Product details
Overview
TL750M12CKCE3 from Texas Instruments is a 12-V, 750-mA low-dropout linear voltage regulator in TO-220 package with integrated overvoltage, thermal, and current-limiting protection. It delivers ≤0.6 V dropout at full load, supports 13–26 V input range, and operates from 0°C to 125°C virtual junction temperature - ideal for automotive battery-powered standby systems requiring robust load-dump (60 V) and reverse-battery tolerance.
For engineers reviewing the TL750M12CKCE3 datasheet, TL750M12CKCE3 pinout, TL750M12CKCE3 application, or TL750M12CKCE3 equivalent, key selection considerations include dropout voltage under 750 mA load, 60-V transient input survival, quiescent current stability across output current, and compatibility with 10-μF tantalum output capacitors meeting ESR guidelines.
Technical Context
The TL750M12CKCE3 uses bandgap-referenced error amplification with internal current limiting and thermal shutdown circuitry. Its protection architecture includes dedicated overvoltage detection that triggers shutdown during 60-V load-dump transients and reverse-battery conditions down to –50 V for 100 ms.
Stability relies on external output capacitor ESR between 0.13 Ω and 2 Ω (for 10–400 μF), with minimum recommended capacitance of 10 μF tantalum. Input regulation is specified at ±12 mV over 13–26 V input range at 250 mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 12 V ±1% (11.76–12.24 V over 0°C–125°C TJ) |
| Max Output Current | 750 mA continuous - supports high-current microcontroller or sensor rails without external pass devices |
| Dropout Voltage | 0.6 V at 750 mA - enables operation with only 13 V input for stable 12 V output |
| Input Voltage Range | 13–26 V continuous; survives 60 V transient (load-dump) and –50 V reverse-battery pulses |
| Quiescent Current | 60–75 mA at 750 mA load - maintains low power loss in always-on automotive modules |
| Ripple Rejection | 50–55 dB at 120 Hz - suppresses alternator ripple in vehicle electrical systems |
| Thermal Protection | Internal thermal overload shutdown - prevents damage during sustained overload or poor heatsinking |
Pinout & Package
TL750M12CKCE3 uses TO-220 package (KCS drawing), with metal tab electrically connected to COMMON pin. The common terminal is in direct electrical contact with the mounting base for thermal and ground path integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INPUT | Regulator input supply connection | Accepts 13–26 V DC; must withstand 60 V transients per ISO 7637-2 pulse 5a |
| COMMON | Ground reference and thermal tab connection | Electrically tied to mounting base; requires low-impedance PCB thermal pad for >1 W dissipation |
| OUTPUT | Regulated 12 V output | Delivers up to 750 mA with ≤120 mV load regulation error across full current range |
Key Features
| Feature | Design Value |
|---|---|
| 60-V Load-Dump Protection | Survives automotive ISO 7637-2 Pulse 5a without external clamping - eliminates need for TVS diode |
| Reverse-Battery Tolerance | Withstands –50 V for 100 ms - protects against jump-start polarity reversal in 12 V systems |
| Low Dropout Architecture | 0.6 V dropout at 750 mA enables use in degraded battery conditions (e.g., 12.6 V cranking) |
| Integrated Thermal Shutdown | Auto-recovery after cooldown - prevents latch-up during thermal overload in enclosed enclosures |
| Current-Limiting Circuitry | Internal foldback limit protects against short-circuit faults without external sense resistors |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout voltage regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL750M12CKCSE3 | Same electrical specs; Pb-Free (RoHS) finish; active status vs. TL750M12CKCE3's obsolete status | Identical pinout and thermal performance; preferred for new designs requiring RoHS compliance | Select TL750M12CKCSE3 for production builds - TL750M12CKCE3 is obsolete and no longer manufactured |
| TL750M12CKVURG3 | PowerFLEX™ KVU package (surface-mount); same 12 V/750 mA specs; 28°C/W θJA vs. 22°C/W for TO-220 | Better suited for automated assembly and compact layouts; requires reflow-compatible PCB layout | Choose TL750M12CKVURG3 when SMT placement, smaller footprint, or higher-volume manufacturing is required |
Compared with TL750M12CKCE3, TL750M12CKCSE3 offers identical performance with RoHS compliance and active status, while TL750M12CKVURG3 provides surface-mount flexibility at the cost of slightly reduced thermal efficiency - both require no schematic changes but differ in assembly process and thermal management strategy.

FAQ
What is the maximum input voltage TL750M12CKCE3 can withstand without damage?
The TL750M12CKCE3 supports 26 V continuous input voltage and is rated to survive 60 V transient input (e.g., ISO 7637-2 Pulse 5a load-dump events) without failure. This 60-V rating is validated per TI's absolute maximum ratings and functional block diagram protection architecture - critical for automotive 12 V systems where alternator surges occur.
Does TL750M12CKCE3 require an external capacitor on the output, and what are the requirements?
Yes, TL750M12CKCE3 requires a minimum 10-μF tantalum output capacitor with ESR between 0.13 Ω and 2 Ω for stable operation. The datasheet specifies this range based on load current and temperature; using ceramic capacitors without series resistance may cause instability due to insufficient ESR.
Is TL750M12CKCE3 pin-compatible with other regulators in the TL750M family?
Yes, all TL750Mxx variants including TL750M12CKCE3 share identical TO-220 (KCS) pinout: INPUT, COMMON, OUTPUT in that order. This allows direct substitution between 5 V, 8 V, 10 V, and 12 V versions without PCB modification - provided input/output voltage margins and thermal design accommodate the specific variant.
What protection features are built into TL750M12CKCE3?
TL750M12CKCE3 integrates four protection functions: (1) overvoltage shutdown for 60-V transients, (2) internal thermal overload shutdown, (3) current-limiting circuitry with foldback behavior, and (4) reverse-battery tolerance to –50 V for 100 ms - all implemented on-die without external components.
Why is TL750M12CKCE3 marked as OBSOLETE, and what is the recommended replacement?
TL750M12CKCE3 is obsolete per TI's Package Option Addendum (2010), with TL750M12CKCSE3 designated as the active, Pb-Free (RoHS) replacement. Both share identical electrical specs and TO-220 package; TL750M12CKCSE3 is recommended for all new designs and volume production due to ongoing manufacturability and compliance support.
