Product details
Overview
TLE42702GATMA1 from Infineon Technologies is a 5 V fixed-output, low-dropout linear voltage regulator with integrated reset functionality, ±2% output voltage tolerance, 650 mA continuous output current capability, and automotive-grade AEC-Q100 qualification. It operates over 6–42 V input range, features reverse polarity protection, overvoltage protection up to 65 V (≤400 ms), and thermal shutdown-designed for engine control units and body electronics power rails.
For engineers reviewing the TLE42702GATMA1 datasheet, TLE42702GATMA1 pinout, TLE42702GATMA1 application, or TLE42702GATMA1 equivalent, key selection criteria include its adjustable reset delay via external capacitor, 350 mV typical dropout at 550 mA, integrated 30 kΩ internal pull-up on reset output, and PG-TO263-5 package thermal resistance of 65 K/W under standard PCB mounting conditions.
Technical Context
The TLE42702GATMA1 implements a bandgap-referenced control amplifier driving a series pass transistor with saturation control to maintain regulation across load and line variations. Its reset generator monitors output voltage against a 4.65 V threshold and delivers an open-collector reset signal with programmable delay via external capacitor on pin D.
Protection circuitry includes reverse polarity detection, overtemperature shutdown at ~150 °C junction, short-circuit current limiting (850 mA peak), and transient overvoltage clamping up to 65 V for ≤400 ms-enabling robust operation in 12 V/24 V automotive battery environments with load dump transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.00 V ±2% (4.90–5.10 V); maintains accuracy across 5–550 mA load and 6–26 V input. |
| Max Output Current | 650 mA continuous; current-limited to 850 mA during short-circuit events. |
| Dropout Voltage | 350 mV typical at 550 mA; enables stable 5 V output even at VI = 5.35 V. |
| Reset Threshold | 4.65 V (±0.15 V); triggers open-collector RO low when VQ falls below threshold. |
| Reset Delay | Adjustable via external capacitor on pin D; sets timing before RO asserts after power-up. |
| Input Voltage Range | 6–42 V DC operating; withstands 65 V transients ≤400 ms per ISO 7637-2 Pulse 5a. |
| Thermal Resistance | RthJA = 65 K/W (PG-TO263-5, 80×80 mm² PCB); supports 650 mA at Tj ≤125 °C ambient. |
Pinout & Package
Package: PG-TO263-5 (D²PAK), thermally enhanced surface-mount package with exposed heatsink pad connected internally to GND (pin 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - I | Input supply | Connect directly to ceramic bypass capacitor (≥1 µF) at IC pad; accepts 6–42 V nominal, 65 V transient. |
| 2 - RO | Open-collector reset output | Pulled high to VQ via internal 30 kΩ resistor; sinks current when VQ < 4.65 V; requires external pull-up for logic-high default. |
| 3 - GND | Ground / thermal pad | Reference return and primary thermal path; must be soldered to large copper pour for RthJA compliance. |
| 4 - D | Reset delay capacitor terminal | Connect external capacitor (e.g., 100 nF → ~100 ms delay); sets time between VQ stabilization and RO deassertion. |
| 5 - Q | 5 V regulated output | Delivers up to 650 mA; requires 22 µF low-ESR (<3 Ω) output capacitor for stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Reset Generator | Programmable delay via external capacitor; eliminates need for discrete RC reset circuit in ECU designs. |
| Reverse Polarity Protection | Withstands -42 V input without damage; enables safe connection during service or battery reversal events. |
| Overvoltage Clamping | 65 V/400 ms transient immunity per ISO 7637-2; avoids external TVS diode in many 24 V commercial vehicle applications. |
| AEC-Q100 Qualified | Grade 1 (-40 °C to +125 °C ambient), stress-tested for automotive reliability; qualified for safety-critical power domains. |
| Low Quiescent Current | 1.5 mA at 5 mA load; reduces standby power in always-on modules such as CAN gateways and telematics units. |

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 (TI) | 300 mA output, no reset function, 250 mV dropout, SOT-23-5 package | Lacks reset generation and automotive qualification; suitable only for non-safety, low-current infotainment peripherals | Select only if reset signaling is handled externally and thermal/power requirements are significantly lower. |
| MAX1725EUT+T (Analog Devices) | 200 mA output, adjustable reset threshold, SOT-23-6 package, no overvoltage protection beyond 26 V | Not AEC-Q100 qualified; lacks reverse polarity and 65 V transient protection required for under-hood use | Consider only for cabin-mounted modules where full automotive transient immunity is not mandated. |
Compared with TLV73350PDBVR and MAX1725EUT+T, the TLE42702GATMA1 uniquely combines 650 mA drive, integrated reset with programmable delay, AEC-Q100 Grade 1 qualification, and 65 V/400 ms overvoltage survival-making it the sole choice for high-reliability, high-current automotive power domains requiring self-contained protection and sequencing.

FAQ
What is the maximum allowable input voltage for continuous operation?
The TLE42702GATMA1 supports continuous operation up to 42 V input. It also tolerates 65 V transients for durations ≤400 ms, complying with ISO 7637-2 Pulse 5a for automotive load dump events. Operation above 42 V outside this transient window risks permanent damage.
How is the reset delay time calculated using the external capacitor on pin D?
Reset delay tdelay ≈ 1.1 × Rint × CD, where Rint = 30 kΩ (typical internal resistance) and CD is the capacitor value in farads. For example, a 100 nF capacitor yields ~3.3 ms delay. The exact relationship is validated in Infineon's Application Note AN2019-07.
Does the device require an external pull-up resistor on the RO pin?
No external pull-up is required for basic reset signaling, as pin RO has an internal 30 kΩ resistor connecting to the Q output. However, an external pull-up to a higher voltage rail (e.g., 12 V) may be used if the system requires active-high reset logic or faster rise times than the internal resistor allows.
Can the TLE42702GATMA1 be used in parallel for higher current output?
Parallel operation is not supported. The device lacks current-sharing circuitry or matching tolerance specifications for paralleling. Attempting to parallel units risks thermal imbalance and premature failure due to mismatched dropout voltages and load distribution.
