Product details
Overview
TLE42764EV50XUMA1 from Infineon Technologies is a monolithic low-dropout linear voltage regulator delivering a fixed 5.0 V ±2% output at up to 400 mA, with input voltage range of 5.5–40 V, enable-controlled operation, and integrated reverse polarity, overcurrent, and overtemperature protection. It is qualified per AEC-Q100 for automotive power supply rails in engine control units, body electronics, and ADAS sensors.
For engineers reviewing the TLE42764EV50XUMA1 datasheet, TLE42764EV50XUMA1 pinout, TLE42764EV50XUMA1 application, or TLE42764EV50XUMA1 equivalent, key selection criteria include dropout voltage at 400 mA, quiescent current in enable-off state (<10 µA), thermal performance in PG-SSOP-14 exposed pad package, and functional safety compliance for permanent battery-connected systems.
Technical Context
The TLE42764EV50XUMA1 implements a bandgap-referenced control amplifier driving a pass transistor with saturation control and integrated protection logic. Its architecture supports stable regulation under wide input transients (e.g., load dump up to 40 V) while maintaining tight output accuracy across -40°C to +150°C junction temperature.
Enable functionality uses an internal pull-down resistor and TTL-compatible threshold (VIH ≥ 2.0 V, VIL ≤ 0.8 V), allowing direct microcontroller GPIO interfacing. The device operates without external compensation due to internal stability design optimized for 22 µF/3 Ω ESR ceramic output capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 5.0 V ±2% - ensures compatibility with 5-V MCU peripherals and CAN transceivers without external feedback. |
| Max output current | 400 mA - sufficient to power multiple automotive sensors or small microcontrollers from a single rail. |
| Dropout voltage | Typ. 300 mV @ 400 mA - enables regulation down to 5.3 V input, critical during cold-crank battery conditions. |
| Quiescent current | <10 µA in disable mode - preserves battery life in always-on vehicle modules like telematics or alarm systems. |
| Operating temperature | -40°C to +150°C - validated for under-hood placement per AEC-Q100 Grade 0 requirements. |
| Input voltage range | 5.5 V to 40 V - accommodates 12-V and 24-V automotive systems including load dump surges. |
| Protection features | Reverse polarity, overcurrent limit, overtemperature shutdown - eliminates need for external protection circuitry. |
Pinout & Package
The TLE42764EV50XUMA1 is housed in a PG-SSOP-14 exposed pad package (14-pin shrink small outline package with thermal pad), optimized for high-power-density automotive PCB layouts and enhanced thermal dissipation via soldered exposed pad connection to GND plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5–7 | n.c. | Not connected - may be left floating or tied to GND for mechanical stability; no electrical function. |
| 2 | EN | Enable input - active-high TTL-compatible control; internal pull-down ensures safe default-off state. |
| 4 | GND | Ground reference - primary signal and power return path; connects internally to exposed thermal pad. |
| 8, 10–12, 14 | n.c. | Not connected - electrically isolated pins; no routing required beyond mechanical clearance. |
| 9 | Q | Regulated output - delivers 5.0 V ±2% to load; requires local 22 µF ceramic capacitor with ≤3 Ω ESR. |
| 13 | I | Input - accepts 5.5–40 V unregulated supply; requires direct ceramic decoupling to GND at IC pin. |
| Exposed pad | Thermal pad / GND | Internally bonded to GND - must be soldered to large copper area for thermal management and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Grade 0 (-40°C to +150°C) qualification ensures reliability in engine bay and transmission control applications. |
| Reverse polarity protection | Withstands -42 V input - eliminates risk of damage during battery installation errors or jump-start scenarios. |
| Low quiescent current | <10 µA in disable mode - enables use in always-on domains such as vehicle wake-up circuits and intrusion detection. |
| Integrated thermal shutdown | Activates at ~170°C junction temperature - prevents catastrophic failure during sustained overload or poor heatsinking. |
| Stable with ceramic output caps | Validated for 22 µF/3 Ω ESR - reduces BOM count and board space vs. tantalum or electrolytic alternatives. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | Lower max current (300 mA), wider input range (1.4–5.5 V), no reverse polarity protection | Targeted at low-voltage portable electronics, not automotive-grade environments | Select only for non-automotive, low-power, cost-sensitive designs where reverse protection and AEC-Q100 are unnecessary. |
| TPS7B8750QKVURQ1 | Higher precision (±1%), lower dropout (250 mV @ 400 mA), same AEC-Q100 Grade 1 rating | Designed for ASIL-B functional safety systems; includes power-good flag and tighter thermal specs | Prefer when functional safety certification (ISO 26262) or tighter output tolerance is required; higher cost justified by safety compliance. |
Compared with TLV73350PDBVR and TPS7B8750QKVURQ1, the TLE42764EV50XUMA1 offers balanced performance for mainstream automotive applications-delivering robust reverse polarity protection and 150°C operation at lower system cost than safety-certified alternatives, while exceeding the voltage and thermal capability of consumer-grade LDOs.

FAQ
What is the minimum input voltage required for regulation at full 400 mA load?
The TLE42764EV50XUMA1 requires a minimum input voltage of 5.5 V to maintain 5.0 V ±2% regulation at 400 mA. This corresponds to a typical dropout voltage of 300 mV at that load, verified across -40°C to +150°C junction temperature per datasheet Section 4.1.
Can the EN pin be left unconnected, or does it require a defined logic level?
The EN pin must not be left floating. It features an internal pull-down resistor (~100 kΩ), ensuring default-disable behavior when unconnected. For reliable operation, tie EN to VI (≥2.0 V) to enable or to GND (≤0.8 V) to disable-no external pull-up/down is required unless noise immunity is critical.
Is the exposed thermal pad electrically connected, and how should it be handled on the PCB?
Yes, the exposed pad is internally connected to GND. It must be soldered to a dedicated GND copper pour using at least 9 solder paste vias (0.3 mm diameter) to a solid inner-layer GND plane. This ensures both thermal conduction (RθJA ≈ 50 K/W) and EMI suppression, as specified in Infineon Package Information Document PG-SSOP-14.
Does the TLE42764EV50XUMA1 support adjustable output voltage configurations?
No. The 'EV50' suffix denotes the fixed 5.0 V output version. Adjustable variants (e.g., TLE42764GV) use the VA pin for external resistor divider feedback. The EV50 variant has VA internally tied and is not configurable-output is factory-trimmed to 5.0 V ±2% across temperature and line/load conditions.
