Product details

Overview

TLE42662GNTMA1 from Infineon Technologies is a monolithic low-drop fixed-voltage regulator in PG-SOT223-4 package, delivering 5.0 V ±2% (up to 50 mA) or ±3% (up to 150 mA), with 150 mA output current capability, <1 µA quiescent current in OFF mode, and inhibit-controlled ON/OFF switching. It operates across -40 °C to +150 °C junction temperature and supports automotive microprocessor power rails under 45 V input.

For engineers reviewing the TLE42662GNTMA1 datasheet, TLE42662GNTMA1 pinout, TLE42662GNTMA1 application, or TLE42662GNTMA1 equivalent, key selection criteria include its AEC-Q100 qualification, ultra-low OFF-mode current, 0.25 V typical dropout at 100 mA, integrated overtemperature protection, and compatibility with ceramic output capacitors ≥10 µF (ESR ≤4 Ω).

Technical Context

The TLE42662GNTMA1 implements a bandgap-referenced control amplifier with internal temperature sensing and saturation-based overtemperature protection. Its inhibit logic uses an integrated 1 MΩ pull-down resistor and requires ≥3.5 V on INH to enable regulation.

Dropout voltage is defined as VI − VQ when VQ drops 100 mV below nominal; for the 5 V version, it is ≤0.5 V at 100 mA. SOA protection reduces max output current above 25 V input to prevent thermal runaway.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	5.0 V ±2% (5–50 mA load); ±3% (5–150 mA); enables stable MCU core supply under wide VIN
Max Output Current	150 mA continuous; internally limited; supports automotive sensors and small logic rails
Quiescent Current	<1 µA (INH = 0 V); 40 µA typ (INH = 5 V, IQ = 100 µA); critical for always-on vehicle modules
Dropout Voltage	0.25 V typ (IQ = 100 mA); allows operation down to VI = 5.25 V; minimizes heat dissipation
Input Voltage Range	5.5 V to 45 V; accommodates cold-crank (≥4.5 V) and load-dump (≤45 V) transients per ISO 7637
Junction Temp Range	−40 °C to +150 °C; qualified for engine bay and transmission control unit placement
Protection Features	Overtemperature shutdown, reverse-polarity immunity, short-circuit current limiting

Pinout & Package

Package: PG-SOT223-4 - thermally enhanced surface-mount package with exposed thermal pad (Pin 4 = GND), footprint compatible with JEDEC MO-178AB, R_thj-a = 81 K/W (worst-case PCB layout).

Pin/Terminal	Circuit Role	Design Meaning
1 (I)	Input voltage supply	Accepts 5.5–45 V; requires local 100 nF ceramic capacitor to ground for stability
2 (INH)	Inhibit control input	CMOS-compatible enable: ≥3.5 V = ON; ≤0.8 V = OFF; internal 1 MΩ pull-down ensures default OFF state
3 (Q)	Regulated output	5.0 V source; requires ≥10 µF output capacitor (ESR ≤4 Ω) for loop stability and transient response
4 (GND)	Power ground / thermal pad	Primary return path and thermal conduction node; must be soldered to large copper pour for thermal management

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for automotive applications requiring operation from −40 °C to +125 °C ambient (T_j up to 150 °C)
Inhibit-controlled ON/OFF	Enables system-level power sequencing and sleep-mode current reduction without external FET or logic
Ultra-low OFF-mode current	<1 µA ensures battery drain remains negligible during vehicle off-state (e.g., key-off, alarm active)
Low-drop architecture	0.25 V typical dropout at 100 mA allows use with marginal input voltages common in 12 V automotive systems
Reverse-polarity protection	Withstands −42 V input without damage; eliminates need for external series diode in battery-connected designs

Applications

IC Role / Device Role / Timing Role: Local post-regulator providing clean, stable 5 V to analog front-ends under 45 V load-dump conditions.

Use Value: Withstands 150 °C junction temperature and rejects >68 dB of 100 Hz ripple-ensuring sensor ADC accuracy remains unaffected by alternator noise.

Transmission Control Unit (TCU)

Advanced Driver Assistance Systems (ADAS) Camera Module

Use Scenario: Delivering regulated 5 V to solenoid drivers and gear-position Hall-effect sensors during aggressive shift cycles.

IC Role / Device Role / Timing Role: Fault-tolerant voltage source with overtemperature and short-circuit protection activated within microseconds.

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-drop automotive voltage regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV73350PDBVR	300 mA output, 250 mV dropout at 300 mA, no inhibit pin, not AEC-Q100 qualified	Suitable for non-automotive industrial controllers; lacks reverse-polarity and overtemperature protection	Select only for cost-sensitive, non-automotive designs where full AEC compliance is unnecessary
TPS7B6750QPWPRQ1	500 mA output, 300 mV dropout at 500 mA, integrated watchdog timer, AEC-Q100 Grade 1	Supports higher-current loads (e.g., radar SoCs); adds fault reporting via ST pin	Prefer when system-level diagnostics and >150 mA delivery are required alongside inhibit control

Compared with TLV73350PDBVR and TPS7B6750QPWPRQ1, the TLE42662GNTMA1 offers the lowest OFF-mode current (<1 µA) and proven robustness in harsh automotive transients-making it optimal for always-on modules where battery preservation and reliability outweigh raw current capacity.

FAQ

What is the minimum input voltage required for regulation at full 150 mA load?

The minimum input voltage is V_Q + V_Dr = 5.0 V + 0.5 V = 5.5 V, per datasheet Table 3 and Figure 3. At 100 mA, typical dropout is 0.25 V, allowing stable regulation down to 5.25 V. Below 5.5 V, output collapses under full load due to SOA derating above 25 V input.

Can the TLE42662GNTMA1 be used with ceramic output capacitors?

Yes-datasheet explicitly specifies ≥10 µF ceramic output capacitors with ESR ≤4 Ω at 10 kHz. Tantalum and multilayer ceramic capacitors (MLCC) are both supported; no electrolytic requirement exists. Stability is guaranteed with this configuration per Figure 3 and Table 3.

Is the INH pin 5 V tolerant when driven from a 5 V microcontroller GPIO?

Yes-the absolute maximum INH voltage is +45 V (Table 2), and typical inhibit-on threshold is 3.5 V with 4–8 µA input current at 5 V (Table 3). No series resistor is needed for direct connection to standard 5 V CMOS outputs.

Does the device require an input capacitor, and what value is recommended?

Yes-a 100 nF ceramic capacitor placed directly at Pin 1 (I) to Pin 4 (GND) is mandatory for high-frequency stability and line transient suppression. For long supply lines (>1 m), a 470 µF electrolytic capacitor is recommended upstream to buffer low-frequency ripple and load-dump energy, per Figure 3 and application note guidance.
