Product details

Overview

TLE4262GMXUMA2 from Infineon Technologies is a 5-V low-dropout linear voltage regulator in PG-DSO-14-30 package, delivering ≥200 mA output current with ±2% output voltage tolerance (4.90–5.10 V), 0.35 V typical dropout at 150 mA, and integrated reset generator with adjustable 4.5 V threshold. It operates from 6–45 V input and is AEC-Q100 qualified for automotive power supply rails feeding microcontrollers.

For engineers reviewing the TLE4262GMXUMA2 datasheet, TLE4262GMXUMA2 pinout, TLE4262GMXUMA2 application, or TLE4262GMXUMA2 equivalent, key selection criteria include reset delay programmability via external capacitor, inhibit-controlled standby current ≤10 µA, thermal shutdown at 150 °C, and stability with 22 µF/≤3 Ω ESR output capacitance.

Technical Context

The TLE4262GMXUMA2 uses a bandgap-referenced control amplifier driving a series pass transistor with saturation control to maintain regulation across load and line variations. Its reset generator monitors output voltage via the RADJ pin and triggers an open-collector RO signal when V_Q falls below the externally set threshold (default 4.5 V).

Reset delay is set by charging/discharging an external capacitor on the D pin between lower (0.35 V) and upper (1.8 V) timing thresholds; inhibit (INH) is TTL-compatible and low-active, reducing quiescent current from 900 µA to <10 µA when asserted.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	5.00 V ±2% (4.90–5.10 V); stable over -40 to +125 °C and 5–150 mA load.
Dropout Voltage	0.35 V typ. at 150 mA; enables regulation down to VI = 5.35 V, critical for cold-crank automotive operation.
Max Input Voltage	45 V; withstands load-dump transients per ISO 7637-2 without external clamping.
Reset Threshold	Adjustable 3.5–4.5 V via RADJ voltage divider; default 4.5 V trigger ensures MCU reset before brownout.
Reset Delay	Programmable via external capacitor on D pin; 17 ms typ. with 100 nF, enabling precise power-on sequencing.
Quiescent Current	≤10 µA in INH-active standby; reduces battery drain in always-on vehicle modules.
Thermal Protection	Automatic shutdown at T_j ≥150 °C; resumes after cooldown-no latch required.

Pinout & Package

PG-DSO-14-30: 14-pin exposed-pad SOIC package with thermal pad (pin 4), RoHS-compliant, AEC-Q100 qualified.

Pin/Terminal	Circuit Role	Design Meaning
1	RO	Open-collector reset output; sinks current when V_Q < threshold-requires external pull-up for µC reset input.
2, 8	N.C.	No internal connection; must remain unconnected per datasheet.
3–5, 10–12	GND	Seven ground terminals; low-inductance return path for power and reset circuits-connect all to common ground plane.
6	D	Reset delay capacitor node; charges/discharges to set reset pulse width-connect to GND via 100 nF ceramic.
7	RADJ	Reset threshold adjust input; voltage divider from Q to GND sets trip point-0 V = 4.5 V, 1.35 V = 3.5 V.
9	Q	Regulated 5 V output; requires ≥22 µF/≤3 Ω ESR ceramic or tantalum capacitor directly at pin for loop stability.
13	I	Main input (6–45 V); bypass with 100 nF ceramic capacitor directly at pin to suppress high-frequency noise.
14	INH	Inhibit control; TTL-low active (≤0.8 V) disables regulator and cuts I_q to <10 µA-used for system sleep mode.

Key Features

Feature	Design Value
Adjustable Reset Threshold	Settable from 3.5 V to 4.5 V via external resistor divider on RADJ-enables compatibility with diverse MCU V_DD tolerances.
Programmable Reset Delay	Externally set via capacitor on D pin-supports configurable power-on reset timing for multi-rail systems.
Ultra-Low Standby Current	<10 µA with INH asserted-meets automotive "parking mode" current budgets (<50 µA total).
Integrated Reverse Polarity Protection	Withstands -42 V input-eliminates need for external series diode in battery-connected applications.
AEC-Q100 Qualified	Grade 1 (-40 to +125 °C) qualification-validates reliability for engine bay and infotainment power supplies.

