Product details
Overview
TLS710B0EJV50XUMA1 from Infineon Technologies is a low-dropout linear voltage regulator delivering 5 V ±2% output with up to 100 mA load current, 200 mV typical dropout at full load, 36 µA quiescent current, and operation across 4.0–40 V input range - designed for automotive battery-supplied systems with start-stop capability.
For engineers reviewing the TLS710B0EJV50XUMA1 datasheet, TLS710B0EJV50XUMA1 pinout, TLS710B0EJV50XUMA1 application, or TLS710B0EJV50XUMA1 equivalent, key selection criteria include AEC-Q100 qualification, thermal shutdown behavior, enable-controlled power sequencing, and stability with 1 µF ceramic output capacitor in harsh-temperature environments.
Technical Context
The TLS710B0EJV50XUMA1 implements a bandgap-referenced feedback loop controlling an internal PNP pass transistor, enabling regulation down to 4.0 V input (extended dropout region) while maintaining 5 V output. Its fast regulation architecture minimizes output capacitance requirements without external compensation.
Enable functionality uses an integrated pull-down resistor and accepts 0–40 V logic-compatible input; overtemperature shutdown and foldback current limiting operate autonomously without external circuitry. Thermal protection triggers at ~150°C junction temperature and enables auto-restart after cooldown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2% - ensures stable MCU/ASIC core supply within automotive-grade tolerance bands |
| Max Output Current | 100 mA - sufficient for powering CAN transceivers, sensor interfaces, or small microcontrollers |
| Dropout Voltage | 200 mV typ. @ 100 mA - supports regulation during cold-crank (≥4.0 V input), critical for start-stop systems |
| Quiescent Current | 36 µA - enables always-on battery-connected modules (e.g., alarm controllers, telematics) with minimal parasitic drain |
| Input Voltage Range | 4.0 V to 40 V - covers full automotive battery transient profile including load dump (40 V) and cranking (4.0 V) |
| Operating Temp | −40°C to +150°C - qualified for under-hood placement per AEC-Q100 Grade 0 |
| Output Cap Requirement | 1 µF ceramic - eliminates need for large tantalum or electrolytic capacitors, reducing board area and cost |
Pinout & Package
Package: PG-DSO-8 EP (exposed thermal pad), RoHS-compliant, AEC-Q100 qualified surface-mount package with 1.27 mm pitch and 6.0 × 4.9 mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input Compensation | Optional input-side capacitor connection point to suppress line transients; not power input |
| 2 (EN) | Enable Control | Logic-level input with internal pull-down; high = active regulation, low = shutdown (IQ < 1 µA) |
| 3 (GND) | Ground Reference | Main signal and power return path; must be low-impedance connection to PCB ground plane |
| 4–7 (n.c.) | No Connect | Internally unconnected pins; may be left floating or tied to GND for mechanical stability |
| 8 (Q) | Regulated Output | 5 V regulated power output; requires 1 µF ceramic capacitor placed adjacent to pin |
| Exposed Pad | Thermal Interface | Electrically connected to GND; must be soldered to thermal copper pour for RthJA ≤ 59 K/W |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Grade 0 (−40°C to +150°C) qualification confirmed - meets automotive reliability and stress-test requirements |
| Fast Regulation Loop | Stable with only 1 µF ceramic output capacitor - reduces BOM count and improves transient response vs. legacy LDOs |
| Extended Dropout Region | Regulates down to 4.0 V input - maintains 5 V output during engine cranking when battery dips below 6 V |
| Integrated Protection | Auto-recovering overtemperature shutdown + foldback current limit - prevents latch-up during sustained short-circuit faults |
| Low Quiescent Power | 36 µA operating IQ - enables >1-year battery life in always-on vehicle modules powered directly from 12 V battery |
Applications

Use Value: Foldback current limit prevents thermal runaway during actuator stall; auto-restart avoids permanent lockout after overtemp event. |
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, 500 mV dropout, −40°C to +125°C, no AEC-Q100 qualification | Targeted at industrial/commercial portable devices, not automotive under-hood use | Select only if higher current and non-automotive qualification are acceptable |
| TPS7B6750QPWPRQ1 | 150 mA output, 300 mV dropout, AEC-Q100 Grade 1 (−40°C to +125°C), 45 µA IQ | Limited to cabin-temperature zones; lacks Grade 0 qualification for engine bay | Prefer for dashboard or center-console applications where ambient temp stays ≤125°C |
Compared with TLV73350PDBVR and TPS7B6750QPWPRQ1, TLS710B0EJV50XUMA1 uniquely combines Grade 0 AEC-Q100 qualification, 4.0 V minimum input, and 36 µA IQ - making it the only choice for battery-connected, under-hood, start-stop-capable automotive systems requiring guaranteed 150°C operation.

FAQ
Is TLS710B0EJV50XUMA1 pin-compatible with other Infineon OPTIREG™ LDOs?
No - TLS710B0EJV50XUMA1 uses a unique PG-DSO-8 EP pinout with dedicated Input Compensation (Pin 1) and four no-connect pins (4–7). It is not pin-compatible with TLS850B, TLS820B, or TLS715 series devices, which use different pin assignments and thermal pad configurations.
What is the maximum allowable PCB trace length between the output capacitor and Pin 8 (Q)?
The output capacitor must be placed within 2 mm of Pin 8 (Q) and the exposed thermal pad, with direct low-inductance connections to GND. Longer traces increase ESR/ESL, risking instability or overshoot during load transients - verified in Infineon's layout guidelines for Rev. 1.01 datasheet Figure 6.1.
Does the Enable (EN) pin require external pull-up for automotive wake-up signaling?
No - Pin 2 (EN) has an integrated pull-down resistor (~100 kΩ), so it defaults to OFF. A microcontroller GPIO or discrete switch can drive EN high (≥2.0 V) to activate regulation. No external pull-up is needed unless active-low wake-up logic is implemented via external inverter.
Can TLS710B0EJV50XUMA1 replace a 78L05 in existing automotive designs?
No - although both deliver 5 V, TLS710B0EJV50XUMA1 is not drop-in compatible: it requires enable control, has different pinout (PG-DSO-8 vs. TO-92/SOT-89), lacks built-in reverse-polarity protection, and needs explicit thermal pad soldering. Redesign of PCB layout, enable logic, and thermal management is mandatory.
