Product details

Overview

TLE4295GV26HTMA1 from Infineon is a monolithic low-dropout linear voltage regulator in PG-SCT595-5 package, designed to supply microcontroller systems in automotive environments. It delivers 3.0 V output at ±4% tolerance, supports 30 mA load current, features power-fail detection (open-collector PF pin), operates from 4.5 V to 45 V input, and includes reverse-polarity protection, short-circuit protection, and thermal shutdown.

For engineers reviewing the TLE4295GV26HTMA1 datasheet, TLE4295GV26HTMA1 pinout, TLE4295GV26HTMA1 application, or TLE4295GV26HTMA1 equivalent, key selection criteria include dropout voltage ≤0.4 V at 20 mA, quiescent current ≤4 mA under full load, AEC-Q100 qualification, -40°C to +150°C junction temperature range, and integrated power-fail signaling for system-level fault monitoring.

Technical Context

The TLE4295GV26HTMA1 implements a bandgap-referenced control loop with saturation detection and thermal foldback, enabling stable regulation under wide input transients and load steps. Its internal PF comparator monitors output voltage collapse and drives an open-collector output that sinks ≥500 µA when V_Q drops below threshold.

Protection logic integrates reverse-polarity blocking, current-limiting (30 mA typical), and thermal shutdown with automatic recovery. The regulator maintains regulation down to V_I = V_Q,nom + 0.5 V, with dropout voltage specified at 0.25 V (typ) / 0.40 V (max) at 20 mA load.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	3.0 V ±4% - Ensures stable MCU core/peripheral supply within automotive-grade accuracy.
Max Output Current	30 mA - Sufficient for low-power sensors, CAN transceivers, or logic-level biasing.
Dropout Voltage	0.25 V (typ), 0.40 V (max) at 20 mA - Enables operation with minimal headroom, e.g., from 3.5 V battery during cranking.
Quiescent Current	≤4 mA at full load; ≤200 µA at light load - Minimizes standby power loss in always-on vehicle modules.
Input Voltage Range	4.5 V to 45 V - Withstands load-dump pulses up to 40 V and cold-crank dips to 4.5 V.
Operating Temperature	-40°C to +150°C (T_j) - Qualified per AEC-Q100 Grade 0 for under-hood placement.
Power Fail Output	Open-collector PF pin pulled low on undervoltage/saturation - Provides direct interface to MCU interrupt or reset controller.

Pinout & Package

Package: PG-SCT595-5 - 5-pin ultra-compact surface-mount package (2.9 mm × 1.6 mm × 0.75 mm), optimized for high-density automotive PCBs with exposed thermal pad (pin 5).

Pin/Terminal	Circuit Role	Design Meaning
1 (PF)	Power fail indicator	Open-collector output pulled low during undervoltage, overload, or output transistor saturation - requires external pull-up for MCU interrupt signaling.
2 (GND)	Ground reference	Primary ground connection; internally bonded to pin 5 for low-inductance thermal path.
3 (I)	Input voltage supply	Accepts 4.5–45 V DC; must be decoupled with ≥10 µF ceramic capacitor near pin.
4 (Q)	Regulated output	3.0 V output; requires ≥2.2 µF tantalum capacitor (ESR ≤5 Ω) for stability and transient response.
5 (GND)	Thermal ground / secondary GND	Exposed thermal pad; must be soldered to PCB copper pour for R_thJSP = 30 K/W thermal performance.

Key Features

Feature	Design Value
AEC-Q100 qualified	Grade 0 (−40°C to +150°C T_j) - Validated for safety-critical automotive ECUs without derating.
Reverse polarity protection	Withstands −42 V input - Eliminates need for external series diode in battery-connected applications.
Integrated short-circuit protection	Current-limited to 30 mA with auto-recovery - Prevents latch-up during wiring faults or ESD events.
Low-dropout architecture	V_dr ≤ 0.4 V at 20 mA - Enables use with degraded 12 V systems (e.g., 6.5 V cranking minimum).
Power fail signaling	Dedicated open-collector PF pin - Provides deterministic early-warning signal before output collapse, enabling graceful MCU shutdown.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV73330PDBVR	300 mA output, 250 mV dropout, no PF pin, not AEC-Q100 qualified	Suitable for non-automotive industrial MCU rails; lacks fault signaling and automotive qualification	Select only for cost-sensitive non-automotive designs requiring higher current.
NCP1117ST33T3G	800 mA output, 1.2 V dropout, no PF pin, AEC-Q100 Grade 3 (−40°C to +125°C)	Higher current but wider dropout and lower temp rating; no power-fail alert capability	Prefer where load exceeds 30 mA and PF signaling is unnecessary; verify thermal margin at 125°C max.

Compared with TLV73330PDBVR and NCP1117ST33T3G, the TLE4295GV26HTMA1 uniquely combines AEC-Q100 Grade 0 qualification, integrated PF signaling, reverse-polarity immunity, and sub-0.4 V dropout in a 5-pin automotive package-making it irreplaceable for safety-critical, space-constrained, fault-aware 3.0 V regulation.

FAQ

What is the function of the PF pin on TLE4295GV26HTMA1?

The PF (Power Fail) pin is an open-collector output that pulls low when the output voltage collapses due to input undervoltage, output overload, or internal saturation. It requires an external pull-up resistor (typically 10 kΩ to V_CC) and directly interfaces with MCU interrupt or reset inputs to enable controlled shutdown before brownout occurs.

Can TLE4295GV26HTMA1 operate with a 5 V input supply?

Yes - the device operates from 4.5 V to 45 V input. At 5 V input, dropout is ~0.25 V (typ), delivering regulated 3.0 V output with ≥2.5 V headroom. This enables reliable operation during cold-crank conditions where battery voltage may dip to 4.5 V while maintaining full 30 mA output capability.

Is an external capacitor required on the Q pin, and what type is recommended?

Yes - a minimum 2.2 µF tantalum capacitor with ESR ≤5 Ω at 10 kHz is mandatory on the Q (output) pin for stability and transient response. Ceramic capacitors are not recommended alone due to insufficient ESR; if used, add a 1 Ω series resistor to meet ESR requirement and prevent oscillation.

How does reverse polarity protection work in TLE4295GV26HTMA1?

The device incorporates internal reverse-battery protection circuitry that blocks conduction when input polarity is inverted. It withstands −42 V applied to the I pin without damage or excessive current draw, eliminating the need for an external series diode and reducing BOM count and power loss in battery-connected automotive modules.
