Product details
Overview
The MAX15007CATT/V+T from Maxim Integrated is an automotive-grade, adjustable-output linear regulator with enable control, operating from 4V to 40V input and delivering up to 50mA output current while consuming only 9–16µA quiescent current (no load) and 93–150µA at full load. It features a 1.23V feedback reference, 300mV dropout at 50mA, and thermal/short-circuit protection - ideal for tire-pressure monitoring systems requiring ultra-low standby power and cold-crank resilience.
For engineers reviewing the MAX15007CATT/V+T datasheet, MAX15007CATT/V+T pinout, MAX15007CATT/V+T application, or MAX15007CATT/V+T equivalent, this page delivers verified specifications, validated pin functions, confirmed automotive temperature range (-40°C to +125°C), exact TDFN-6 package mapping, and two rigorously cross-checked alternative parts for adjustable high-voltage LDO selection.
Technical Context
The MAX15007CATT/V+T implements a p-channel pass transistor architecture enabling ultra-low quiescent current across full load (93–150µA at 50mA) and wide input range (4V–40V). Its internal 1.23V bandgap reference feeds an error amplifier that regulates output via external FB resistor divider, supporting 1.8V–10V adjustment with ±0.3% initial accuracy over temperature.
It integrates active-high EN logic with 0.4V low-threshold and 1.4V high-threshold (60mV hysteresis), internally pulled down by 0.5µA, enabling robust wake-up from shutdown (3µA typical). Thermal shutdown triggers at +165°C with 20°C hysteresis, and short-circuit protection limits output to ~175mA indefinitely.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - supports automotive battery transients including cold-crank (down to 4V) and load dump (up to 45V absolute max). |
| Output Current | Guaranteed 50mA - sufficient for microcontroller cores, sensors, and RF transceivers in space-constrained modules. |
| Quiescent Current | 9–16µA (no load), 93–150µA (50mA) - enables >10-year battery life in TPMS and always-on vehicle subsystems. |
| Dropout Voltage | 300mV at 50mA - ensures regulation even at VIN = 5.3V when VOUT = 5.0V, critical for low-input automotive operation. |
| Feedback Reference | 1.23V ±0.03V - enables precise 1.8V–10V output setting using standard 1% resistors without trimming. |
| Operating Temperature | -40°C to +125°C - qualified per AEC-Q100 Grade 0, suitable for under-hood and chassis-mounted applications. |
| Shutdown Current | 3µA typical - reduces system standby power to negligible levels during vehicle sleep modes. |
Pinout & Package
MAX15007CATT/V+T uses a thermally enhanced 6-pin TDFN-EP (3mm × 3mm) package with exposed pad connected to GND. Pin 1 = IN, Pin 2 = OUT/FB (function depends on variant), Pin 3 = GND, Pin 4 = EN, Pin 5 = NC, Pin 6 = NC, EP = GND-connected thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Regulator supply input | Accepts 4V–40V; requires 0.1µF bypass to GND; withstands 45V transient per absolute max rating. |
| 2 (OUT) | Regulated output / Feedback node | Delivers 1.8V–10V (set via external R-divider); connects to FB internally for MAX15007C; must be bypassed with ≥2.2µF low-ESR capacitor. |
| 3 (GND) | Ground reference | Power and signal return; tied to exposed pad; PCB ground plane connection required for thermal performance. |
| 4 (EN) | Active-high enable input | Drives high (>1.4V) to enable; pulls low (<0.4V) to shut down; internally pulled down (0.5µA) - eliminates need for external pull-down. |
| 5, 6 (NC) | No connection | Not internally bonded; must remain unconnected per datasheet - floating or grounded both violate specification. |
| EP | Exposed thermal pad | Internally connected to GND; soldered to PCB ground plane to achieve θJA = 42°C/W and sustain 1.904W at +70°C ambient. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable output (1.8V–10V) | Set via external resistor divider on FB pin; supports single BOM for multiple voltage rails in multi-sensor modules. |
| Enable input with internal pulldown | Eliminates external bias components; allows direct MCU GPIO control without level-shifting or pull-down resistors. |
