Product details
Overview
TL750M10CKCE3 from Texas Instruments is a 10-V, 750-mA low-dropout linear voltage regulator in TO-220 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 standby power systems.
For engineers reviewing the TL750M10CKCE3 datasheet, TL750M10CKCE3 pinout, TL750M10CKCE3 application, or TL750M10CKCE3 equivalent, key selection criteria include dropout performance under 750 mA, reverse-battery tolerance, quiescent current stability across load, and compatibility with 10-μF tantalum output capacitors meeting ESR guidelines.
Technical Context
The TL750M10CKCE3 implements a bandgap-referenced control loop with integrated overvoltage shutdown, thermal foldback, and current-limiting circuitry. Its architecture sustains regulation down to 0.6 V headroom and withstands transient 60-V load dumps without external clamping.
It operates across 0°C to 125°C virtual junction temperature and requires a minimum 10-μF tantalum output capacitor with ESR between 0.13 Ω and 2 Ω for stability-ESR range depends on load current and capacitance value per TI Figure 1 and Figure 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 10 V ±1% (9.9–10.1 V at 25°C; 9.8–10.2 V over 0°C–125°C) |
| Max Output Current | 750 mA continuous-supports high-current microcontroller rails or sensor subsystems without derating at TJ ≤ 125°C |
| Dropout Voltage | 0.6 V at 750 mA-enables operation with input as low as 11 V while maintaining 10 V output |
| Load-Dump Protection | Withstands 60-V transients (t ≥ 5 ms)-eliminates need for external TVS in 12-V automotive battery systems |
| Quiescent Current | 60–75 mA at 750 mA load-minimizes standby power loss in always-on modules |
| Input Voltage Range | 11–26 V continuous-covers cold-crank (≥11 V) to alternator surge (≤26 V) in automotive applications |
| Ripple Rejection | 50–55 dB at 120 Hz-suppresses alternator ripple without additional filtering stages |
Pinout & Package
TL750M10CKCE3 uses the TO-220 (KCS) package with 3 leads: Input (Pin 1), Ground/Common (Pin 2), Output (Pin 3). The mounting base is electrically connected to Pin 2 (Common), enabling direct heatsinking to chassis ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | INPUT | Unregulated positive supply input-must be ≥11 V and ≤26 V; connects to battery or DC source |
| Pin 2 | COMMON | Ground reference and thermal tab connection-requires low-impedance PCB copper pour for thermal management |
| Pin 3 | OUTPUT | Regulated 10-V output-drives downstream logic, sensors, or analog circuitry with <100 mV load regulation error |
Key Features
| Feature | Design Value |
|---|---|
| Very low dropout | ≤0.6 V at 750 mA enables use in low-headroom battery systems where input may dip near output voltage |
| 60-V load-dump protection | Integrated clamp eliminates need for external 60-V TVS diode in automotive front-end power supplies |
| Reverse-battery protection | Withstands –50 V transient (100 ms) and –15 V continuous-prevents damage during battery installation errors |
| Thermal overload shutdown | Automatic foldback limits junction temperature to ≤150°C-protects against sustained overload or poor heatsinking |
| Low quiescent current | 5 mA at 10 mA load and 60–75 mA at full 750 mA-reduces parasitic drain in always-on vehicle modules |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC I/O Power Rail |
|---|---|
Use Scenario: Powers microcontroller, CAN transceiver, and door-lock actuators from 12-V battery with cold-crank resilience. IC Role / Device Role / Timing Role: Primary 10-V LDO supplying regulated rail to safety-critical sub-systems. Use Value: 60-V load-dump immunity prevents field failures during alternator transients; 0.6-V dropout maintains regulation during 9-V cold-crank events. |
Use Scenario: Provides stable 10-V supply to isolated analog input channels and digital I/O drivers in factory-floor controllers. IC Role / Device Role / Timing Role: Local point-of-load regulator decoupling main 24-V DC bus. Use Value: Internal overcurrent limiting protects against shorted sensor wiring; thermal shutdown avoids latch-up during ambient >85°C operation. |
