Product details
Overview
TLE4285GHTSA1 from Infineon Technologies is a 5 V fixed-output linear voltage regulator in PG-SCT-595-5 package, delivering up to 15 mA output current with ±4% output accuracy, 0.6–1.1 V dropout, and integrated power fail (PF) open-collector output. It operates from 6–42 V input across –40 °C to +150 °C, featuring short-circuit and overtemperature protection for automotive body electronics.
For engineers reviewing the TLE4285GHTSA1 datasheet, TLE4285GHTSA1 pinout, TLE4285GHTSA1 application, or TLE4285GHTSA1 equivalent, key selection criteria include its AEC-Q100 qualification, internal 50 kΩ PF pull-up to VQ, 100 µA typical quiescent current, and mandatory 1 µF/≤10 Ω ESR output capacitor for stability.
Technical Context
The TLE4285GHTSA1 integrates a bandgap reference, error amplifier, pass transistor, and thermal shutdown circuit in a monolithic IC. Its power fail comparator monitors VQ against a threshold of VQ,nom − 50 mV and drives PF low when under-voltage occurs.
Regulation is maintained via internal feedback with load regulation ≤10 mV (0–10 mA) and line regulation ≤10 mV (6–42 V input). PSRR is 60 dB at 100 Hz, and the device uses pin 2 and 5 as internally tied ground terminals for thermal and noise performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±4% (4.8–5.2 V over full temp/load range) |
| Max Input Voltage | 42 V (absolute max 45 V; supports 24 V automotive systems) |
| Dropout Voltage | 0.8 V typ at 10 mA (enables operation down to 5.8 V input) |
| Quiescent Current | 100 µA typ (low standby power for always-on vehicle modules) |
| Power Fail Threshold | VQ,nom − 50 mV (detects output collapse before system reset) |
| Thermal Shutdown | Activates at Tj ≥ 150 °C (protects against sustained overload) |
| Output Capacitor | 1 µF min, ESR ≤ 10 Ω (ensures loop stability; no ceramic bypass required) |
Pinout & Package
Package: PG-SCT-595-5 - 5-pin SMD package with exposed thermal pad, footprint optimized for high-temperature automotive PCBs and thermal resistance Rthj-a = 55 K/W on 40×40 mm² copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PF) | Open-collector power fail indicator | Pulled low when VQ drops below nominal −50 mV; internal 50 kΩ pull-up to VQ |
| 2 (GND) | Ground reference and thermal path | Internally connected to pin 5; must be soldered to large copper pour for thermal management |
| 3 (I) | Unregulated input supply | Accepts 6–42 V; requires local 100 nF decoupling per datasheet Figure 3 |
| 4 (Q) | Regulated 5 V output | Must connect ≥1 µF/≤10 Ω ESR capacitor directly to GND (pins 2/5) for stability |
| 5 (GND) | Secondary ground terminal | Electrically tied to pin 2; improves noise immunity and thermal dissipation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Grade 0 (−40 °C to +150 °C junction), certified for safety-critical automotive use |
| Integrated PF comparator | Eliminates external monitoring circuitry; reduces BOM count by one comparator + resistor divider |
| Short-circuit protected output | Self-limiting current prevents latch-up during wiring faults or connector shorts |
| RoHS-compliant green packaging | Halogen-free, lead-free PG-SCT-595-5 package compliant with EU Directive 2011/65/EU |
| Low thermal resistance | Rthj-pin = 30 K/W to pin 5 enables >1 W dissipation with minimal heatsinking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 5 V automotive linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | Lower IQ (40 µA), lower max input (6.5 V), no PF output, SOT-23-5 package | Not AEC-Q100 qualified; limited to non-safety 5 V rails in infotainment accessories | Select only for cost-sensitive, low-temp, non-automotive designs requiring ultra-low IQ |
| MC78L05ACPG | Higher dropout (1.7 V), no PF, wider tolerance (±5%), TO-92 package, no AEC qualification | Lacks thermal robustness and fault signaling; unsuitable for under-hood or high-reliability use | Use only as legacy drop-in where space and temperature margins allow |
Compared with TLV73350PDBVR and MC78L05ACPG, the TLE4285GHTSA1 uniquely combines AEC-Q100 Grade 0 rating, integrated PF signaling, and 42 V input capability-making it the only choice for new automotive body electronics requiring functional safety-aware power supervision.

FAQ
What is the minimum input voltage required for regulation?
The TLE4285GHTSA1 requires a minimum input voltage of 6 V to maintain 5 V output regulation under all operating conditions. Below this, the output voltage drops linearly with input due to insufficient headroom for the internal pass element and reference circuitry.
Can the PF pin drive an LED directly?
No-the PF pin is an open-collector output rated for ≤500 µA sink current. Driving even a low-current LED (typically ≥2 mA) would exceed its capability and cause unreliable switching or damage. An external NPN transistor or buffer IC is required for LED interfacing.
Is an input capacitor required?
Yes-a 100 nF ceramic capacitor between pin 3 (I) and pins 2/5 (GND) is mandatory per datasheet Figure 3. It suppresses high-frequency noise and prevents oscillation caused by input trace inductance, especially in automotive harness environments.
Does the device require a heatsink in standard PCB layout?
No-when mounted on a 40×40 mm² copper area (≥1.5 oz), the PG-SCT-595-5 package achieves Rthj-a = 55 K/W. At 15 mA output and 13.5 V input, power dissipation is ~127 mW, resulting in <7 °C junction rise above ambient-well within safe limits without added heatsinking.
