Product details
Overview
TLE72702GATMA1 from Infineon Technologies is a monolithic 5-V low-dropout linear voltage regulator with integrated power-on/undervoltage reset, rated for 300 mA output current, ±2% output voltage accuracy (4.9–5.1 V), and ultra-low quiescent current of 20 µA typical. It operates across input voltages from 5.5 V to 42 V and supports automotive ECU supply with junction temperature range from −40 °C to +150 °C.
For engineers reviewing the TLE72702GATMA1 datasheet, TLE72702GATMA1 pinout, TLE72702GATMA1 application, or TLE72702GATMA1 equivalent, key selection criteria include its reset timing configurability via DT pin, ceramic capacitor compatibility down to 470 nF, overtemperature shutdown, output current limiting (301 mA trip), and PG-TO263-5 exposed-pad thermal performance.
Technical Context
The TLE72702GATMA1 integrates a charge pump-based LDO core with bandgap reference and internal reset generator featuring selectable power-on delay via DT pin connection (to GND or Q). Its architecture enables stable regulation under wide input transients while maintaining <250 mV dropout at 200 mA load.
Reset functionality asserts low on RO (open-collector) when VQ falls below threshold or during power-up; the IC sustains valid reset assertion down to VQ = 1 V and includes integrated sink current to clamp Q voltage ≤5.5 V during reverse-current events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2% (4.9–5.1 V); ensures MCU I/O and logic compatibility across automotive temperature and line/load variations. |
| Max Output Current | 300 mA continuous; supports mid-power ECUs like body control modules without external pass devices. |
| Dropout Voltage | 250 mV typ. at 200 mA; enables operation with VI as low as 5.25 V while sustaining regulated 5 V output. |
| Quiescent Current | 20 µA typ.; allows permanent VBAT connection in always-on automotive domains (e.g., alarm, CAN wake-up). |
| Operating Temp | −40 °C to +150 °C junction; qualified per AEC-Q100 Grade 0 for under-hood applications. |
| Reset Threshold | Valid reset asserted down to VQ = 1 V; guarantees reliable microcontroller reset during brown-out and battery recovery. |
| Output Cap Min | 470 nF ceramic; enables compact, high-reliability filtering without tantalum or electrolytic capacitors. |
Pinout & Package
Package: PG-TO263-5 (D²PAK) with exposed thermal pad internally connected to GND; requires PCB copper area ≥600 mm² for RthJA = 38 K/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 I | Input voltage supply | Accepts 5.5–42 V; must be decoupled with ceramic capacitor directly at pin. |
| 2 RO | Open-collector reset output | Pulled low during power-up or undervoltage; internal pull-up enables direct MCU reset input interface. |
| 3 GND | Ground reference & thermal path | Internally bonded to heat slug; must connect to large PCB ground plane for thermal management. |
| 4 DT | Delay timing select | Connect to GND or Q to set POR delay time; configures reset assertion duration during startup. |
| 5 Q | Regulated 5 V output | Delivers up to 300 mA; requires local 470 nF ceramic cap with ESR ≤10 Ω @ 10 kHz. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power-On Reset | Configurable delay via DT pin; eliminates need for external RC reset circuitry in ECU designs. |
| Reverse-Current Sink Protection | Clamps Q pin ≤5.5 V during reverse current flow; prevents overvoltage damage to downstream 5 V logic. |
| Overtemperature Shutdown | Thermal protection activates at Tj ≥150 °C; latches off until cooldown, preventing thermal runaway. |
| AEC-Q100 Qualified | Grade 0 (−40 °C to +150 °C); validated for safety-critical automotive power rails including engine control units. |
| Ceramic Capacitor Stability | Stable with 470 nF X7R/X5R ceramics; reduces BOM count and improves long-term reliability vs. electrolytics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 5 V automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | 300 mA, 5 V, 60 µA IQ, SOT-23-5; no integrated reset, lower temp rating (−40 °C to +125 °C) | Lacks POR/UVLO; unsuitable for AEC-Q100 Grade 0 or under-hood use | Select only for non-automotive, cost-sensitive, space-constrained designs where reset is handled externally. |
| TPS7B6950QDCYRQ1 | 300 mA, 5 V, 30 µA IQ, SOT-223-4; integrated reset, AEC-Q100 Grade 1 (−40 °C to +125 °C) | Lower max junction temperature; lacks reverse-current sink and DT-configurable delay | Prefer for cabin-grade ECUs where 125 °C suffices and simplified reset timing is acceptable. |
Compared with TLV73350PDBVR and TPS7B6950QDCYRQ1, the TLE72702GATMA1 uniquely combines Grade 0 temperature rating, DT-selectable reset timing, reverse-current sink protection, and 20 µA quiescent current-making it the only choice for high-reliability, under-hood 5 V regulation with integrated system-level reset control.

FAQ
What is the minimum output capacitance required for stable operation?
The TLE72702GATMA1 requires a minimum 470 nF ceramic capacitor at the Q pin, with ESR ≤10 Ω at 10 kHz. This value accounts for worst-case ±30% capacitance tolerance and ensures phase margin stability across temperature and load. Larger values improve ripple rejection but do not affect basic regulation stability.
How does the DT pin affect reset timing?
Connecting DT to GND selects a shorter power-on reset delay (~10 ms), while connecting DT to Q extends the delay to ~100 ms. This dual-mode timing allows synchronization with other system components or accommodates slower-rising input rails. The DT pin has no function if left floating or unconnected.
Can the TLE72702GATMA1 be used with input voltages below 6 V?
No-the functional input voltage range starts at 5.5 V, and regulation is not guaranteed below that. At VI = 5.5 V, the 250 mV typical dropout means VQ may drop to 5.25 V, outside the ±2% spec. For sub-6 V inputs, a different regulator architecture (e.g., buck-boost) is required.
Is an external pull-up resistor needed on the RO pin?
An external pull-up resistor ≥10 kΩ to Q is optional and only recommended if the MCU reset input has weak internal pull-up or requires faster rise time. The RO pin includes an internal pull-up; leaving it open is acceptable when interfacing with standard automotive MCUs that specify open-collector reset compatibility.
