Analog Devices Inc./Maxim Integrated MAX15006BATT/V+

Overview

MAX15006BATT/V+ from Maxim Integrated is an automotive-grade, ultra-low quiescent-current linear regulator with fixed 5V output, 4V–40V input range, 50mA guaranteed output current, 300mV dropout at 50mA, and operation over –40°C to +125°C. It delivers stable power in battery-supplied automotive subsystems such as tire-pressure monitoring sensors where low standby consumption and cold-crank resilience are critical.

For engineers reviewing the MAX15006BATT/V+ datasheet, MAX15006BATT/V+ pinout, MAX15006BATT/V+ application, or MAX15006BATT/V+ equivalent, key selection factors include its 10μA no-load ground current, TDFN-6EP thermally enhanced package, 45V load-dump tolerance, and compatibility with 2.2μF ceramic output capacitors for space-constrained designs.

Technical Context

The MAX15006BATT/V+ uses a p-channel pass transistor architecture enabling ultra-low quiescent current across full load (90μA at 50mA) and wide input voltage range (4V–40V). Its internal 1.23V reference and error amplifier regulate output with ±1.5% load regulation and 0.25% line regulation - critical for maintaining accuracy during automotive battery transients.

Unlike the MAX15007 series, this variant lacks an enable (EN) input and fixed FB pin; it is a non-adjustable, always-on regulator. Thermal shutdown activates at +165°C with 20°C hysteresis, and short-circuit protection sustains indefinite GND shorts without damage.

Key Specifications

Pinout & Package

MAX15006BATT/V+ is housed in a thermally enhanced 6-pin TDFN-EP (3mm × 3mm) package with exposed pad connected internally to GND. The exposed pad must be soldered to PCB ground plane for optimal thermal performance and is not intended as a functional ground connection.

FAQ

What is the maximum input voltage the MAX15006BATT/V+ can withstand during load dump?

The MAX15006BATT/V+ is rated for absolute maximum IN-to-GND voltage of +45V. While continuous operation is specified up to 40V, it survives ISO 7637-2 Pulse 5a load-dump transients (up to 45V for 400ms) without damage or latch-up - eliminating need for external TVS diodes in most automotive implementations. This rating is validated across the full –40°C to +125°C temperature range.

Does the MAX15006BATT/V+ include an enable (EN) pin?

No, the MAX15006BATT/V+ does not include an enable input. It is a permanently enabled, fixed-output variant of the MAX15006 family. The enable function is exclusive to the MAX15007 series (e.g., MAX15007BATT/V+). For on/off control of MAX15006BATT/V+, external MOSFET switching on the IN rail is required.

What output capacitor value is required for stable operation of the MAX15006BATT/V+?

The MAX15006BATT/V+ requires a minimum 2.2μF low-ESR ceramic output capacitor for guaranteed stability 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 basic regulation. Capacitor ESR must remain below 100mΩ.

Is the MAX15006BATT/V+ pin-compatible with other MAX15006 variants?

Yes, all MAX15006xATT+ and MAX15006xATT/V+ variants share identical 6-pin TDFN-EP pinout and footprint. However, pin functions differ: MAX15006C variants expose FB on Pin 5 instead of OUT, and MAX15007 variants replace Pin 3 (N.C.) with EN. Always verify schematic symbol and netlist against the specific variant's pin description table.

What is the thermal performance difference between MAX15006BATT/V+ and MAX15006BASA/V+?

The MAX15006BATT/V+ in TDFN-6EP has θJA = 42°C/W, while the MAX15006BASA/V+ in SO-EP has θJA = 53°C/W. At +70°C ambient, the TDFN package dissipates 1.904W vs. 1.509W for SO-EP - a 26% higher power handling capability. This enables higher output current or operation in hotter environments without derating.
