Product details
Overview
TLE72702EXUMA1 from Infineon Technologies is a monolithic 5-V low-dropout voltage regulator with ±2% output accuracy, 300 mA output current capability, and ultra-low 20 µA quiescent current. It integrates power-on/undervoltage reset, overtemperature shutdown, and output current limiting, and is AEC-Q100 qualified for automotive microcontroller supply in engine control units and body electronics.
For engineers reviewing the TLE72702EXUMA1 datasheet, TLE72702EXUMA1 pinout, TLE72702EXUMA1 application, or TLE72702EXUMA1 equivalent, key selection criteria include dropout voltage ≤500 mV at 200 mA, reset output compatibility with open-collector logic, ceramic capacitor support down to 470 nF, and thermal resistance of 47 K/W (PG-SSOP-14 exposed pad) under natural convection.
Technical Context
The TLE72702EXUMA1 employs a charge pump-based internal reference and integrated reset generator with selectable delay timing via DT pin connection to GND or Q. Its regulation loop maintains stable 5 V output across input voltages from 5.5 V to 42 V and junction temperatures from –40 °C to 150 °C.
Protection architecture includes foldback current limiting (301 mA trip, up to 800 mA short-circuit current), thermal shutdown activation at Tj ≥ 150 °C, and reverse-current sink circuitry limiting Q-pin voltage to ≤5.5 V - enabling safe operation in battery-connected always-on systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2% (4.9–5.1 V); meets MCU core supply tolerance requirements without external trimming |
| Max Output Current | 300 mA continuous; supports typical automotive microcontrollers and CAN transceivers |
| Dropout Voltage | 250–500 mV at 200 mA; enables regulation from 5.5 V input, critical for cold-crank scenarios |

| ESD Rating | HBM ±3 kV, CDM ±1.5 kV; qualified for automotive assembly and field environments |
Pinout & Package
Package: PG-SSOP-14 exposed pad (RoHS-compliant, AEC-Q100 qualified). Exposed pad must be soldered to PCB ground plane for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,3,5,7 | n.c. | Non-connected; may be left floating or tied to GND for mechanical stability |
| 2 | RO | Open-collector reset output with internal pull-up; drives MCU /RESET pin directly |
| 4 | GND | Main ground reference and thermal path for exposed pad |
| 6 | DT | Selects power-on reset delay time by connecting to GND (short delay) or Q (long delay) |
| 8,10,11,12,14 | n.c. | Non-connected; no internal connection; optional GND tie for EMI reduction |
| 9 | Q | Regulated 5 V output; requires ≥470 nF ceramic capacitor with ESR ≤10 Ω at 10 kHz |
| 13 | I | Input (42 V max); must be decoupled with ceramic capacitor directly at pin |
| Pad | Exposed Pad | Internally connected to GND; primary thermal path to PCB heatsink area |
Key Features

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, 25 µA Iq, 300 mV dropout, but not AEC-Q100 qualified; SOT-23-5 package | Limited to industrial or non-safety-critical automotive infotainment; lacks reset output and thermal shutdown | Select only for cost-sensitive, non-automotive designs where AEC qualification and integrated protection are unnecessary |
| TPS7B6950QDCYRQ1 | 300 mA, 35 µA Iq, 450 mV dropout, AEC-Q100 Grade 1, integrated reset with fixed delay | Supports only –40 °C to +125 °C; lacks DT pin configurability and reverse-current sink | Prefer when Grade 1 temperature range suffices and fixed-reset timing simplifies layout |
Compared with TLV73350PDBVR and TPS7B6950QDCYRQ1, the TLE72702EXUMA1 uniquely combines Grade 0 temperature rating, programmable reset delay, reverse-current protection, and 47 K/W thermal resistance in SSOP-14 - making it optimal for high-reliability engine bay applications requiring full AEC compliance and robust fault handling.

FAQ
What is the minimum input voltage required for regulation?
The TLE72702EXUMA1 requires a minimum input voltage of 5.5 V to maintain regulated 5 V output. Below this threshold, the device enters undervoltage lockout and asserts the RO pin low. This ensures clean reset behavior during battery recovery after cranking events.
Can the reset delay be adjusted externally?
Yes - the DT pin selects between two factory-set power-on reset delays: connect DT to GND for short delay (~10 ms), or to Q for long delay (~100 ms). No external RC network is needed, and both options are fully characterized across temperature and voltage.
Is an external pull-up resistor required on the RO pin?
No - the RO pin has an integrated pull-up resistor. An external resistor ≥10 kΩ to Q is optional only if higher noise immunity or faster rise time is needed. Leaving RO unconnected is acceptable if reset functionality is unused.
Why does the datasheet specify 470 nF minimum output capacitance?
The 470 nF minimum ensures loop stability across all operating conditions, including worst-case ±30% capacitor tolerance and ESR ≤10 Ω at 10 kHz. Lower values risk oscillation due to the regulator's charge-pump reference architecture and internal compensation.
