Product details
Overview
TLE4263GMXUMA2 from Infineon Technologies is a 5 V fixed-output, low-dropout linear voltage regulator in PG-DSO-14 package, delivering up to 200 mA output current with ±2% output voltage tolerance, 0.35 V typical dropout at 150 mA, and integrated watchdog, reset, and inhibit functions. It operates from 6–45 V input, features reverse polarity and overtemperature protection, and is qualified per AEC-Q100 for automotive power supply rails.
For engineers reviewing the TLE4263GMXUMA2 datasheet, TLE4263GMXUMA2 pinout, TLE4263GMXUMA2 application, or TLE4263GMXUMA2 equivalent, key selection criteria include its adjustable reset threshold (3.5–4.5 V), external reset delay capacitor control, TTL-compatible active-low inhibit input, and open-collector reset output with internal 30 kΩ pull-up.
Technical Context
The TLE4263GMXUMA2 integrates a bandgap reference, error amplifier, series pass transistor with saturation control, and protection logic for overload, reverse polarity, and thermal shutdown. Its reset generator monitors output voltage via the RADJ pin and triggers RO when VQ falls below the threshold-adjustable from 4.5 V (RADJ = GND) down to 3.5 V using an external divider.
Watchdog supervision uses edge-triggered input W to detect microcontroller activity; missing pulses force RO low. Inhibit (INH) enables full shutdown with standby current dropping to ~0 µA. The regulator maintains stability with CQ ≥22 µF and ESR ≤3 Ω at 10 kHz, and supports wide junction temperature range (−40 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 5.00 V ±2% (4.90–5.10 V); stable across 5–150 mA load and 6–28 V input. |
| Max output current | 200 mA continuous; current limiting activates at 201–400 mA to prevent damage. |
| Dropout voltage | 0.35 V typ. at 150 mA; enables operation with VI as low as 5.35 V while maintaining regulation. |
| Reset threshold | Adjustable 3.5–4.5 V via RADJ pin; default 4.5 V when tied to GND. |
| Standby current | ≤10 µA with INH low; drops from 900 µA operating to near-zero quiescent draw. |
| Operating temp | −40 °C to +150 °C junction; validated for under-hood automotive environments. |
| Protection | Integrated reverse polarity, overtemperature, short-circuit, and overload protection. |
Pinout & Package
Package: PG-DSO-14 (exposed pad, RoHS-compliant, thermally enhanced SMD package with 14 leads).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input voltage (VI) | Primary DC input (6–45 V); requires local ceramic decoupling capacitor. |
| 2 | Inhibit (INH) | TTL-compatible, active-low enable; pulls IQ to ~0 µA when low. |
| 3, 4, 13 | GND | Power ground pins; multiple connections reduce impedance and improve thermal dissipation. |
| 5 | Reset delay (D) | Connects external capacitor to set reset pulse width and delay timing. |
| 6 | Reset threshold (RADJ) | Voltage divider input to adjust reset trigger point from 4.5 V down to 3.5 V. |
| 7 | Watchdog (W) | Rising-edge triggered input; missing edges force RO low to reset system. |
| 8 | Output (Q) | Regulated 5 V output; requires ≥22 µF output capacitor with ESR ≤3 Ω. |
| 9 | Reset output (RO) | Open-collector output with internal 30 kΩ pull-up; drives external reset line low on fault. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable reset threshold | Configurable 3.5–4.5 V via external resistor divider on RADJ, enabling precise brown-out detection. |
| Programmable reset delay | Externally set via capacitor on D pin, allowing tailored reset hold time independent of supply ramp rate. |
| Watchdog supervision | Edge-triggered W input provides fail-safe microcontroller monitoring without requiring dedicated timer peripherals. |
| Ultra-low standby current | ≤10 µA in inhibit mode enables long-term battery-backed operation in always-on automotive modules. |
| AEC-Q100 qualified | Qualified to Grade 1 (−40 °C to +125 °C ambient) and extended junction range (−40 °C to +150 °C). |
Applications
| Body Control Module (BCM) | Engine Control Unit (ECU) Power Rail |
|---|---|
|
Use Scenario: Powering microcontrollers and CAN transceivers in vehicle door modules with intermittent battery voltage dips. IC Role / Device Role / Timing Role: Primary 5 V LDO regulator with brown-out reset and watchdog supervision for MCU safety monitoring.

|
Use Scenario: Providing clean, monitored 5 V supply to image signal processors and serializer ICs in rear-view cameras. IC Role / Device Role / Timing Role: Voltage regulator with watchdog input to detect ISP firmware hangs and initiate controlled recovery. Use Value: Open-collector RO output directly interfaces with camera SoC reset pin, eliminating need for external level-shifting or pull-up resistors. |
Use Scenario: Supporting USB PHY, display interface, and audio codec power domains in head units with variable load profiles. IC Role / Device Role / Timing Role: Secondary LDO with programmable reset delay to coordinate multi-rail power sequencing during ignition-on transitions. Use Value: External capacitor on D pin sets 100–500 ms reset hold time, ensuring all subsystems initialize before software boot begins. |
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, 250 mV dropout, no watchdog/reset adjustment; SOT-23-5 package. | Lacks RADJ, D, W, and RO pins; suitable only for basic regulation without supervision. | Select when system-level reset/watchdog is handled externally and space constraints favor SOT-23. |
| MAX16922ATP/V+T | 5 V/250 mA, integrated watchdog and reset, but fixed 4.65 V threshold and no RADJ pin. | Fixed reset point limits adaptability to varying brown-out requirements across vehicle platforms. | Choose when design requires guaranteed drop-in replacement with identical watchdog timing but no threshold tuning needed. |
Compared with TLV73350PDBVR and MAX16922ATP/V+T, the TLE4263GMXUMA2 uniquely combines adjustable reset threshold, programmable delay, and AEC-Q100 Grade 0 qualification in PG-DSO-14-enabling single-chip power supervision where system-level flexibility and under-hood reliability are critical.

FAQ
What is the minimum input voltage required for regulation?
The TLE4263GMXUMA2 requires a minimum input voltage of 6 V to maintain regulated 5 V output. Below this, the device enters dropout mode and output voltage tracks input minus dropout voltage (~0.35 V). Operation below 6 V is not specified and may result in unregulated output or reset assertion.
How does the watchdog function interact with the reset output?
The watchdog input (W) is rising-edge triggered; missing edges within the programmed timeout window cause the reset output (RO) to go low. This action is independent of the voltage-monitoring reset path and remains active even if RADJ is grounded-providing dual-fault detection for MCU lockup and supply brown-out.
Can the reset threshold be set below 3.5 V?
No-the datasheet specifies 3.5 V as the minimum achievable reset threshold using the RADJ pin with an external voltage divider. Attempting lower thresholds risks violating the absolute maximum rating for RADJ voltage (−0.3 V to +6 V) and may cause undefined behavior or damage.
Is thermal derating required for continuous 200 mA operation?
Yes-continuous 200 mA operation in PG-DSO-14 requires PCB layout with thermal relief: footprint-only mounting yields Rthj-a = 112 K/W, limiting max ambient to ~85 °C at full load; adding a 300 mm² copper heat sink reduces Rthj-a to 92 K/W, enabling full-rated current up to 105 °C ambient.
