Product details
Overview
TLE4262GXUMA2 from Infineon is a 5 V automotive-grade 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 dropout at 150 mA, and adjustable reset threshold (4.5 V default, down to 3.5 V via external divider). It features TTL-compatible inhibit input, open-collector reset output, overtemperature and short-circuit protection, and operates from 6 V to 45 V input across −40 °C to +150 °C junction temperature - used for powering microcontrollers and sensors in engine control units.
For engineers reviewing the TLE4262GXUMA2 datasheet, TLE4262GXUMA2 pinout, TLE4262GXUMA2 application, or TLE4262GXUMA2 equivalent, key selection considerations include its AEC-Q100 qualification, adjustable reset delay via external capacitor, standby current as low as 0 µA in inhibit mode, and integrated reverse polarity protection - critical for robust 12 V/24 V automotive power rail design.
Technical Context
The TLE4262GXUMA2 uses a bandgap-referenced control amplifier driving a series pass transistor with saturation control to maintain regulation across wide load and input voltage ranges. Its reset generator monitors output voltage via the RADJ pin and triggers a delayed open-collector reset signal when VQ falls below the threshold, with timing set by an external capacitor on the D pin.
It integrates multiple protection circuits: thermal shutdown activates above 150 °C junction temperature; reverse polarity protection blocks conduction when input is negative; and short-circuit current limiting holds output current at ~250 mA maximum. The INH pin enables full shutdown with <1 µA quiescent current, while internal 30 kΩ pull-up on RO supports standard reset logic interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 5.00 V ±2% - stable supply for 5 V logic, MCU cores, and analog sensors under load and temperature variation |
| Max output current | 200 mA - sufficient for powering small ECUs, CAN transceivers, or sensor signal chains |
| Dropout voltage | 0.35 V at 150 mA - enables operation down to 5.35 V input, supporting cold-crank scenarios in 12 V systems |
| Reset threshold | 4.5 V (adjustable to 3.5 V) - configurable brown-out detection for system-level power sequencing |
| Standby current | 0 µA typical in inhibit mode - eliminates parasitic drain in vehicle sleep modes |
| Operating temp | −40 °C to +150 °C - qualified for under-hood automotive environments per AEC-Q100 Grade 0 |
| Input voltage range | 6 V to 45 V - compatible with 12 V and 24 V battery systems including load dump transients |
Pinout & Package
Package: PG-DSO-14 (14-pin exposed pad SOIC variant, RoHS-compliant, thermally enhanced for automotive power dissipation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RO) | Open-collector reset output | Pulls low when VQ drops below threshold; internally pulled up via 30 kΩ to VQ - interfaces directly with MCU reset inputs |
| 3–5, 10–12 (GND) | Ground terminals | Multiple low-impedance GND connections reduce noise and improve thermal dissipation across PCB footprint |
| 6 (D) | Reset delay capacitor node | Connects external capacitor to GND to set reset pulse delay time (e.g., 17 ms with 100 nF) |
| 7 (RADJ) | Reset threshold adjust input | Voltage divider from VQ to GND sets trip point; 0 V = 4.5 V, scaling allows 3.5 V minimum |
| 9 (Q) | Regulated 5 V output | Requires ≥22 µF output capacitor with ≤3 Ω ESR at 10 kHz for stability and transient response |
| 13 (I) | Input voltage | Accepts 6–45 V; requires local ceramic decoupling capacitor placed directly at pin |
| 14 (INH) | Inhibit control input | TTL-compatible, active-low; drives IC into ultra-low-power state (<1 µA) when pulled low |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable reset threshold | Configurable from 4.5 V down to 3.5 V using external resistor divider - enables precise brown-out detection matching system requirements |
| Programmable reset delay | Externally set via capacitor on D pin (e.g., 17 ms with 100 nF) - prevents false resets during brief transients |
| Ultra-low inhibit current | Typical 0 µA quiescent current when INH = low - meets automotive ISO 16750-2 sleep-mode leakage limits |
| Integrated reverse polarity protection | Blocks conduction if input is connected with reversed polarity - eliminates need for external diode in harsh environments |
| AEC-Q100 qualified | Qualified to Grade 0 (−40 °C to +150 °C) - validated for engine control, transmission, and body electronics applications |
Applications
| Engine Control Unit (ECU) Power Supply | Body Control Module (BCM) Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout automotive voltage regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | 300 mA output, 250 mV dropout, no reset function, non-automotive grade (no AEC-Q100) | Lacks reset generation, thermal shutdown, and reverse polarity protection - unsuitable for safety-critical automotive use | Select only for cost-sensitive non-automotive industrial applications requiring higher current but no functional safety features |
| TPS7B6950QDCYRQ1 | 150 mA output, 300 mV dropout, fixed 4.65 V reset threshold, AEC-Q100 Grade 1 (−40 °C to +125 °C) | Lower max current and narrower temp range; reset not adjustable - limits flexibility in high-temp under-hood designs | Prefer where board space is constrained (SOT-23 package) and reset adjustment is unnecessary; verify thermal margin at 150 °C |
Compared with TLV73350PDBVR and TPS7B6950QDCYRQ1, the TLE4262GXUMA2 uniquely combines 200 mA capability, adjustable reset, −40 °C to +150 °C operation, and full automotive protection suite - making it the only option qualified for Grade 0 engine bay deployment with system-level reset coordination.

FAQ
What is the minimum input voltage required for regulation?
The TLE4262GXUMA2 requires a minimum input voltage of 5.35 V to maintain 5.0 V output at 150 mA load, based on its 0.35 V dropout specification. Below this, regulation is lost and output follows input minus drop. Input must exceed 6 V across full temperature and load range per functional specifications.
How is the reset delay time calculated?
Reset delay is determined by the RC time constant formed between the external capacitor on pin D and the internal charge current of 6–15 µA. With a 100 nF capacitor, typical delay is 17 ms. Exact timing depends on capacitor tolerance and temperature coefficient; design guidance is provided in Infineon Application Note AN2018-05.
Can the reset threshold be set below 3.5 V?
No - the datasheet specifies 3.5 V as the minimum achievable reset threshold when RADJ is driven by a voltage divider. This limit arises from the internal reference comparator's lower bound (1.26 V threshold at RADJ), and attempting lower values risks unreliable reset assertion or failure to trigger.
Is an input capacitor mandatory?
Yes - a ceramic input capacitor must be placed directly at pin 13 (I) to suppress high-frequency noise and prevent oscillation due to PCB trace inductance. Infineon recommends ≥1 µF X7R with ESR < 100 mΩ; adding a 1 Ω series resistor improves damping of LC resonance.