| Telematics GPS/Cellular Module | Medical Portable Diagnostic Device |
Use Scenario: Supplies 10-V rail to GNSS receiver and LTE modem in vehicle-mounted telematics units. IC Role / Device Role / Timing Role: Low-noise, low-quiescent LDO ensuring clean power for RF-sensitive receivers. Use Value: 50–55 dB ripple rejection suppresses alternator noise; 1000 μV output noise (10 Hz–100 kHz) avoids RF desense. |
Use Scenario: Powers ADC reference, op-amps, and display controller in battery-operated ultrasound or glucose meters. IC Role / Device Role / Timing Role: Precision voltage source delivering stable 10 V for analog signal chain biasing. Use Value: Tight 1% output tolerance (±0.1 V) ensures measurement accuracy; low dropout extends usable battery life by >15% vs. standard regulators. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL750M10CKCS | Same electrical specs and TO-220 package; RoHS-compliant Pb-free finish (CU SN) vs. legacy SnPb of TL750M10CKCE3 | Required for new designs targeting RoHS compliance; identical thermal and electrical behavior | Select TL750M10CKCS for production builds requiring lead-free assembly and active TI support. |
| TL750M10CKVURG3 | PowerFLEX™ KVU package (3-pin flange-mount); same 10-V/750-mA specs but lower θJA = 28°C/W vs. TO-220's 22°C/W | Better thermal performance in space-constrained enclosures; requires different PCB footprint and mounting hardware | Choose TL750M10CKVURG3 when board area is limited and thermal resistance must be minimized without external heatsink. |
Compared with TL750M10CKCE3, TL750M10CKCS offers identical performance with modern RoHS compliance, while TL750M10CKVURG3 trades TO-220 mechanical compatibility for superior thermal dissipation in compact industrial modules-neither is pin-compatible due to differing package footprints and thermal tab configurations.

FAQ
What is the maximum input voltage rating for TL750M10CKCE3?
The TL750M10CKCE3 supports 26 V continuous input voltage and withstands 60 V transient input (t ≥ 5 ms) per its absolute maximum ratings. This 60-V load-dump capability is built-in and does not require external protection components-making TL750M10CKCE3 suitable for direct connection to automotive 12-V battery rails.
Does TL750M10CKCE3 require an output capacitor, and what type is recommended?
Yes, TL750M10CKCE3 requires a minimum 10-μF tantalum output capacitor with ESR between 0.13 Ω and 2 Ω for stable operation. TI specifies this range in Figure 1 of the datasheet and warns that values outside it risk oscillation-electrolytic or ceramic alternatives are not recommended unless ESR is actively compensated per Table 1.
Is TL750M10CKCE3 pin-compatible with other TL750M variants like TL750M05 or TL750M12?
Yes, all TL750Mxx devices-including TL750M10CKCE3-share identical TO-220 (KCS) pinout: Pin 1 = INPUT, Pin 2 = COMMON, Pin 3 = OUTPUT. Voltage variants differ only in internal feedback network; thus TL750M10CKCE3 can replace TL750M05CKCS or TL750M12CKCS in same footprint if system voltage requirements align.
What thermal considerations apply to TL750M10CKCE3 in continuous 750-mA operation?
At 750 mA and 26-V input, TL750M10CKCE3 dissipates up to 12 W. With θJA = 22°C/W (TO-220), junction temperature rise exceeds safe limits without heatsinking. TI recommends using the metal tab (Pin 2) as thermal path to chassis ground-derating is required above 75°C ambient unless a heatsink lowers effective θJA below 10°C/W.
How does TL750M10CKCE3 handle reverse-battery conditions?
TL750M10CKCE3 tolerates –15 V continuous reverse input and –50 V transient (100 ms), protecting downstream circuitry during incorrect battery installation. This reverse-polarity immunity is implemented via internal protection diodes-no external series diode is needed, preserving efficiency and dropout performance.
