Product details
Overview
TLE72762DATMA1 from Infineon Technologies is a monolithic 5-V low-dropout linear voltage regulator designed for automotive power supply rails, delivering up to 300 mA output current with ±2% output voltage accuracy (4.9 V to 5.1 V), ultra-low quiescent current (20 µA typ.), and integrated enable control. It operates from 5.5 V to 42 V input, features overtemperature shutdown, output current limiting, and supports ceramic output capacitors as low as 470 nF.
For engineers reviewing the TLE72762DATMA1 datasheet, TLE72762DATMA1 pinout, TLE72762DATMA1 application, or TLE72762DATMA1 equivalent, key selection criteria include dropout voltage ≤500 mV at 200 mA, AEC-Q100 qualification, junction temperature range of −40 °C to +150 °C, exposed-pad thermal performance, and EN-controlled ultra-low standby current (5 µA typ.).
Technical Context
The TLE72762DATMA1 employs a charge-pump-assisted bandgap reference architecture to maintain regulation under ultra-low quiescent current constraints, enabling permanent battery connection in automotive always-on systems. Its internal protection includes foldback current limiting (301 mA trip, 800 mA short-circuit limit) and thermal shutdown triggered above 150 °C junction temperature.
Stability is achieved with minimal external capacitance (≥470 nF, ESR ≤10 Ω at 10 kHz), eliminating need for electrolytic or tantalum capacitors. The device's reverse-current sink circuit clamps output voltage to <5.5 V during reverse-bias conditions, protecting downstream loads without external diodes.

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 output, 65 µA IQ, SOT-23-5 package, no AEC-Q100 qualification | Lacks automotive qualification and thermal robustness; limited to cabin-grade consumer or industrial use | Select only for non-automotive designs where qualification and 150 °C operation are not required |
| TPS7B6750QDCYRQ1 | 300 mA, 5-V output, 30 µA IQ, SOIC-8 package, AEC-Q100 Grade 1 (−40 °C to +125 °C) | Lower max junction temperature (125 °C vs. 150 °C); higher quiescent current than TLE72762DATMA1 | Prefer when SOIC-8 footprint is mandated and under-hood ambient stays below 125 °C |
Compared with TLV73350PDBVR and TPS7B6750QDCYRQ1, the TLE72762DATMA1 uniquely combines AEC-Q100 Grade 0 qualification, 150 °C operation, and 20 µA quiescent current-making it the only choice for high-reliability, high-temperature automotive power nodes requiring zero parasitic drain.

FAQ
What is the minimum output capacitance required for stable operation?
The TLE72762DATMA1 requires a minimum 470 nF ceramic output capacitor with ESR ≤10 Ω at 10 kHz. This value accounts for worst-case ±30% capacitance tolerance and ensures phase margin and transient response meet automotive specification limits across temperature and load conditions.
Does the device support reverse-voltage protection on the output pin?
Yes-the TLE72762DATMA1 integrates an output sink circuit that actively clamps the Q pin voltage to <5.5 V during reverse-current events (e.g., battery disconnection or backfeed), eliminating need for external blocking diodes in most automotive configurations.
Can the EN pin be left floating?
No-EN has an internal pull-down resistor but must be actively driven high (≥2.0 V) to enable regulation. Leaving it unconnected risks intermittent enable/disable behavior due to noise coupling; best practice is to tie to VI or microcontroller GPIO with defined logic levels.
Is the exposed pad electrically connected internally?
Yes-the exposed pad is internally bonded to GND and serves as the primary thermal and electrical return path. It must be soldered to a PCB copper pour connected to system ground; omitting this connection causes thermal runaway and premature failure under load.
