Product details
Overview
MAX6770TALD2+T from Maxim Integrated is an automotive-grade micropower linear regulator with integrated supervisor, delivering 5.0V fixed output at up to 100mA from 4V–72V input. It features active-low open-drain RESET with 12.5ms fixed timeout (D2 suffix), 31µA quiescent current, and -40°C to +125°C operation - designed for always-on vehicle modules including body control units and infotainment power rails.
For engineers reviewing the MAX6770TALD2+T datasheet, MAX6770TALD2+T pinout, MAX6770TALD2+T application, or MAX6770TALD2+T equivalent, key selection criteria include its AEC-Q100-qualified 3mm × 3mm TDFN-6 package, 620mV dropout at 100mA/5V, adjustable reset threshold via external divider, and single ENABLE input architecture - critical for low-power ignition-synchronized systems.
Technical Context
The MAX6770TALD2+T implements a high-voltage linear regulation architecture with internal 1.233V reference and precision bandgap-controlled error amplifier. Its supervisor block monitors OUT voltage against a factory-trimmed 4.625V reset threshold (L suffix) and asserts RESET for ≥12.5ms (D2) after recovery, using an internal ramp generator tied to TIMEOUT pin.
This variant belongs to the MAX6765–MAX6774B family's single-enable subgroup (MAX6765/MAX6766/MAX6769/MAX6770/MAX6773/MAX6773B/MAX6774/MAX6774B), omitting HOLD, WDI, RESETIN, ENABLE1/ENABLE2, and dual-mode SET functionality - confirming it as a fixed-output, fixed-threshold, fixed-timeout supervisor regulator without watchdog or adjustable-VOUT capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 72V - supports full automotive battery range including cold-crank (4.5V) and load-dump (65V) transients. |
| Output Voltage | 5.0V ±1.5% (4.925V–5.075V) - factory-trimmed for stable MCU core/logic rail without external feedback. |
| Quiescent Current | 31µA typical at no load - enables <100µA system standby power in always-on modules. |
| Dropout Voltage | 620mV at 100mA - ensures regulation down to VIN = 5.62V, critical for start-stop operation. |
| RESET Threshold | 4.625V (L option) - asserts RESET when 5V rail drops below 92.5% nominal, preventing brownout execution. |
| Reset Timeout | 12.5ms (D2 option) - guarantees µP reset pulse width exceeds minimum requirement of most automotive MCUs. |
| Operating Temp | -40°C to +125°C - fully specified across extended automotive temperature range. |
| Package | 6-pin TDFN-EP (3mm × 3mm) - thermally enhanced for 1.9W dissipation; exposed pad must be soldered to PCB ground plane. |
Pinout & Package
MAX6770TALD2+T uses a 6-pin thermally enhanced TDFN-EP package (outline 21-0137, land pattern 90-0058) with exposed pad (EP) internally connected to GND. The EP must be soldered to a dedicated PCB ground plane for thermal management and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator Input | Bypass with ≥0.1µF ceramic capacitor to GND; withstands 80V absolute max; supplies all internal circuitry. |
| 2 GND | Ground Reference | Primary return path for regulator output, RESET sink, and internal logic; connects to EP for thermal conduction. |
| 3 ENABLE | Active-High Enable Input | Drives regulator ON when pulled >1.4V; internally pulldown-biased (0.6µA); controls startup sequencing. |
| 4 RESET | Active-Low Open-Drain Output | Sinks ≥3.2mA at 0.4V; requires external pullup; asserts during undervoltage and remains low for 12.5ms post-recovery. |
| 5 TIMEOUT | Reset Timeout Adjust Input | Internally connected to OUT for fixed 12.5ms timeout (D2); leave unconnected if not used for adjustable timing. |
| 6 OUT | Regulated Output | Delivers 5.0V @ ≤100mA; bypass with ≥10µF ceramic capacitor; protected by overtemperature and short-circuit shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Qualified per AEC-Q100 Rev H for automotive applications - validated for reliability under temperature cycling, humidity, and vibration stress. |
