Product details
Overview
MAX15006CATT+T from Maxim Integrated is an ultra-low quiescent-current adjustable linear regulator designed for automotive and battery-powered systems. It operates from 4V to 40V input, delivers up to 50mA output current, consumes only 8–15µA no-load ground current, features 1.23V feedback reference, and supports 1.8V–10V adjustable output via external resistor divider. It is used in tire-pressure monitoring sensors where cold-crank operation and load-dump tolerance are critical.
For engineers reviewing the MAX15006CATT+T datasheet, MAX15006CATT+T pinout, MAX15006CATT+T application, or MAX15006CATT+T equivalent, key selection criteria include its 300mV dropout at 50mA (for VOUT ≥ 3.3V), thermal shutdown at +165°C with 20°C hysteresis, stable operation with 2.2µF ceramic output capacitor, -40°C to +125°C automotive temperature range, and TDFN-EP package compatibility with high-power-density PCB layouts.
Technical Context
The MAX15006CATT+T implements a p-channel pass transistor architecture enabling ultra-low quiescent current across full load (90µA at 50mA) and wide input range (4V–40V). Its internal 1.23V bandgap reference feeds an error amplifier that regulates output voltage via external FB resistive divider - no internal voltage-setting resistors are present.
Unlike fixed-output variants, the MAX15006CATT+T lacks enable logic and EN pin; it is always-on. Protection includes short-circuit current limiting (175mA typ), thermal shutdown with automatic recovery, and absolute maximum ratings covering 45V load dump and -0.3V to +45V IN-to-GND stress.
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 Voltage Range | 1.8V to 10V adjustable - set by external R1/R2 divider; requires ≥5µA divider current for stability. |
| Max Output Current | 50mA guaranteed - limited by thermal design; actual available current depends on VIN, VOUT, ambient temperature, and PCB copper area. |
| Quiescent Ground Current | 8–15µA at no load (TA = -40°C to +125°C) - enables multi-year battery life in low-duty-cycle sensor nodes. |
| Dropout Voltage | 300mV at 50mA (typ) - ensures regulation down to VIN = VOUT + 0.3V, critical for low-input-voltage operation. |
| Feedback Reference Voltage | 1.23V ±30mV - defines output accuracy; VOUT = 1.23 × (1 + R1/R2), enabling precise programmable rail generation. |
| Thermal Shutdown Threshold | +165°C junction temperature with 20°C hysteresis - provides robust fault protection without latch-up during sustained overload. |
Pinout & Package
MAX15006CATT+T is housed in a thermally enhanced 6-pin TDFN-EP (3mm × 3mm) package with exposed pad connected internally to GND. The EP must be soldered to PCB ground plane for optimal thermal performance (θJA = 42°C/W).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | IN | Regulator input supply (4V–40V); bypass with 0.1µF ceramic capacitor to GND near pin. |
| 3 | N.C. | No internal connection; leave unconnected - not usable as signal or ground path. |
| 4 | GND | Analog and power ground reference; connects to EP for thermal conduction. |
| 5, 6 | OUT | Regulated output; requires ≥2.2µF low-ESR ceramic capacitor to GND for stability across -40°C to +125°C. |
| - | FB | Feedback node - connect external resistor divider (OUT → FB → GND) to set output voltage; 1.23V reference target. |
| EP | Exposed Pad | Internally tied to GND; mandatory solder connection to PCB ground plane for thermal dissipation (not functional ground path). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 8–15µA no-load ground current over full automotive temperature range (-40°C to +125°C), enabling >10-year battery life in TPMS. |
| Adjustable output (1.8V–10V) | Configurable via two-resistor divider; 1.23V FB reference ensures ±2.4% output accuracy over temp and line/load conditions. |
| Stable with minimal output capacitance | Guaranteed stability with only 2.2µF ceramic output capacitor - reduces BOM cost and board space vs. traditional LDOs requiring ≥10µF. |
| High-voltage transient tolerance | Withstands 45V load dump and operates through cold-crank (down to 4V input) - eliminates need for upstream TVS or pre-regulator in automotive ECUs. |
| Integrated protection | Short-circuit current limit (175mA), thermal shutdown (+165°C), and safe operating area control prevent damage during fault conditions. |
Applications
| Tire-Pressure Monitoring Sensor (TPMS) | Automotive Body Control Module (BCM) |

FAQ
What is the minimum output capacitor required for stable operation of MAX15006CATT+T?
The MAX15006CATT+T requires a minimum 2.2µF low-ESR ceramic output capacitor for guaranteed stability across -40°C to +125°C. Larger values (e.g., 22µF) improve load-transient response and PSRR but are not required for basic regulation. X7R dielectric is recommended to maintain ≥1.3µF minimum capacitance over temperature.
Does MAX15006CATT+T include an enable (EN) pin?
No, MAX15006CATT+T does not include an enable pin. It is an always-on regulator. The EN pin is exclusive to the MAX15007 series (e.g., MAX15007CATT+T). For enable functionality with adjustable output, MAX15007CATT+T is the direct functional counterpart.
What is the feedback reference voltage of MAX15006CATT+T and how is output voltage calculated?
The MAX15006CATT+T has a 1.23V ±30mV feedback reference voltage (VFB). Output voltage is calculated as VOUT = VFB × (1 + R1/R2), where R1 connects OUT to FB and R2 connects FB to GND. A minimum 5µA current through the divider is required for stability.
Can MAX15006CATT+T withstand automotive load dump events?
Yes, MAX15006CATT+T is rated for 45V absolute maximum input voltage and is designed to survive standard automotive load dump transients (ISO 7637-2 Pulse 5a). Its 40V operating input range and internal protection circuitry eliminate the need for external TVS diodes in most implementations.
What package type and thermal characteristics apply to MAX15006CATT+T?
MAX15006CATT+T uses a 6-pin TDFN-EP package (3mm × 3mm) with exposed pad. Its thermal resistance is θJA = 42°C/W (JEDEC 4-layer board) and θJC = 9°C/W. The EP must be soldered to PCB ground plane to achieve rated power dissipation (1.904W at TA = +70°C, derating 23.8mW/°C above).
