Product details
Overview
TLS715B0EJV50XUMA1 from Infineon Technologies is an AEC-Q100 qualified low-dropout linear voltage regulator delivering a precise 5 V ±2% output at up to 150 mA, with 36 µA quiescent current and 200 mV typical dropout at 100 mA - designed for automotive battery-connected systems requiring start-stop compatibility and thermal robustness up to 150°C.
For engineers reviewing the TLS715B0EJV50XUMA1 datasheet, TLS715B0EJV50XUMA1 pinout, TLS715B0EJV50XUMA1 application, or TLS715B0EJV50XUMA1 equivalent, key selection criteria include input voltage range (4.0–40 V), ultra-low IQ, stability with 1 µF output capacitor, enable control logic, and integrated overtemperature/current protection in PG-DSO-8 EP package.
Technical Context
The TLS715B0EJV50XUMA1 employs a bandgap-referenced error amplifier driving a PMOS pass transistor, enabling regulation across a wide input range while maintaining tight output tolerance. Its fast regulation loop supports stable operation with only 1 µF ceramic output capacitance and ESR ≤5 Ω at 10 kHz.
Enable functionality uses an integrated pull-down resistor; logic-high EN (>2.0 V) activates regulation, while logic-low disables output and reduces IQ to <1 µA. Protection circuitry includes foldback current limiting and thermal shutdown with automatic restart after cooldown - critical for automotive fault resilience.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2% - ensures reliable 5 V rail for MCU, CAN transceivers, and sensors under load and temperature variation. |
| Max Output Current | 150 mA - sufficient for powering multiple automotive ECUs' logic and interface ICs from single regulator. |
| Quiescent Current | 36 µA typ. - enables always-on functionality in vehicle body control modules without excessive battery drain. |
| Dropout Voltage | 200 mV typ. at 100 mA - allows regulation down to 5.2 V input, supporting cold-crank and start-stop operation. |
| Input Voltage Range | 4.0 V to 40 V - covers full automotive battery range including load dump (40 V transient) and deep discharge (4 V). |
| Operating Temp | −40°C to +150°C junction - validated for under-hood placement per AEC-Q100 Grade 0 requirements. |
| Output Cap Requirement | 1 µF ceramic, ESR ≤5 Ω - eliminates need for large tantalum or electrolytic capacitors, reducing BOM cost and footprint. |
Pinout & Package
Package: PG-DSO-8 EP (exposed pad), RoHS-compliant, thermally enhanced surface-mount package with 1.27 mm pitch and GND-connected exposed pad for improved heat dissipation (RthJC = 13 K/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input Compensation | Optional compensation node for line transient rejection; connect small capacitor to GND near IC for improved PSRR. |
| 2 (EN) | Enable Input | Active-high digital control with internal pull-down; >2.0 V enables regulation, <0.8 V disables output and cuts IQ to <1 µA. |
| 3 (GND) | Ground Reference | Main power return path; must be low-impedance connection to PCB ground plane and exposed pad. |
| 4–7 (n.c.) | No Connect | Internally unconnected; may be left floating or tied to GND for mechanical stability and thermal conduction. |
| 8 (Q) | Regulated Output | 5 V regulated supply; requires 1 µF ceramic capacitor with ESR ≤5 Ω placed within 3 mm of pin for stability. |
| Pad (EP) | Thermal Pad | Exposed copper pad; must be soldered to ≥300 mm² GND copper area on PCB to achieve RthJA ≤71 K/W. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Grade 0 (−40°C to +150°C) qualification confirmed - suitable for safety-critical automotive power domains. |
| Ultra-Low Quiescent Current | 36 µA typ. - enables >1-year battery standby in always-on telematics or gateway modules without recharge. |
| Start-Stop Compatible | Operates down to 4.0 V input - maintains regulation during engine cranking where battery dips below 6 V. |
| Single-Capacitor Stability | Stable with 1 µF ceramic output cap - eliminates ESR tuning and simplifies layout vs. legacy LDOs requiring 10–22 µF. |
| Integrated Protection | Current limiting + thermal shutdown with auto-restart - prevents latch-up during short-circuit or overheating events. |
Applications
| Body Control Module (BCM) | Automotive Gateway |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-IQ automotive LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR (TI) | 300 mA output, 40 µA IQ, 250 mV dropout at 300 mA, SOT-23-5 package, not AEC-Q100 qualified. | Lacks automotive qualification and thermal rating; limited to cabin/non-safety applications. | Select when higher current is needed and AEC-Q100 is not required; verify thermal derating in enclosed environments. |
| MAX1725EUT+T (Analog Devices) | 150 mA output, 12 µA IQ, 300 mV dropout at 150 mA, SOT-23-5, AEC-Q100 Grade 2 (−40°C to +105°C). | Lower max junction temperature limits use in high-ambient under-hood locations. | Prefer for cost-sensitive cabin modules where 105°C ambient suffices; avoid for engine bay or transmission control units. |
Compared with TLV73350PDBVR and MAX1725EUT+T, TLS715B0EJV50XUMA1 uniquely combines AEC-Q100 Grade 0 qualification, 150°C operation, and 1 µF stability - making it the only choice for thermally demanding, safety-relevant automotive LDO applications requiring long-term reliability.

FAQ
Is TLS715B0EJV50XUMA1 pin-compatible with other Infineon OPTIREG LDOs?
No - TLS715B0EJV50XUMA1 uses a unique PG-DSO-8 EP pinout with four no-connect pins and dedicated input compensation (I) and enable (EN) terminals. It is not pin-compatible with TLS850Bxx or TLS725Bxx families, which use different packages and pin assignments.
Can TLS715B0EJV50XUMA1 operate without an input capacitor?
Yes - an input capacitor is not required for stability, but Infineon recommends a 1–10 µF ceramic capacitor close to the I pin to suppress battery line transients and improve PSRR, especially in direct-battery-connected automotive applications.
What is the maximum allowable PCB copper area for the exposed pad?
There is no upper limit - larger GND copper areas reduce thermal resistance. Infineon specifies RthJA = 71 K/W with 300 mm², 59 K/W with 600 mm², and 46 K/W with 2s2p board. Thermal performance improves monotonically with increased heatsink area and via count.
Does the enable pin require external pull-up for automotive wake-up functionality?
No - EN has an integrated pull-down resistor (~100 kΩ). For wake-up, the host MCU or system controller drives EN high (≥2.0 V); no external pull-up is needed, simplifying design and eliminating leakage paths during sleep mode.
