Product details
Overview
TLE42364GHTMA1 from Infineon Technologies is a low-dropout linear voltage regulator delivering 5 V ±2% output at up to 100 mA, with enable control, reverse polarity protection, and overtemperature shutdown. It operates from 5.5 V to 45 V input in automotive environments and features 0.25 V typical dropout at full load.
For engineers reviewing the TLE42364GHTMA1 datasheet, TLE42364GHTMA1 pinout, TLE42364GHTMA1 application, or TLE42364GHTMA1 equivalent, key selection criteria include its AEC-Q100 qualification, 10 µA shutdown current, thermal shutdown behavior, and SOT223-4 package compatibility with high-temperature under-hood systems.
Technical Context
The TLE42364GHTMA1 integrates a precision bandgap reference, control amplifier, PNP pass transistor with saturation control, and dedicated protection circuitry for overcurrent and overtemperature events. Its enable input (EN) provides logic-level on/off control with 3.5 V turn-on threshold and 0.8 V turn-off threshold.
Stability requires CQ ≥ 10 µF with ESR ≤ 10 Ω; CI is mandatory for line transient suppression. The device maintains regulation across -40 °C to +150 °C junction temperature and exhibits 54 dB PSRR at 100 Hz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2% - stable rail for MCU core/logic supply in automotive ECUs |
| Max Output Current | 100 mA - sufficient for sensor interface ICs and small microcontrollers |
| Dropout Voltage | 0.25 V typ. at 100 mA - enables operation down to 5.25 V input in cold-crank scenarios |
| Shutdown Current | <10 µA at Tj ≤ 100 °C - preserves battery during vehicle sleep mode |
| Input Voltage Range | 5.5 V to 45 V - supports 12 V and 24 V automotive systems including load dump |
| Thermal Shutdown | Active at Tj ≥ 150 °C - prevents permanent damage during sustained overload |
| Enable Threshold | VEN,on = 3.5 V min., VEN,off = 0.8 V max. - compatible with standard 5 V logic and wake-up signals |
Pinout & Package
Package: PG-SOT223-4 (exposed thermal pad), RoHS-compliant, AEC-Q100 qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 5.5–45 V; must be decoupled directly to GND with ceramic capacitor |
| 2 (EN) | Enable control input | High-active logic: ≥3.5 V enables regulator; ≤0.8 V disables and reduces Iq to <10 µA |
| 3 (OUT) | Regulated 5 V output | Delivers up to 100 mA; requires ≥10 µF/ESR ≤10 Ω output capacitor for stability |
| 4 (GND) | Power ground reference | Common return path for IN, EN, and OUT; connects to exposed thermal pad for heat dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Reverse polarity protection | Withstands -30 V input without damage - eliminates need for external series diode in battery-reversed fault conditions |
| Overcurrent limitation | 120–150 mA foldback - limits power dissipation during short-circuit while maintaining safe junction temperature |
| Wide operating temperature | -40 °C to +150 °C junction range - validated for engine bay and transmission control module placement |
| Low-noise regulation | 54 dB PSRR at 100 Hz - suppresses alternator ripple and reduces need for post-regulation filtering |
| Green product compliance | RoHS-compliant, halogen-free, lead-free - meets automotive environmental standards and end-of-life recycling requirements |
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 | 300 mA output, 170 mV dropout, no reverse polarity protection, non-AEC-Q100 | Targeted at consumer/portable designs; lacks automotive fault robustness | Choose only for non-automotive, higher-current, cost-sensitive applications where reverse polarity risk is absent |
| TPS7B6950QDCYRQ1 | 150 mA output, 300 mV dropout, integrated watchdog timer, AEC-Q100 Grade 1 | Includes system supervision features; wider input range (4.5–40 V) | Select when functional safety monitoring (e.g., reset generation) is required alongside regulation |
Compared with TLV73350PDBVR and TPS7B6950QDCYRQ1, the TLE42364GHTMA1 offers unique reverse polarity immunity and lower dropout at 100 mA-critical for legacy 12 V architectures with marginal cold-crank margins-while maintaining AEC-Q100 compliance without added supervision overhead.

FAQ
What is the minimum input voltage required for regulation at full 100 mA load?
The TLE42364GHTMA1 requires VI ≥ 5.25 V to maintain 5.0 V output at 100 mA, based on its 0.25 V typical dropout voltage. Below this, output voltage drops linearly with input; regulation is guaranteed only above 5.5 V per datasheet functional range.
Can the TLE42364GHTMA1 be used without an output capacitor?
No. An output capacitor CQ ≥ 10 µF with ESR ≤ 10 Ω is mandatory for loop stability across -40 °C to +150 °C. Omitting it causes oscillation and unregulated output, risking downstream IC malfunction or latch-up.
Does the enable pin require a pull-up resistor in automotive applications?
No external pull-up is required. When left floating, internal leakage keeps EN near GND, disabling the regulator. For reliable wake-up, connect EN directly to battery via ignition-switched 12 V or use a dedicated wake signal ≥3.5 V.
How does the overtemperature shutdown behave during continuous overload?
At Tj ≥ 150 °C, the IC shuts down output and enters thermal hysteresis mode, restarting only after Tj falls below ~140 °C. This cycle prevents destructive overheating but is not intended for repetitive operation-design must limit power dissipation using heatsinking or derating.
