Product details
Overview
MAX15007BASA+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, and features an active-high enable (EN) pin. It is used in tire-pressure monitoring sensors where low-power always-on operation and cold-crank resilience are critical.
For engineers reviewing the MAX15007BASA+T datasheet, MAX15007BASA+T pinout, MAX15007BASA+T application, or MAX15007BASA+T equivalent, key selection criteria include guaranteed 50mA output under wide VIN (4–40V), 3μA shutdown current, thermal/short-circuit protection, -40°C to +125°C operation, and compatibility with 2.2μF ceramic output capacitors.
Technical Context
The MAX15007BASA+T integrates a p-channel pass device enabling ultra-low quiescent current across full load (93μA typ at 50mA) and zero-load (11μA typ) conditions. Its internal 1.23V reference and error amplifier regulate output via EN-controlled FET driver, with thermal shutdown triggered at +165°C and 20°C hysteresis.
It supports automotive cold-crank (operation down to 4V) and withstands 45V load dump transients. The fixed 5.0V ±2.5% output is specified over -40°C to +125°C, with dropout voltage of 300mV at 50mA (VIN ≥ VOUT + 300mV), ensuring stable regulation even during transient brownouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - Enables direct connection to automotive battery rails including cold-crank (4V) and load-dump (45V tolerant) conditions. |
| Output Voltage | 5.0V ±2.5% - Fixed, factory-trimmed output suitable for powering microcontrollers, sensors, and CAN transceivers without external feedback. |
| Max Output Current | 50mA - Guaranteed continuous output under worst-case thermal conditions (TA ≤ +125°C, TDFN package). |
| Quiescent Current | 11μA typ at no load - Minimizes standby power loss in always-on automotive modules like TPMS. |
| Shutdown Current | 3μA typ - Achieved via EN pin; enables deep-sleep mode for extended battery life in remote sensing nodes. |
| Dropout Voltage | 300mV at 50mA - Ensures regulation stability when input drops to 5.3V, critical for engine-off battery operation. |
| Operating Temp | -40°C to +125°C - Qualified for under-hood automotive applications per AEC-Q100 stress requirements. |
Pinout & Package
MAX15007BASA+T is packaged in an 8-pin SO-EP (Small Outline with Exposed Pad), thermally enhanced RoHS-compliant package. The exposed pad (EP) must be soldered to PCB ground plane for optimal thermal performance (θJA = 53°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Regulator input supply | Accepts 4–40V; requires 0.1μF bypass capacitor to GND for stability and noise rejection. |
| 2 (OUT) | Regulated 5V output | Delivers up to 50mA; requires ≥2.2μF low-ESR ceramic capacitor to GND for loop stability. |
| 3 (GND) | Power and signal ground | Reference node for all internal circuitry; connects to EP for thermal conduction. |
| 4 (N.C.) | No connection | Not internally bonded; must remain unconnected on PCB to avoid parasitic coupling. |
| 5 (N.C.) | No connection | Not internally bonded; must remain unconnected on PCB. |
| 6 (N.C.) | No connection | Not internally bonded; must remain unconnected on PCB. |
| 7 (EN) | Active-high enable input | Drives high (>1.4V) to enable regulation; internally pulled down (0.5μA) for default shutdown. |
| 8 (N.C.) | No connection | Not internally bonded; must remain unconnected on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 11μA typical at no load ensures >10-year battery life in TPMS sensors powered by CR2032 cells. |
| Enable-controlled shutdown | 3μA shutdown current and logic-level EN allow host MCU to gate power to peripheral circuits on demand. |
| Automotive-grade thermal protection | +165°C shutdown with 20°C hysteresis prevents latch-up during sustained overload or high ambient conditions. |
| Stable with minimal output capacitance | Guaranteed stability with only 2.2μF ceramic output capacitor simplifies BOM and reduces board area. |
| Load-dump and cold-crank robustness | Withstands 45V transients and operates down to 4V input, meeting ISO 7637-2 Pulse 5a and SAE J1113-11 requirements. |
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 |
|---|---|---|---|
| LM2936QMM-5.0/NOPB | Fixed 5V output, 50μA IQ, no enable pin, SO-8 package | Lacks EN control and ultra-low IQ; higher ground current increases standby power | Choose when enable functionality is unnecessary and cost sensitivity outweighs battery life requirements. |
| TPS7B6750QDDARQ1 | 5V fixed, 28μA IQ, integrated EN, wettable flank SO-8, AEC-Q100 Grade 1 | Higher IQ than MAX15007BASA+T but offers enhanced manufacturability (wettable flanks) and Grade 1 qualification | Prefer for new automotive designs requiring automated optical inspection (AOI) compatibility and broader temperature margin (–40°C to +150°C). |
Compared with LM2936QMM-5.0/NOPB and TPS7B6750QDDARQ1, MAX15007BASA+T provides the lowest quiescent current (11μA) and highest load-dump immunity (45V), making it optimal for ultra-long-life, harsh-environment automotive sensing-though it lacks wettable flanks and Grade 1 extended temperature support.

FAQ
What is the maximum input voltage rating for MAX15007BASA+T?
The MAX15007BASA+T has an absolute maximum input voltage rating of +45V, and operates continuously from 4V to 40V. This allows it to survive automotive load-dump transients (ISO 7637-2 Pulse 5a) while maintaining regulation down to cold-crank voltages as low as 4V - a key requirement for under-hood applications where battery voltage sags during engine start.
Does MAX15007BASA+T require an external feedback resistor network?
No, MAX15007BASA+T does not require an external feedback network. It is a fixed 5.0V output variant (MAX15007B) with internal resistor divider and reference. Unlike the MAX15007C adjustable version, pins FB and EN are functionally separate - EN controls on/off state, while FB is unused and left unconnected in this part.
What is the thermal shutdown behavior of MAX15007BASA+T?
MAX15007BASA+T activates thermal shutdown at +165°C junction temperature and remains off until junction temperature falls by 20°C (to +145°C), providing hysteresis to prevent oscillation. During sustained overload, this results in pulsed output - a fail-safe mechanism that protects the IC and downstream circuitry without requiring external intervention.
Can MAX15007BASA+T be used with ceramic output capacitors smaller than 2.2μF?
No - MAX15007BASA+T requires a minimum 2.2μF low-ESR ceramic output capacitor for guaranteed stability across -40°C to +125°C. Using smaller values risks oscillation or poor transient response. X7R dielectrics are recommended; ensure worst-case capacitance (e.g., at -40°C and rated voltage) stays above 1.3μF to maintain phase margin.
Is MAX15007BASA+T qualified to AEC-Q100 standards?
Yes, MAX15007BASA+T carries the "/V" suffix option (e.g., MAX15007BASA/V+) for automotive qualification. While the base MAX15007BASA+T is built on the same die and process, official AEC-Q100 Grade 0 qualification (-40°C to +150°C) applies only to /V-marked variants. For production automotive use, specify MAX15007BASA/V+ to ensure full qualification documentation and traceability.
