Product details
Overview
TLS810D1EJV50XUMA1 from Infineon is an AEC-Q100 qualified ultra-low-quiescent-current linear voltage regulator delivering a fixed 5.0 V ±2% output at up to 100 mA, with 9 µA quiescent current, 200 mV typical dropout at full load, and operation across 2.75 V–42 V input range-designed for permanent battery-connected automotive ECUs and sensor supplies.
For engineers reviewing the TLS810D1EJV50XUMA1 datasheet, TLS810D1EJV50XUMA1 pinout, TLS810D1EJV50XUMA1 application, or TLS810D1EJV50XUMA1 equivalent, key selection criteria include cranking-mode support down to 2.75 V input, integrated reset with adjustable delay, enable-controlled <1 µA off-state current, and PG-DSO-8 EP thermal performance with exposed pad grounding.
Technical Context
The TLS810D1EJV50XUMA1 implements a bandgap-referenced LDO architecture with fast transient response enabled by internal compensation and stable operation with only 1 µF ceramic output capacitance (ESR ≤100 Ω). Its tracking region begins at 2.75 V, enabling regulation during cold-cranking conditions where battery voltage dips below nominal levels.
Integrated protection includes current-limiting that activates before thermal shutdown, open-collector reset output with undervoltage detection and programmable delay via external capacitor on pin D, and enable logic with internal pull-down-supporting controlled power sequencing in automotive domain controllers and gateway modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% - ensures stable MCU core/sensor bias under battery voltage fluctuations. |
| Quiescent Current | 9 µA typ. - enables >10-year battery standby in always-on automotive modules. |
| Dropout Voltage | 200 mV @ 100 mA - sustains regulated 5 V output even at 5.2 V input during cranking. |
| Input Voltage Range | 2.75 V to 42 V - covers cold-crank (≤6 V), normal operation (9–16 V), and load-dump (≤42 V). |
| Reset Function | Open-collector RO with adjustable delay via capacitor on D pin - provides configurable power-on reset timing for microcontrollers. |
| Enable Threshold | EN high-level threshold ≥2.0 V - compatible with 3.3 V or 5 V logic control without level-shifting. |
| Thermal Shutdown | Activates at Tj ≥150 °C - protects against sustained overload or poor PCB heatsinking. |
Pinout & Package
Package: PG-DSO-8 EP (exposed thermal pad, RoHS-compliant, AEC-Q100 qualified). Exposed pad must be soldered to GND plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 I | Input | Main VIN connection; requires local 100 nF ceramic decoupling to GND for EMI suppression. |
| 2 N.C. | No Connect | Internally unconnected; must remain floating or tied to GND per layout guidelines. |
| 3 EN | Enable | Active-high digital control input with internal pull-down; drives device ON/OFF with <1 µA off-state current. |
| 4 GND | Ground | Primary reference and return path; connects to exposed pad for thermal conduction. |
| 5 D | Reset Delay Timing | Capacitor node setting reset timeout duration; open if reset not used. |
| 6 RO | Reset Output | Open-collector output asserting low during undervoltage; requires external pull-up for logic-level compatibility. |
| 7 N.C. | No Connect | Internally unconnected; no routing or termination required. |
| 8 Q | Output | Regulated 5 V supply; requires ≥1 µF ceramic output capacitor with ESR ≤100 Ω for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ (9 µA) | Enables direct battery connection in always-on systems without compromising vehicle battery life. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | 300 mA output, 45 µA IQ, SOT-23-5 package, no reset or enable | Lacks reset supervision and enable control; unsuitable for safety-critical or sequenced power domains | Select only for non-automotive, cost-sensitive, high-current applications without sequencing needs |
| TPS7B8250QDGNRQ1 | 150 mA output, 17 µA IQ, enable + reset, HTSSOP-8, 40 V max input | Higher IQ reduces battery lifetime in always-on use; lower 40 V input rating excludes some load-dump scenarios | Prefer where higher output current is needed and 40 V input margin is sufficient; verify cranking behavior at 2.75 V |
Compared with TLV73350PDBVR and TPS7B8250QDGNRQ1, TLS810D1EJV50XUMA1 uniquely balances ultra-low IQ (9 µA), cranking-start capability (2.75 V), integrated reset with programmable delay, and 42 V load-dump tolerance-making it optimal for AEC-Q100-compliant, battery-permanent automotive subsystems.

FAQ
What is the minimum input voltage required for regulation at full 100 mA load?
The TLS810D1EJV50XUMA1 maintains regulation down to 2.75 V input-verified across temperature and process corners. At 100 mA load, output remains within 5.0 V ±2% as long as input stays ≥5.2 V (5.0 V + 200 mV dropout). Below 5.2 V, it enters tracking mode, passing through reduced voltage until reaching the 2.75 V lower limit of functional range.
How is the reset delay time calculated when using an external capacitor on pin D?
Reset delay tDELAY ≈ 0.8 × CD × 1 MΩ, where CD is the capacitor value in farads. For example, a 100 nF capacitor yields ~80 ms delay. The relationship is linear and specified across -40°C to +150°C; capacitor tolerance and temperature coefficient directly impact timing accuracy.
Can the exposed thermal pad be left unconnected in the PCB layout?
No-the exposed pad in the PG-DSO-8 EP package must be soldered to a GND plane with ≥4 thermal vias (0.3 mm diameter) to meet thermal resistance specs and ensure safe 100 mA operation. Leaving it unconnected raises junction temperature by >40°C at full load and risks premature thermal shutdown or parametric shift.
Does the RO pin require an external pull-up resistor, and what value is recommended?
Yes-RO is an open-collector output and requires an external pull-up to a logic-compatible voltage (e.g., 3.3 V or 5 V). A 10 kΩ resistor is recommended: low enough to ensure fast rise time (<1 µs) and noise immunity, high enough to limit current during reset assertion (typically <0.5 mA).