Applications

Engine Control Unit (ECU) Power Supply

Body Control Module (BCM) Microcontroller Rail

Use Scenario: Powers 5 V microcontroller and CAN transceiver in gasoline/diesel engine management systems subject to 45 V load-dump transients.

IC Role / Device Role / Timing Role: Primary 5 V LDO with integrated reset and inhibit-replaces discrete reset IC + regulator combo.

Use Value: Single-chip solution reduces BOM count and PCB area while meeting ISO 7637-2 pulse immunity and AEC-Q100 requirements.

Use Scenario: Supplies 5 V rail to body controller MCU during vehicle sleep mode with <50 µA total system current.

IC Role / Device Role / Timing Role: Low-quiescent LDO with INH-controlled shutdown-enables deep-sleep state without external power gating.

Use Value: Achieves <10 µA standby current, eliminating need for mechanical relay or high-side switch in always-on BCM designs.

Advanced Driver Assistance Systems (ADAS) Camera Module

Infotainment Head Unit Core Logic Supply

Use Scenario: Regulates 5 V for image sensor and ISP in rear-view camera exposed to under-hood temperature extremes.

IC Role / Device Role / Timing Role: High-temp-stable LDO with thermal shutdown-ensures safe shutdown before silicon damage at 150 °C junction.

Use Value: Built-in overtemperature protection avoids external thermal monitoring circuitry and simplifies thermal design.

Use Scenario: Provides clean 5 V supply to application processor and audio codec in head units with multiple power states.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 5-V automotive LDO with reset applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV70750PDBVR	Lower max input (5.5 V), no reset output, 300 mA output, SOT-23-5 package.	Suitable only for post-regulated 3.3/5 V rails-not for direct battery input.	Select if input is pre-regulated and reset function is handled elsewhere.
MAX16150ATB+T	Higher accuracy (±0.5%), fixed 4.65 V reset, 200 mA, 16-pin TQFN; no inhibit pin.	Lacks INH control and adjustable reset threshold-requires external enable logic.	Prefer when tighter V_OUT tolerance is critical and system-level inhibit is available.

Compared with TLV70750PDBVR and MAX16150ATB+T, the TLE4262GMXUMA2 uniquely combines 45 V input capability, adjustable reset, and low-power inhibit in a single AEC-Q100-qualified device-making it optimal for primary battery-fed automotive LDO applications.

FAQ

What is the minimum input voltage required for regulation?

The TLE4262GMXUMA2 regulates down to VI = V_Q + V_DR, where V_DR is 0.35 V typical at 150 mA. With 5.0 V output, minimum functional input is 5.35 V. Below this, output drops linearly with input-no regulation occurs below 5.2 V per absolute ratings.

How is the reset threshold adjusted using the RADJ pin?

Connect a resistor divider from Q (5 V) to GND, tapping RADJ at the midpoint. When RADJ = 0 V, reset triggers at V_Q = 4.5 V. To set 3.5 V threshold, bias RADJ to 1.35 V-achieved with R1 = 10 kΩ from Q to RADJ and R2 = 22 kΩ from RADJ to GND.

Can the TLE4262GMXUMA2 drive a 220 µF output capacitor?

Yes-the datasheet guarantees stability with output capacitors ≥22 µF and ESR ≤3 Ω at 10 kHz. A 220 µF/low-ESR tantalum or polymer capacitor meets this and improves transient response, though 22–100 µF ceramics are preferred for lowest noise.

Is the RO pin compatible with 3.3 V microcontroller reset inputs?

Yes-RO is open-collector with 30 kΩ internal pull-up to Q. Use an external pull-up to 3.3 V (not 5 V) and ensure the µC reset pin accepts 3.3 V logic levels. The RO sink current is rated for ≥1 mA, sufficient to drive standard CMOS reset inputs.
