Product details
Overview
MAX15007BATT+T 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 11μA typical ground current at no load, features an active-high enable input (EN), and is qualified for -40°C to +125°C operation in a 6-pin TDFN-EP package.
For engineers reviewing the MAX15007BATT+T datasheet, MAX15007BATT+T pinout, MAX15007BATT+T application, or MAX15007BATT+T equivalent, key selection criteria include its 5V fixed output, 3μA shutdown current, 300mV dropout at 50mA, thermal/short-circuit protection, and compatibility with 2.2μF ceramic output capacitors in space-constrained automotive modules.
Technical Context
The MAX15007BATT+T integrates a p-channel pass device enabling ultra-low quiescent current across full load (93μA typ at 50mA) and shutdown (3μA typ). Its internal 1.23V reference and error amplifier regulate output via EN-controlled FET driver, supporting cold-crank (4V min) and 45V load-dump survival.
Unlike the MAX15006 series, the MAX15007BATT+T includes dedicated EN logic with 0.4V/1.4V thresholds, 60mV hysteresis, and internal 0.5μA pulldown-enabling reliable low-power sequencing in always-on vehicle subsystems without external pull-down resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - supports wide automotive battery range including cold-crank (4V) and load-dump (45V absolute max) |
| Output Voltage | Fixed 5.0V ±2.5% - tightly regulated for MCU, sensor, and CAN transceiver power rails |
| Max Output Current | 50mA - sufficient for low-power microcontrollers and analog front-ends in tire-pressure sensors |
| Quiescent Current | 11μA typ at no load - enables >10-year battery life in always-on monitoring systems |
| Shutdown Current | 3μA typ - reduces system standby power when EN is pulled low |
| Dropout Voltage | 300mV at 50mA - maintains regulation down to VIN = 5.3V, critical during engine cranking |
| Thermal Protection | +165°C shutdown with 20°C hysteresis - prevents damage under sustained overload or poor PCB heatsinking |
Pinout & Package
Package: 6-pin TDFN-EP (3mm × 3mm, exposed pad), RoHS-compliant, automotive-qualified (-40°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 - IN | Regulator supply input | Accepts 4V–40V; requires 0.1μF bypass to GND; withstands 45V transient |
| 3 - GND | Ground reference | Primary return path; connects to exposed pad for thermal conduction |
| 4 - EN | Active-high enable | Logic-level control: <0.4V = shutdown, >1.4V = on; internally pulled down |
| 5, 6 - OUT | Regulated 5V output | Delivers up to 50mA; requires ≥2.2μF low-ESR ceramic capacitor to GND |
| EP - Exposed Pad | Thermal & electrical ground | Must be soldered to PCB ground plane; not used as signal ground connection |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 11μA typical at no load enables multi-year battery operation in TPMS and remote sensors |
| Enable input with internal pulldown | Eliminates need for external pull-down resistor, simplifying BOM and layout in always-on systems |
| Stable with 2.2μF output capacitor | Reduces component count and board area vs. regulators requiring ≥10μF tantalum |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX15007BASA+ | Same 5V output, EN, and specs but in 8-pin SO-EP package (larger footprint, higher θJA = 53°C/W) | Better suited for prototyping or high-vibration environments where larger leaded package improves mechanical reliability | Select when thermal margin is sufficient and SO package simplifies hand-soldering or rework |
| TLV73350PDBVR | 5V fixed LDO with 65μA IQ (vs. 11μA), 300mA output, no load-dump tolerance, rated only to +105°C | Targeted at consumer/portable electronics-not qualified for automotive ambient or transients | Consider only for non-automotive industrial designs where lower cost and higher current outweigh quiescent current and ruggedness needs |
Compared with MAX15007BASA+, the MAX15007BATT+T offers superior thermal performance (θJA = 42°C/W) and smaller footprint; compared with TLV73350PDBVR, it provides automotive-grade transient immunity, extended temperature range, and 3.7× lower quiescent current-critical for battery longevity in harsh environments.

FAQ
What is the maximum input voltage the MAX15007BATT+T can withstand?
The MAX15007BATT+T has an absolute maximum input voltage rating of +45V, allowing it to survive ISO 7637-2 Load Dump Pulse 5a transients common in 12V and 24V automotive systems without external protection components. Its operational input range is 4V to 40V, ensuring functionality during cold-crank (as low as 4V) and normal battery conditions.
Does the MAX15007BATT+T require an external feedback resistor network?
No, the MAX15007BATT+T does not require external feedback resistors because it is the fixed 5V output variant (MAX15007B). Unlike the adjustable MAX15007C version, the MAX15007BATT+T uses internal resistor division to set VOUT = 5.0V; the FB pin is not connected and must remain unconnected or floating in this configuration.
How does the enable (EN) pin function on the MAX15007BATT+T?
The EN pin on the MAX15007BATT+T is an active-high logic input with 0.4V low threshold and 1.4V high threshold (60mV hysteresis). When pulled above 1.4V, the regulator powers up with ~0.4ms startup time; when pulled below 0.4V or left open, the internal 0.5μA pulldown forces shutdown, reducing supply current to 3μA typical. EN tolerates up to 45V, enabling direct connection to VIN for always-on operation.
Can the MAX15007BATT+T drive a 50mA load across the full -40°C to +125°C temperature range?
Yes, the MAX15007BATT+T guarantees 50mA output current across its full -40°C to +125°C operating temperature range, provided the power dissipation remains within limits. At TA = +125°C and VIN = 26V, the TDFN package supports ~26mA continuous output; however, at lower ambient temperatures or reduced VIN–VOUT differential, full 50mA is achievable-verified per Figures 3a and 6a in the datasheet.
What type of output capacitor is recommended for stable operation of the MAX15007BATT+T?
A minimum 2.2μF low-ESR ceramic capacitor (X5R or X7R dielectric) is required between OUT and GND for stable operation across -40°C to +125°C. The MAX15007BATT+T is optimized for small ceramics-no electrolytic or tantalum capacitors are needed. For improved noise suppression and load-transient response, 22μF ceramic capacitors are supported and do not compromise stability.
