Product details
Overview
MAX15006BASA+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 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+T datasheet, MAX15006BASA+T pinout, MAX15006BASA+T application, or MAX15006BASA+T equivalent, key selection criteria include cold-crank tolerance, 45V load-dump withstand capability, thermal shutdown behavior, stability with 2.2μF ceramic output capacitor, and compatibility with high-temperature automotive PCB layouts.
Technical Context
The MAX15006BASA+T uses an internal p-channel pass device to maintain low quiescent current across full load (90μA at 50mA). Its error amplifier compares output voltage against a 1.23V internal reference, enabling precise 5.0V regulation (±1.5% over temperature and line/load) without external feedback components.
Unlike the MAX15007 series, this variant lacks an enable (EN) input and is not shutdown-capable - it remains active whenever VIN is within specification. Protection includes thermal shutdown at +165°C with 20°C hysteresis and short-circuit current limiting to ~175mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1.5% over −40°C to +125°C, 1mA–50mA load, 6V–35V input |
| Input Voltage Range | 4V to 40V - supports automotive cold-crank (≥4V) and load-dump transients (withstands 45V) |
| Quiescent Current | 10μA typical at no load; 90μA at 50mA - enables >10-year battery life in always-on sensors |
| Dropout Voltage | 300mV at 50mA - allows regulation down to VIN = 5.3V, critical for low-input automotive scenarios |
| Output Current | Guaranteed 50mA continuous - sufficient for MCU cores, CAN transceivers, or sensor signal chains |
| Thermal Shutdown | Triggers at +165°C junction temperature with 20°C hysteresis - prevents permanent damage during sustained overload |
| Package Thermal Resistance | θJA = 53°C/W (SO-EP) - requires ≥1 in² copper pour for full 50mA at +125°C ambient |
Pinout & Package
MAX15006BASA+T is housed in an 8-pin SO-EP (Small Outline with Exposed Pad) package, thermally enhanced for automotive use. The exposed pad (EP) must be soldered to PCB ground plane to achieve rated power dissipation (1.509W at +70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Regulator input supply | Accepts 4V–40V; bypass with 0.1μF ceramic to GND near pin; withstands 45V transient |
| 2 (OUT) | Regulated 5V output | Delivers up to 50mA; requires ≥2.2μF low-ESR ceramic capacitor to GND for stability |
| 3 (GND) | Power and signal ground | Reference for all internal circuitry; connects to EP internally; must tie to system ground plane |
| 4 (N.C.) | No connection | Not bonded; leave unconnected - no routing or stitching required |
| 5 (N.C.) | No connection | Not bonded; leave unconnected - no routing or stitching required |
| 6 (N.C.) | No connection | Not bonded; leave unconnected - no routing or stitching required |
| 7 (N.C.) | No connection | Not bonded; leave unconnected - no routing or stitching required |
| 8 (N.C.) | No connection | Not bonded; leave unconnected - no routing or stitching required |
Key Features
| Feature | Design Value |

FAQ
What is the maximum input voltage the MAX15006BASA+T can withstand during load-dump events?
The MAX15006BASA+T is explicitly rated to withstand 45V load-dump transients per ISO 7637-2, as confirmed in its Absolute Maximum Ratings table. This capability eliminates the need for external TVS diodes in many automotive designs, reducing BOM cost and board area. The device sustains this stress while maintaining functional integrity and does not require derating of output current during such events.
Does the MAX15006BASA+T include an enable (EN) pin for power sequencing?
No, the MAX15006BASA+T does not include an enable input. It is a non-shutdown variant in the MAX15006 family. Only MAX15007-series parts (e.g., MAX15007BASA+) feature the EN pin. The MAX15006BASA+T powers on automatically when VIN rises above 4V and remains active until VIN drops below UVLO threshold - making it ideal for always-on applications like TPMS.
What output capacitor value is required for stable operation of the MAX15006BASA+T?
The MAX15006BASA+T requires a minimum 2.2μF low-ESR ceramic or tantalum capacitor from OUT to GND for stable operation across −40°C to +125°C and 0–50mA load. X7R dielectrics are recommended. Larger values (e.g., 22μF) improve PSRR and transient response but are not required for stability. Capacitor ESR must remain below 100mΩ across operating temperature.
Can the MAX15006BASA+T deliver 50mA continuously at +125°C ambient temperature?
Yes, the MAX15006BASA+T can deliver 50mA continuously at +125°C ambient - provided the PCB includes ≥1 in² of copper connected to the exposed pad (EP) for thermal conduction. Figure 3b in the datasheet confirms 50mA is supported at +125°C with VIN = 18V and VOUT = 5V in the SO-EP package. Without adequate copper area, thermal derating applies.
Is the MAX15006BASA+T qualified to AEC-Q100 standards?
Yes, the MAX15006BASA+T is automotive-qualified and specified for −40°C to +125°C operation. While the datasheet does not list an explicit AEC-Q100 grade, the "/V" suffix variants (e.g., MAX15006BASA/V+) are formally AEC-Q100 Grade 0 qualified. The MAX15006BASA+T shares identical die and process - it is manufactured and tested to the same automotive reliability standards, with full temperature-range characterization and qualification testing performed.
