Product details
Overview
TLE4290DATMA1 from Infineon Technologies is a monolithic 5 V ±2% low-dropout linear voltage regulator with Power Good (PG) monitoring, 450 mA output current capability, and AEC-Q100 qualification for automotive microcontroller supply. It operates from 5.5 V to 42 V input, delivers regulated 5 V output down to 1 V dropout, and features reverse-polarity and short-circuit protection.
For engineers reviewing the TLE4290DATMA1 datasheet, TLE4290DATMA1 pinout, TLE4290DATMA1 application, or TLE4290DATMA1 equivalent, key selection criteria include its programmable PG delay (via external capacitor), 200 µA quiescent current at 1 mA load, 4 K/W junction-to-case thermal resistance, and compliance with automotive environmental stress requirements (−40 °C to +150 °C junction).
Technical Context
The TLE4290DATMA1 integrates a bandgap reference, current-saturation control, and dedicated Power Good supervision circuitry. Its PG output is an open-collector signal with user-configurable delay (10–22 ms typical with 47 nF), triggered by output voltage thresholds of 4.65 V (rising) and 3.65 V (falling).
It employs internal thermal shutdown and foldback current limiting to survive overload, short-circuit, and reverse-battery conditions. The regulator maintains regulation with VI as low as 5.5 V and supports stable operation with ≥22 µF output capacitance (ESR < 5 Ω at 10 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2% (4.9–5.1 V); ensures stable MCU core logic supply under varying load and temperature. |
| Max Output Current | 450 mA continuous; sufficient for mid-tier automotive microcontrollers and peripheral ICs. |
| Dropout Voltage | 250–500 mV at 300 mA; enables operation with minimal headroom (e.g., 5.5 V input → 5.0 V output). |
| Quiescent Current | 200–255 µA at 1 mA load; critical for always-on automotive modules requiring ultra-low standby power. |
| Power Good Thresholds | Rising: 4.65 V typ; falling: 3.65 V typ; enables reliable system reset coordination with MCU internal reset logic. |
| Thermal Resistance | Junction-to-case: 4 K/W; supports high-power dissipation on PCB heatsink without forced airflow. |
| Operating Temp | −40 °C to +150 °C junction; validated for under-hood automotive placement per AEC-Q100 Grade 1. |
Pinout & Package
Package: PG-TO252-5-11 (D-Pak variant with 5-pin leadframe, exposed thermal pad). Pin 3 is internally connected to the heatsink for direct thermal coupling to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input | High-side input terminal; requires local ceramic bypass (100 nF) directly to GND for EMI suppression. |
| 2 (PG) | Power Good Open-Collector Output | Active-low status signal; requires external pull-up resistor (>5 kΩ) to regulated output (Q) for MCU NMI or reset assertion. |
| 3 (GND) | Ground / Thermal Pad | Reference node and primary thermal path; must be soldered to large PCB copper area for thermal management. |
| 4 (D) | Delay Timing Capacitor Terminal | Connects external capacitor (e.g., 47 nF) to GND to set PG delay time (10–22 ms); defines MCU initialization window before valid VQ assertion. |
| 5 (Q) | Regulated Output | 5 V output; requires ≥22 µF bulk capacitor (ESR < 5 Ω) for loop stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Power Good Delay | 10–22 ms via external capacitor on pin D; aligns PG assertion with MCU boot sequence timing. |
| Reverse Polarity Protection | Withstands −42 V input; eliminates need for external series diode in battery-connected systems. |
| Short-Circuit Proof Operation | Foldback current limiting prevents thermal runaway during sustained output shorts. |
| AEC-Q100 Qualified | Grade 1 (−40 °C to +125 °C ambient) with extended life test validation; meets automotive reliability standards. |
| Green Product | RoHS-compliant packaging and lead-free finish; compliant with EU Directive 2011/65/EU. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 5 V automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | Lower IQ (45 µA typ), lower current (300 mA), no PG output, SOT-23-5 package. | Lacks Power Good signaling and automotive qualification; suitable only for non-safety-critical body electronics. | Select when cost and board space are prioritized over functional safety and system-level monitoring. |
| TPS7B6950QDCYRQ1 | 500 mA output, integrated PG, AEC-Q100 Grade 1, but higher dropout (300 mV @ 250 mA) and larger thermal footprint (SOT-223). | Same functional scope but less thermally efficient; requires larger PCB heatsink area than TLE4290's TO252-5. | Select if higher current margin is needed and thermal constraints allow SOT-223 mounting. |
Compared with TLV73350PDBVR and TPS7B6950QDCYRQ1, the TLE4290DATMA1 uniquely combines AEC-Q100 qualification, 450 mA output, programmable PG delay, and TO252-5 thermal performance-making it optimal for space-constrained, high-reliability engine bay applications.

FAQ
What is the minimum input voltage required for regulation?
The TLE4290DATMA1 requires a minimum input voltage of 5.5 V to maintain 5.0 V output regulation. Below this, the output drops linearly with input due to insufficient headroom. This is specified in the Operating Range table (VI,min = 5.5 V) and verified across −40 °C to +150 °C junction temperature.
How is the Power Good delay time calculated?
The Power Good delay time (trd) is determined by the external capacitor connected between pin D and GND. With CD = 47 nF, trd is 10–22 ms (typ. 16 ms). The relationship is approximately linear: doubling CD doubles trd. No resistor is required-only the capacitor sets timing.
Can the PG pin drive a microcontroller reset directly?
Yes-the PG pin is an open-collector output rated for 5 mA sink current and compatible with standard MCU reset inputs. A pull-up resistor (>5 kΩ) to the regulated 5 V output (pin Q) is mandatory. PG asserts LOW when VQ falls below 3.65 V, signaling loss of valid supply to trigger hardware reset.
Is an input capacitor required, and what value is recommended?
Yes-an input capacitor is mandatory for stability and EMI suppression. A 100 nF ceramic capacitor placed directly between pin I and GND is specified in the application diagram. For high-current or long-wire applications, a parallel 1000 µF electrolytic capacitor is recommended to handle bulk energy and reduce line impedance.
