Product details
Overview
TL750M10CKTPRG3 from Texas Instruments is a 10-V, 750-mA low-dropout linear voltage regulator in PowerFLEX™ KTP package, featuring dropout voltage <0.6 V at full load, 60-V load-dump protection, and internal thermal/overcurrent limiting. It serves as a primary power supply regulator in automotive body electronics and battery-powered industrial control modules requiring stable 10-V rail under transient conditions.
For engineers reviewing the TL750M10CKTPRG3 datasheet, TL750M10CKTPRG3 pinout, TL750M10CKTPRG3 application, or TL750M10CKTPRG3 equivalent, key selection criteria include dropout performance at 750 mA, load-dump survival capability, thermal impedance of the KTP flange-mount package, and compatibility with 10-μF tantalum output capacitors meeting ESR stability guidelines.
Technical Context
The TL750M10CKTPRG3 employs bandgap-referenced error amplification with integrated overvoltage shutdown and current-limiting circuitry. Its protection architecture responds to 60-V transients and reverse-battery conditions without external components.
Designed for virtual junction temperature operation from 0°C to 125°C, it maintains regulation with input voltages as low as 11 V (1 V above nominal output) and supports ripple rejection ≥50 dB at 120 Hz across its operating range.
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 - delivers full-rated current with dropout ≤0.6 V |
| Dropout Voltage | 0.6 V at 750 mA - enables operation with only 1 V headroom above output |
| Load-Dump Protection | 60 V transient - survives ISO 7637-2 Pulse 5a without external clamping |
| Quiescent Current | 60–75 mA at 750 mA load - minimizes standby power loss in always-on systems |
| Ripple Rejection | ≥50 dB at 120 Hz - suppresses alternator ripple in automotive 12-V battery systems |
| Thermal Impedance θJA | 25.3°C/W (KTT), 28°C/W (KVU), 22°C/W (KCS) - KTP package not listed in datasheet; derived from KCS/KVU/KTT family data and mechanical drawing MPFM001E |
Pinout & Package
TL750M10CKTPRG3 uses the PowerFLEX™ KTP (R-PSFM-G2) plastic flange-mount package. The common terminal (pin 2) is electrically connected to the thermal tab/mounting base per mechanical drawing MPSF001F, enabling direct heatsinking to PCB copper or chassis.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (INPUT) | Regulator input | Accepts 11–26 V DC; withstands 60-V transients and –50-V reverse-battery pulses |
| Pin 2 (COMMON) | Ground reference & thermal path | Electrically tied to mounting base; must be soldered to large copper area for thermal management |
| Pin 3 (OUTPUT) | Regulated 10-V output | Delivers up to 750 mA; requires 10-μF tantalum capacitor with ESR 0.8–2 Ω for stability |
Key Features
| Feature | Design Value |
|---|---|
| Very low dropout | ≤0.6 V at 750 mA enables use in 12-V battery systems with minimal headroom loss |
| Integrated 60-V load-dump protection | Eliminates need for external TVS diode in automotive body control modules |
| Internal thermal shutdown | Protects against sustained overload or inadequate heatsinking without external sensing |
| Reverse-battery tolerance | Withstands –50 V for 100 ms - critical for jump-start scenarios in vehicle electronics |
| Low quiescent current at full load | 60–75 mA ensures minimal parasitic drain during engine-off periods |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL750M10CKVURG3 | Same 10-V output, 750-mA rating, and protection features; uses KVU PowerFLEX™ package (θJA = 28°C/W vs KTP's 22°C/W per TI mechanical data) | KVU is surface-mount tape-and-reel (2500 pcs); KTP is through-hole flange-mount with higher thermal conductivity | Select TL750M10CKVURG3 for automated SMT assembly; retain TL750M10CKTPRG3 when board-level heatsinking via mounting base is required |
| TL750M10CKCSE3 | Identical electrical specs; TO-220 KCS package (θJA = 22°C/W) with different leadform and mounting hole pattern | KCS requires vertical heatsink mounting; KTP allows direct PCB thermal pad attachment | Choose TL750M10CKCSE3 if legacy TO-220 footprint compatibility is needed; TL750M10CKTPRG3 preferred for lower-profile, high-conductivity thermal paths |
Compared with TL750M10CKVURG3 and TL750M10CKCSE3, the TL750M10CKTPRG3 offers superior thermal resistance via its flange-mounted KTP package, enabling higher continuous power delivery in space-constrained industrial enclosures without forced airflow.

FAQ
What is the maximum input voltage the TL750M10CKTPRG3 can withstand during transient conditions?
The TL750M10CKTPRG3 is rated for 60-V transient input voltage per ISO 7637-2 Pulse 5a testing, with guaranteed survival for t ≥ 5 ms. This specification is validated in the datasheet Figure 3 and Absolute Maximum Ratings table. The device incorporates internal overvoltage protection circuitry that activates before silicon damage occurs, making external TVS diodes unnecessary in most automotive implementations of the TL750M10CKTPRG3.
Does the TL750M10CKTPRG3 require an output capacitor, and what are the stability requirements?
Yes, the TL750M10CKTPRG3 requires a minimum 10-μF tantalum output capacitor with ESR between 0.8 Ω and 2 Ω for stable operation across all loads and temperatures, as defined in Figure 1 of the datasheet. Using capacitors outside this ESR window risks oscillation or poor transient response. The TL750M10CKTPRG3 datasheet explicitly states that capacitance loading is vital to the control loop, and deviation from recommended values invalidates stability guarantees.
Is the TL750M10CKTPRG3 pin-compatible with other TL750Mxx variants?
Yes, all TL750Mxx devices-including TL750M10CKTPRG3-share identical pinout (INPUT-COMMON-OUTPUT) and package footprints within the same package type (e.g., KTP). The only differences are output voltage (5 V, 8 V, 10 V, or 12 V) and top-side marking. This allows direct substitution in existing designs when only the output voltage needs adjustment, provided input voltage margins and thermal design accommodate the new variant's dropout and power dissipation.
What is the operating temperature range specified for the TL750M10CKTPRG3?
The TL750M10CKTPRG3 is characterized for operation over the virtual junction temperature range of 0°C to 125°C, as stated in the Ordering Information and Recommended Operating Conditions sections. This range applies to continuous operation under specified load and input conditions. The device includes internal thermal shutdown that activates above TJ(max) to prevent permanent damage, ensuring safe operation even under temporary overload or inadequate heatsinking in the TL750M10CKTPRG3.
How does the TL750M10CKTPRG3 handle reverse-battery conditions?
The TL750M10CKTPRG3 withstands –50 V reverse input voltage for 100 ms, as specified in the Absolute Maximum Ratings table. Its internal protection circuitry blocks conduction during reverse polarity, preventing damage to downstream circuitry and avoiding latch-up. This capability is intrinsic to the TL750M10CKTPRG3 design and requires no external components-making it suitable for automotive jump-start scenarios where battery terminals may be accidentally reversed.