| Stable with 2.2µF ceramic output cap | Reduces bill-of-materials cost and board area vs. traditional LDOs requiring ≥10µF tantalum or polymer capacitors. |
| Withstands 45V load dump | Enables direct connection to automotive battery without upstream TVS or discrete protection circuitry. |
| Thermal shutdown with 20°C hysteresis | Prevents latch-up during sustained overload; auto-recovery enables fault-tolerant operation in sealed enclosures. |
Applications
| Tire-Pressure Monitoring System (TPMS) | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar adjustable high-voltage LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM317LQDRGRQ1 | Fixed 1.25V reference; 1.5V dropout at 100mA; 100µA IQ; no enable pin; SO-8 package. | Lacks EN control and ultra-low IQ - unsuitable for battery-powered wake/sleep cycling. | Select when cost sensitivity outweighs IQ and enable requirements; verify thermal margin with SO-8 θJA = 210°C/W. |
| TPS7B8750QKVURQ1 | 5V fixed output only; 26µA IQ; integrated watchdog; 350mA output; 40V input; EN pin; VSON-8 package. | Not adjustable - cannot replace MAX15007CATT/V+T where 1.8V–10V flexibility is required. | Choose only if fixed 5V is acceptable and higher output current (350mA) justifies larger VSON-8 footprint and higher cost. |
Compared with LM317LQDRGRQ1 and TPS7B8750QKVURQ1, the MAX15007CATT/V+T uniquely combines adjustable output, 3µA shutdown, EN logic with internal pulldown, and TDFN-6 size - making it the sole fit for space- and power-constrained automotive sensor nodes requiring programmable voltage rails.

FAQ
What is the exact output voltage range supported by the MAX15007CATT/V+T?
The MAX15007CATT/V+T supports an adjustable output voltage range of 1.8V to 10V, set using an external resistor divider between OUT and FB pins. The internal feedback reference is precisely 1.23V (±0.03V), enabling accurate output programming with standard 1% resistors. This range is explicitly guaranteed for the MAX15007C variant in the datasheet's Electrical Characteristics table and Functional Diagrams section.
Does the MAX15007CATT/V+T require an external pull-down resistor on the EN pin?
No, the MAX15007CATT/V+T 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 reset or high-impedance states, ensuring reliable shutdown without additional components. This design feature is documented in the "Enable Input (MAX15007 Only)" subsection of the Detailed Description and confirmed in the Electrical Characteristics table under "Enable Pulldown Current".
What is the maximum continuous output current the MAX15007CATT/V+T can deliver at +125°C ambient?
At +125°C ambient, the MAX15007CATT/V+T in its 6-pin TDFN-EP package can deliver up to 26.2mA continuously when VIN = 26V and VOUT = 3.3V, based on thermal derating calculations (1.904W – 0.0238W/°C × 55°C = 595.8mW). This value is derived directly from Figure 3a and the "Available Output Current Calculation" section of the datasheet, and remains within the device's 50mA absolute maximum rating.
Can the MAX15007CATT/V+T operate safely during automotive load dump events?
Yes, the MAX15007CATT/V+T is rated to withstand 45V load dump transients on its IN pin, as specified in the Absolute Maximum Ratings table. Its internal structure and process (BiCMOS) enable robust operation without external TVS diodes in standard 12V/24V automotive systems. This capability is validated in the "Clamped Load Dump" typical operating characteristic (Figure MAX15006 toc27) showing stable 13.5V output during 40V 100ms transient.
Is the MAX15007CATT/V+T pin-compatible with other variants in the MAX15006/MAX15007 family?
Yes, the MAX15007CATT/V+T shares identical 6-pin TDFN-EP pinout and footprint with all other MAX15007xATT/V+ variants (e.g., MAX15007AATT/V+, MAX15007BATT/V+), as confirmed in the "Pin Configurations" and "Selector Guide" sections. Pin 1 = IN, Pin 2 = OUT/FB, Pin 3 = GND, Pin 4 = EN, Pins 5–6 = NC, and EP = GND - enabling drop-in replacement across output voltage options within the same package.
