, 9V actuator interface) using external R1/R2 divider. |
| Ultra-low ground current (8–15µA) | Reduces battery drain in always-on applications like TPMS; achieves >10-year shelf life with CR2032 coin cell. |
| 45V load-dump tolerance | Withstands ISO 7637-2 Pulse 5a without external TVS, simplifying front-end protection in automotive body electronics. |
| Low dropout (300mV @ 50mA) | Maintains regulation during engine cranking (battery dip to ~6V), ensuring uninterrupted operation of safety-critical sensors. |
| Thermal shutdown with hysteresis | Prevents thermal runaway in enclosed enclosures; automatic recovery at +145°C avoids manual reset requirement. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar adjustable linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2936QML-SD/NOPB | Fixed 3.3V/5V only; no adjustable option; 15µA IQ; 40V max input; SO-8 only | Lacks FB pin and output adjustability; requires separate part numbers per voltage | Select when fixed output suffices and SO-8 footprint is preferred over TDFN. |
| TPS7B8133QPWRQ1 | Adjustable (1.2V–5.5V); 25µA IQ; 40V max input; 300mV dropout at 150mA; 6-pin WSON | Higher IQ and lower max output voltage limit; rated for AEC-Q100 Grade 1 only (−40°C to +125°C) | Select when higher output current (150mA) is needed and 10µA extra IQ is acceptable. |

FAQ
What output voltage range does the MAX15006CATT+ support?
The MAX15006CATT+ supports an adjustable output voltage from 1.8V to 10V, set by an external resistive divider connected between OUT, FB (pin 5), and GND. Its internal 1.23V feedback reference ensures accurate regulation across the full range, with typical FB threshold tolerance of ±2.4%. This flexibility allows a single MAX15006CATT+ design to replace multiple fixed-output regulators in multi-rail systems.
Does the MAX15006CATT+ include an enable (EN) pin?
No, the MAX15006CATT+ does not include an enable pin. It is part of the MAX15006 series (not MAX15007), and its pinout-IN, OUT, GND, N.C., N.C., EP-confirms the absence of EN functionality. Enable logic is exclusive to MAX15007 variants (e.g., MAX15007CATT+). The MAX15006CATT+ operates continuously when powered within its 4V–40V input range.
What is the maximum continuous output current of the MAX15006CATT+?
The MAX15006CATT+ guarantees 50mA of continuous output current across its full operating temperature range (−40°C to +125°C) and input voltage range (4V to 40V), provided thermal limits are respected. Its 6-pin TDFN-EP package dissipates up to 1.904W at +70°C ambient, and derating curves in the datasheet confirm 50mA is sustainable at +125°C ambient with VIN = 26V and VOUT = 3.3V.
Can the MAX15006CATT+ withstand automotive load-dump transients?
Yes, the MAX15006CATT+ withstands 45V load-dump transients per ISO 7637-2 Pulse 5a without external protection components. Its absolute maximum input rating is +45V, and its internal p-channel pass device and robust process design allow direct connection to unclamped battery rails in automotive applications such as TPMS and BCM subsystems.
What output capacitor is required for stable operation of the MAX15006CATT+?
The MAX15006CATT+ requires a minimum 2.2µF low-ESR ceramic output capacitor connected between OUT and GND for stable operation across −40°C to +125°C and up to 50mA load. X7R dielectrics are recommended to maintain capacitance stability over temperature. Larger values (e.g., 22µF) further improve PSRR and transient response but are not required for basic stability.
