Product details
Overview
TLE4299GMV33 from Infineon is a monolithic low-dropout linear voltage regulator delivering a fixed 3.3 V ±2% output with up to 150 mA load current, featuring integrated inhibit control (INH), reset output (RO), sense input (SI), and early warning functionality - designed for continuous microcontroller power supply in automotive stop-start systems.
For engineers reviewing the TLE4299GMV33 datasheet, TLE4299GMV33 pinout, TLE4299GMV33 application, or TLE4299GMV33 equivalent, key selection criteria include its 4.4–45 V input range, <1 µA off-state quiescent current, reset delay programmability via external capacitor, adjustable reset threshold, and AEC-Q100 qualification for under-hood environments.
Technical Context
The TLE4299GMV33 uses a PNP-based regulation architecture enabling ultra-low dropout operation down to VI = 1 V while maintaining 3.3 V output stability. Its internal bandgap reference and current-saturation control ensure ±2% output tolerance across -40°C to +150°C junction temperature.
It integrates three supervisory functions: (1) reset generation with externally adjustable delay and threshold via RADJ and D pins; (2) early warning via SI/SO with hysteresis; and (3) inhibit-controlled shutdown reducing IQ to <1 µA. All protections - overtemperature, short-circuit, reverse polarity - are implemented on-die without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V ±2% - maintains stable MCU core/logic rail despite battery transients and load steps. |
| Max Output Current | 150 mA - sufficient for typical automotive microcontrollers and peripheral ICs. |
| Input Voltage Range | 4.4 V to 45 V - supports 12 V and 24 V automotive systems including cold-crank (4.4 V) and load-dump (45 V). |
| Quiescent Current (ON) | Typ. 100 µA - enables always-on ECU subsystems without excessive standby drain. |
| Off-State Current (INH) | <1 µA - meets automotive "sleep mode" current budgets for extended parking scenarios. |
| Reset Threshold Range | Adjustable from 2.2 V to 3.1 V via RADJ resistor divider - allows precise match to MCU reset requirements. |
| Operating Junction Temp | -40°C to +150°C - qualified per AEC-Q100 Grade 0 for under-hood placement. |
Pinout & Package
Package: PG-DSO-14 (14-pin exposed pad SOIC variant, RoHS-compliant, thermally enhanced for automotive ambient conditions).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 RADJ | Reset threshold adjust input | Resistor divider node setting reset activation voltage; connects to GND if unused. |
| 2 D | Reset delay capacitor connection | External capacitor to GND sets reset assertion/deassertion timing; critical for glitch immunity. |
| 3,4,5 & 10,11,12 GND | Ground terminals | Multiple low-inductance ground paths improve noise immunity and thermal dissipation. |
| 6 INH | Inhibit control input | Active-high logic signal; high = regulator enabled, low = shutdown (<1 µA IQ). |
| 7 RO | Open-collector reset output | Pulled high internally via 20 kΩ; asserts low during reset; compatible with 3.3 V/5 V MCUs. |
| 8 SO | Open-collector sense output | Signals early warning of input/sense voltage drop; requires external pull-up. |
| 9 Q | Regulated 3.3 V output | Requires 22 µF output capacitor with 0.4–3.7 Ω ESR for stability and transient response. |
| 13 I | Main input voltage | Connect ceramic bypass capacitor directly at pin for high-frequency noise suppression. |
| 14 SI | Sense input | Monitors external voltage (e.g., battery); connects to Q if unused. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated inhibit function | ENables zero-power shutdown mode (<1 µA IQ) for ECU sleep states without external FET or controller. |
| Programmable reset delay | Delay time set by single external capacitor on D pin - eliminates need for discrete RC timing networks. |
| Adjustable reset threshold | Voltage threshold set via resistor divider on RADJ - supports diverse MCU reset specifications. |
| Early warning supervision | SO pin asserts before reset occurs, giving µC time to save state or initiate controlled shutdown. |
| AEC-Q100 Grade 0 qualification | Validated for -40°C to +150°C operation with full electrical characterization - no derating required. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70733PDBVR | 300 mA output, 2.5 µA IQ (ON), no inhibit or reset features, SOT-23-5 package | Lacks integrated reset, early warning, and inhibit - requires external supervisor IC and enable logic | Preferred only for cost-sensitive non-automotive designs where full supervision is handled elsewhere |
| TLE42744G | 45 V input, 400 mA output, fixed 5 V output, includes reset but no inhibit or SI/SO | Higher current, 5 V output - incompatible for 3.3 V logic rails without additional regulation | Only suitable when system requires 5 V MCU core voltage and reset-only supervision |
Compared with TLV70733PDBVR and TLE42744G, the TLE4299GMV33 uniquely combines 3.3 V regulation, inhibit control, programmable reset, and early warning in a single AEC-Q100-qualified device - reducing BOM count and PCB area in safety-critical automotive domains.

FAQ
What is the minimum input voltage required for regulation?
The TLE4299GMV33 maintains regulation down to an input voltage of 4.4 V under nominal load and full temperature range. Below this, output voltage drops linearly with input; however, the reset function remains active down to VI = 1 V to ensure controlled MCU shutdown even during deep battery discharge.
How is the reset delay time calculated?
Reset delay time tD is determined by the external capacitor CD connected between pin D and GND: tD ≈ CD × 1.2 µs/pF. For example, a 100 nF capacitor yields ~120 ms delay. This timing governs both reset assertion after undervoltage and deassertion after recovery, as defined in Infineon's Application Note AN2017-05.
Can the SI pin monitor voltages other than the input supply?
Yes - the SI pin is a high-impedance sense input that can monitor any DC voltage within -0.3 V to 45 V. It is commonly used to supervise battery voltage, auxiliary rails, or sensor supply lines. The early warning threshold is set independently via external resistors RSI1/RSI2, decoupled from the main regulator output.
Is the PG-DSO-14 package thermally compatible with standard reflow profiles?
Yes - the PG-DSO-14 package is qualified for lead-free reflow per JEDEC J-STD-020 Rev. E, with peak temperature up to 260°C. Its exposed thermal pad must be soldered to a minimum 300 mm² copper pour for optimal thermal performance, achieving Rthja = 70 K/W under recommended layout conditions.
