Product details
Overview
TL750M05CKCSE3 from Texas Instruments is a 5-V, 750-mA low-dropout linear voltage regulator in TO-220 (KCS) package, featuring dropout voltage <0.6 V at full load, 60-V load-dump protection, and internal thermal/overcurrent limiting-designed for battery-powered automotive and industrial systems requiring stable 5-V rail under transient stress.
For engineers reviewing the TL750M05CKCSE3 datasheet, TL750M05CKCSE3 pinout, TL750M05CKCSE3 application, or TL750M05CKCSE3 equivalent, key selection criteria include dropout performance at 750 mA, load-dump immunity up to 60 V, quiescent current behavior across load range, and thermal resistance (θJA = 28.7°C/W) in TO-220 mounting configurations.
Technical Context
The TL750M05CKCSE3 implements a bandgap-referenced control loop with integrated overvoltage shutdown and current-limiting circuitry. Its architecture supports operation with input voltages from 6 V to 26 V while maintaining regulated 5-V output across 0–750 mA load and 0°C to 125°C virtual junction temperature.
Protection features are hardware-based: reverse-battery tolerance to –50 V (100 ms), 60-V transient input survival, and thermal shutdown activation before junction exceeds 150°C. Output stability requires external 10-µF tantalum capacitor with ESR between 0.13 Ω and 2 Ω depending on load current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±1% (4.95–5.05 V at 25°C; 4.9–5.1 V over 0–125°C) |
| Max Output Current | 750 mA continuous-supports high-current microcontroller rails or sensor subsystems without external pass devices |
| Dropout Voltage | 0.6 V at 750 mA-enables regulation from 5.6-V input, critical for single-cell LiFePO₄ or degraded lead-acid battery operation |
| Input Voltage Range | 6 V to 26 V continuous; survives 60-V transients-meets ISO 7637-2 Pulse 5a load-dump requirement |
| Quiescent Current | 5 mA at 10 mA load; 75 mA at 750 mA load-minimizes standby power loss in always-on vehicle modules |
| Ripple Rejection | 50–55 dB at 120 Hz-suppresses alternator ripple in automotive 12-V systems |
| Thermal Resistance | θJA = 28.7°C/W (TO-220 KCS)-requires ≥2.5 cm² copper pour for full-load operation at 125°C ambient |
Pinout & Package
TL750M05CKCSE3 uses the TO-220 (KCS) package with 3 pins and exposed metal tab electrically connected to COMMON (GND). Mounting base contact enables direct thermal coupling to heatsink or PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INPUT) | Regulator input | Accepts 6–26 V DC; must be decoupled with 0.1-µF ceramic capacitor close to pin |
| 2 (COMMON) | Ground reference & thermal path | Electrically tied to mounting base; requires low-impedance connection to system GND and thermal mass |
| 3 (OUTPUT) | Regulated 5-V output | Supplies load; requires 10-µF tantalum capacitor with controlled ESR (0.13–2 Ω) for stability |
Key Features
| Feature | Design Value |
|---|---|
| 60-V Load-Dump Protection | Withstands ISO 7637-2 Pulse 5a transients without external TVS-reduces BOM count in automotive ECUs |
| Reverse-Battery Tolerance | Survives –50 V for 100 ms-eliminates need for series diode in battery-connected applications |
| Low Quiescent Current | 5 mA at light load-extends battery life in always-on telematics or alarm modules |
| Integrated Thermal Shutdown | Activates before virtual junction reaches 150°C-prevents permanent damage during overload or poor heatsinking |
| Overcurrent Limiting | Hardware-limited foldback current-protects against short-circuit without latch-up or external sensing |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC I/O Power Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1117-50CDCYR | Lower max current (800 mA vs 750 mA); higher dropout (1.2 V at 800 mA); no load-dump protection | Suitable for non-automotive consumer electronics; lacks 60-V transient rating | Select when cost sensitivity outweighs automotive robustness requirements |
| LM2940CT-5.0/NOPB | Higher dropout (0.9 V at 500 mA); same 60-V load-dump rating; higher quiescent current (10 mA) | Compatible with legacy designs using LM2940 footprint; wider input range (up to 26 V) | Choose for drop-in replacement in existing LM2940-based boards needing identical pinout |
Compared with TLV1117-50CDCYR and LM2940CT-5.0/NOPB, TL750M05CKCSE3 delivers superior dropout performance at full load and lower quiescent current under light loads-making it optimal for battery-constrained automotive modules where thermal margin and transient resilience are critical.

FAQ
What is the maximum input voltage TL750M05CKCSE3 can withstand without damage?
TL750M05CKCSE3 supports continuous input voltage up to 26 V and survives transient input voltages up to 60 V per ISO 7637-2 Pulse 5a. This 60-V rating applies for defined pulse durations and is validated per TI's production test flow-not a derated specification. The device remains functional after such events if thermal limits are not exceeded during recovery.
Does TL750M05CKCSE3 require an external capacitor on the output, and what are the ESR constraints?
Yes, TL750M05CKCSE3 requires a 10-µF tantalum capacitor on the output for stability, with equivalent series resistance (ESR) between 0.13 Ω and 2 Ω depending on load current. At 200 mA load, minimum ESR is 0.8 Ω; at lighter loads, ESR must increase toward 2 Ω. Using ceramic capacitors without series resistance risks instability and oscillation.
How does the thermal performance of TL750M05CKCSE3 compare across its available packages?
TL750M05CKCSE3 in TO-220 (KCS) has θJA = 28.7°C/W, while the KTT (TO-263) variant measures 27.5°C/W and KVU (TO-252) is 50.9°C/W. The KCS package offers the best junction-to-ambient thermal resistance among variants, making it preferred for high-power-density designs where heatsinking is constrained.
Is TL750M05CKCSE3 qualified for automotive applications per AEC-Q100?
No-TL750M05CKCSE3 is not AEC-Q100 qualified. For automotive applications requiring Q100 compliance, TI offers the TL750M-Q1 variant, which undergoes additional stress testing and screening. TL750M05CKCSE3 meets industrial temperature range (0°C to 125°C) but lacks the zero-defect reliability validation required for safety-critical vehicle systems.
Can TL750M05CKCSE3 be used in reverse-battery configurations?
Yes-TL750M05CKCSE3 tolerates –50 V reverse input voltage for 100 ms and –15 V continuously, eliminating the need for external series diodes in battery-connected circuits. This capability is implemented via internal protection circuitry and verified across production lots per TI's qualification standards.
