Product details
Overview
TLE72782GV50XUMA1 from Infineon Technologies is a dual-channel linear voltage regulator IC delivering fixed 5 V output per channel with 180 mA current capability, integrated thermal shutdown and overcurrent protection, and designed for automotive body electronics power management in 12 V battery systems.
For engineers reviewing the TLE72782GV50XUMA1 datasheet, TLE72782GV50XUMA1 pinout, TLE72782GV50XUMA1 application, or TLE72782GV50XUMA1 equivalent, key selection criteria include dual independent 5 V regulation, automotive-grade AEC-Q100 qualification, DSO-14 package thermal performance, and enable/control logic compatibility with microcontroller I/Os.
Technical Context
This device integrates two independent low-dropout (LDO) regulators on a single die, each featuring internal current limiting, thermal foldback, and reverse-battery protection. It operates across input voltages from 4.5 V to 40 V and supports load dump transients up to 45 V per ISO 7637-2 Pulse 5a.
The IC uses a dedicated EN1/EN2 control interface for per-channel activation and includes open-drain fault flag outputs (FLT1/FLT2) indicating overtemperature or short-circuit conditions. No external compensation components are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% per channel - ensures stable MCU and sensor supply under battery variation. |
| Max Output Current | 180 mA per channel - sufficient for powering multiple automotive ECUs' logic rails. |
| Input Voltage Range | 4.5 V to 40 V - supports cold-crank (4.5 V) and load-dump (40 V) conditions in 12 V systems. |
| Dropout Voltage | Typ. 220 mV at 180 mA - enables regulation down to 5.22 V input, critical during cranking. |
| Quiescent Current | Typ. 120 µA per channel in standby - minimizes battery drain in always-on modules. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - qualified for under-hood automotive applications. |
Pinout & Package
Supplied in a thermally enhanced DSO-14 (14-pin double-sided鸥翼) package with exposed thermal pad (EP), enabling PCB-level heat dissipation up to 1.5 W at 40 °C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN1 | Channel 1 input | Accepts 4.5–40 V supply; connects to main 12 V rail with local decoupling. |
| VOUT1 | Channel 1 output | Delivers regulated 5 V to connected loads; requires 10 µF ceramic output capacitor. |
| EN1 | Channel 1 enable | Active-high logic input; pulls high via internal 100 kΩ resistor when unconnected. |
| FLT1 | Channel 1 fault flag | Open-drain output pulled low during overtemperature or overload; requires external pull-up. |
| GND | Power ground | Common reference for both channels and thermal pad connection point. |
| VIN2 | Channel 2 input | Independent input for second 12 V domain or redundancy path. |
| VOUT2 | Channel 2 output | Second isolated 5 V rail; electrically separated from VOUT1 for fault containment. |
| EN2 | Channel 2 enable | Independent control allows staggered startup or functional partitioning. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs | Enables separate power domains for safety-critical and non-critical subsystems without cross-fault propagation. |
| Integrated reverse-battery protection | Eliminates need for external series diode, reducing BOM count and forward voltage drop. |
| Load dump robustness (45 V) | Withstands ISO 7637-2 Pulse 5a without external TVS, simplifying front-end design. |
| Thermal shutdown with hysteresis | Shuts down at 165 °C and re-enables at 145 °C, preventing thermal cycling damage during sustained overload. |
Applications
| Body Control Module (BCM) | Door Control Unit (DCU) |
|---|---|
Use Scenario: Powering microcontroller, CAN transceiver, and window motor driver logic in centralized vehicle body electronics. IC Role / Device Role / Timing Role: Dual 5 V LDO supplying isolated rails for MCU core and peripheral I/O domains. Use Value: Independent EN/FLT pins allow firmware-controlled power sequencing and fault isolation per subsystem. | Use Scenario: Providing regulated 5 V to mirror adjustment ICs, lock actuators, and proximity sensors in door modules. IC Role / Device Role / Timing Role: Primary 5 V regulator with reverse-battery and load-dump immunity for harsh door environment. Use Value: Integrated protection reduces external component count by ≥3 parts versus discrete solutions. |
| Seat Control Module | Lighting Control Unit (LCU) |
Use Scenario: Supplying memory seat controller MCU and position sensor interface circuitry. IC Role / Device Role / Timing Role: Dual-rail regulator supporting separate 5 V supplies for analog sensor front-end and digital logic.

IC Role / Device Role / Timing Role: Stable 5 V source for precision analog sensing and digital communication interfaces. Use Value: Low quiescent current (<120 µA/channel) extends battery life in parked vehicle mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70733PDPWR | Single-channel, 3.3 V fixed output, max 200 mA, no fault flags or AEC-Q100 rating. | Limited to non-automotive, single-rail applications requiring lower voltage. | Select only for cost-sensitive industrial designs without fault reporting or dual-rail needs. |
| TPS7B8150QDGNRQ1 | Single-channel, 5 V, 500 mA, AEC-Q100 Grade 1, but lacks dual output and FLT/EN per channel. | Suitable for higher-current single-rail automotive use, but cannot replace dual-domain architecture. | Choose when one high-current 5 V rail suffices and board space permits two separate ICs. |
Compared with TLV70733PDPWR and TPS7B8150QDGNRQ1, the TLE72782GV50XUMA1 uniquely delivers dual independent AEC-Q100-compliant 5 V rails with per-channel control and fault signaling-enabling functional safety partitioning not achievable with single-channel alternatives.

FAQ
What is the maximum junction temperature for continuous operation?
The TLE72782GV50XUMA1 has a maximum junction temperature of +150 °C. Thermal shutdown activates at +165 °C with 20 °C hysteresis, and continuous operation at rated load is guaranteed up to +125 °C ambient when mounted on a 4-layer PCB with 2 cm² copper pour under the EP pad.
Does this IC require external capacitors for stability?
Yes: each output requires a minimum 10 µF ceramic capacitor (X5R/X7R, ≤10 mΩ ESR) placed within 5 mm of VOUT and GND pins. Input capacitance of ≥10 µF is also recommended at VIN1/VIN2 to suppress transients and ensure stability during load dump events.
Can EN1 and EN2 be tied together for simultaneous enable?
Yes - EN1 and EN2 may be connected to a common microcontroller GPIO or system enable signal. However, doing so forfeits independent channel control and fault isolation; the datasheet confirms functional compatibility but notes that individual fault flag monitoring becomes impossible in this configuration.
Is the thermal pad electrically connected to GND?
Yes: the exposed thermal pad (EP) is internally connected to GND and must be soldered to a solid GND plane on the PCB. This connection is mandatory for thermal performance and electrical safety; floating or insulated mounting degrades thermal resistance by >40% and violates Infineon's layout guidelines.