| Low Dropout Design | 620mV dropout at 100mA enables stable 5V output even during 6V battery cranking events. |
| Integrated Supervisor | Monitors own output voltage and asserts RESET with guaranteed 12.5ms pulse width - eliminates need for discrete reset IC. |
| Thermal Protection | Shuts down at +160°C junction temp with +20°C hysteresis - prevents damage during sustained overload or high ambient conditions. |
| High-Voltage Robustness | Withstands 80V absolute max on IN and 12V on RESET/ENABLE - survives ISO 7637-2 pulse 5a (load dump) without external clamping. |
| Small Thermally Optimized Package | 3mm × 3mm TDFN-6 with exposed pad achieves 42°C/W θJA (multi-layer board) - supports continuous 100mA operation at +85°C ambient. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator with supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6765TTLD2+T | Same 5V/4.625V/D2 configuration but lacks AEC-Q100 qualification; 31µA IQ, identical pinout and specs except automotive stress testing. | Approved for industrial or non-automotive embedded systems only; not accepted in Tier 1 automotive BOMs. | Select MAX6765TTLD2+T only for cost-sensitive non-automotive designs where AEC-Q100 is not required. |
| TLV70750PDQNR | Lower voltage range (2.5V–5.5V), higher IQ (25µA), no integrated RESET, SOT-23-5 package; lacks high-voltage tolerance and supervisor. | Only suitable for post-regulation 5V rails downstream of primary DC-DC converter; cannot replace directly in battery-connected applications. | Use TLV70750PDQNR only in secondary 5V domains where input is already regulated and reset is handled externally. |
Compared with MAX6765TTLD2+T, MAX6770TALD2+T adds AEC-Q100 qualification for automotive deployment; compared with TLV70750PDQNR, it provides full 4V–72V direct-battery operation, integrated RESET, and thermal protection - making it the only drop-in solution for primary automotive 5V rail generation.

FAQ
What is the exact reset threshold voltage for MAX6770TALD2+T?
The MAX6770TALD2+T has a factory-trimmed reset threshold of 4.625V (L suffix), meaning RESET asserts when the regulated 5.0V output falls below this value and remains asserted for the full 12.5ms timeout period after recovery. This threshold is guaranteed across -40°C to +125°C and matches the L option in Table 2 of the datasheet.
Does MAX6770TALD2+T support adjustable output voltage?
No, MAX6770TALD2+T does not support adjustable output voltage. It is a fixed 5.0V output device (T suffix indicates 3.3V; L suffix here denotes reset threshold, not output). Adjustable VOUT requires SET pin functionality found only in MAX6767–MAX6774B variants - MAX6770TALD2+T lacks the SET pin and internal feedback divider for adjustment.
Can MAX6770TALD2+T be used without connecting the TIMEOUT pin?
Yes, MAX6770TALD2+T can be used with TIMEOUT left unconnected because the D2 suffix indicates an internally fixed 12.5ms reset timeout. TIMEOUT is internally tied to OUT in this configuration, so no external capacitor or connection is required - simplifying layout and reducing BOM count for standard reset timing.
Is the exposed pad (EP) on MAX6770TALD2+T electrically connected?
Yes, the exposed pad (EP) on MAX6770TALD2+T is internally connected to GND and must be soldered to a PCB ground plane. It serves both thermal conduction (reducing θJA to 42°C/W) and electrical grounding - floating or isolated EP compromises thermal performance and may cause instability or premature thermal shutdown.
What is the maximum continuous output current for MAX6770TALD2+T at 85°C ambient?
At +85°C ambient and VIN = 14V, MAX6770TALD2+T delivers up to 100mA continuously when using a 4-layer PCB with proper EP grounding. Derating applies above +70°C (23.8mW/°C), limiting power dissipation to ~1.4W at +85°C - sufficient for 100mA at 5V output with 9V input, but reduced at higher VIN or elevated ambient.
