Product details

Overview

TLE42962GV33HTSA1 from Infineon Technologies is a monolithic low-dropout linear voltage regulator delivering 3.3 V ±4% output at up to 30 mA, with dropout voltage as low as 250 mV at 20 mA, input voltage range of 4.0–45 V, and AEC-Q100 qualification for automotive microcontroller and sensor supply under harsh thermal conditions (T_j = −40°C to +150°C).

For engineers reviewing the TLE42962GV33HTSA1 datasheet, TLE42962GV33HTSA1 pinout, TLE42962GV33HTSA1 application, or TLE42962GV33HTSA1 equivalent, key selection factors include its inhibit-controlled standby mode (<5 µA quiescent current), ceramic-capacitor stability (C_Q ≥3.3 µF, ESR ≤2 Ω), reverse-polarity protection, and integrated short-circuit and overtemperature shutdown.

Technical Context

The device implements a band-gap referenced control loop with saturation-based pass transistor drive, enabling stable regulation across wide input voltage and temperature ranges. Its thermal protection circuit disables the output when junction temperature exceeds safe limits, and the inhibit input directly controls internal biasing to achieve ultra-low standby current.

Designed for automotive environments, it operates with no external compensation required and maintains regulation even during cold-crank (VI down to 4.0 V for 3.3 V version) and load-dump transients (VI up to 45 V). The dual GND pins (pins 2 and 5) provide low-inductance return paths and enhance thermal dissipation in the PG-SCT595-5 package.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	3.3 V ±4% (3.17–3.43 V); maintains accuracy across 1–30 mA load and −40°C to +150°C junction temperature.
Max Output Current	30 mA; current limit triggers when V_Q drops 100 mV below nominal, protecting against sustained overload.
Dropout Voltage	250 mV (typ.) at 20 mA; enables regulation with only 3.55 V input for 3.3 V output - critical for low-voltage battery operation.
Quiescent Current	170 µA (typ.) active; <5 µA in inhibit-off standby - reduces parasitic drain in always-on vehicle modules.
Inhibit Threshold	Turn-on: V_INH ≥2.2 V; turn-off: V_INH ≤0.4 V; compatible with standard CMOS logic without level-shifting.
Input Voltage Range	4.0–45 V; supports 12 V and 24 V automotive systems including cold-crank (4 V) and load-dump (45 V) extremes.
Protection Functions	Short-circuit, overtemperature, reverse-polarity, and ESD (2 kV HBM); eliminates need for external protection components.

Pinout & Package

Package: PG-SCT595-5 - thermally enhanced 5-pin SMD package with exposed thermal pad, optimized for high ambient temperature operation and compact PCB layout in automotive ECUs.

Pin/Terminal	Circuit Role	Design Meaning
1 (INH)	Inhibit input	CMOS-compatible digital enable/disable control; high (>2.2 V) activates regulator, low (<0.4 V) forces <5 µA standby current.
2 (GND)	Ground reference	Primary ground connection; internally tied to pin 5 for low-impedance return and improved thermal conduction.
3 (IN)	Input voltage supply	Accepts 4.0–45 V DC; designed to withstand automotive transients without external TVS or clamping diodes.
4 (OUT)	Regulated output	3.3 V output requiring ≥3.3 µF ceramic capacitor (ESR ≤2 Ω) for stability; drives MCU cores, sensors, or CAN transceivers.
5 (GND)	Secondary ground / thermal pad	Electrically connected to pin 2; serves as main thermal path to PCB copper; must be soldered to large thermal land.

Key Features

Feature	Design Value
AEC-Q100 qualified	Qualified per Grade 1 (−40°C to +125°C ambient) and extended junction range (−40°C to +150°C), enabling use in engine bay and transmission control units.
Ceramic capacitor stability	Stable with C_Q ≥3.3 µF, ESR ≤2 Ω - eliminates need for costly tantalum or aluminum electrolytic capacitors.
Reverse polarity protection	Withstands −42 V input without damage - prevents field failure due to battery misconnection during service.
Thermal shutdown with auto-recovery	Disables output above safe T_j; resumes regulation once cooled - avoids latch-up and enables fault-tolerant operation.
Low-noise power delivery	60 dB PSRR at 100 Hz - suppresses alternator ripple and improves ADC reference stability in sensor interfaces.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV73333PDBVR	300 mA output, 220 mV dropout, but only rated to +125°C junction and not AEC-Q100 qualified.	Suitable for non-safety industrial or consumer applications; lacks reverse-polarity and load-dump robustness.	Select only for cost-sensitive non-automotive designs where full automotive qualification is unnecessary.
TPS7B6733QPWPRQ1	400 mA output, 300 mV dropout, AEC-Q100 Grade 1, but requires minimum 10 µF output capacitance and has higher quiescent current (25 µA typical active).	Better for higher-current loads; less suitable for ultra-low-power wake-up circuits due to higher I_q.	Prefer when >30 mA load current or tighter line regulation (±1%) is required, accepting larger output cap footprint.

Compared with TLV73333PDBVR and TPS7B6733QPWPRQ1, TLE42962GV33HTSA1 uniquely balances ultra-low standby current (<5 µA), AEC-Q100 qualification, reverse-polarity hardening, and minimal 3.3 µF ceramic capacitor requirement - making it optimal for space-constrained, always-on automotive nodes.

FAQ

What is the minimum input voltage required for regulation at 3.3 V output?

The TLE42962GV33HTSA1 maintains regulation down to 4.0 V input across its full operating temperature range. This allows reliable operation during automotive cold-crank events where battery voltage can dip to 4–6 V, ensuring uninterrupted power to safety-critical microcontrollers and sensors without brownout resets.

Can this regulator operate without an output capacitor?

No - the device requires a minimum 3.3 µF ceramic output capacitor with ESR ≤2 Ω at 10 kHz for stability. Omitting or undersizing the capacitor causes oscillation and output voltage instability, especially under dynamic load changes common in microcontroller wake-up sequences.

How does the inhibit function interact with thermal shutdown?

When INH is pulled low, the regulator enters ultra-low-power standby (<5 µA), disabling all internal circuitry including thermal monitoring. Thermal shutdown only activates during normal operation (INH high); the device remains safely off during inhibit, preventing unintended restart after overtemperature events.

Is the PG-SCT595-5 package lead-free and RoHS compliant?

Yes - TLE42962GV33HTSA1 is manufactured in a green, RoHS-compliant PG-SCT595-5 package with lead-free terminations and halogen-free molding compound, meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) and supporting standard reflow profiles.
