Product details
Overview
TL750M08CKTPRG3 from Texas Instruments is a low-dropout positive voltage regulator delivering 8 V at up to 750 mA, featuring dropout voltage < 0.6 V at full load, 60-V load-dump protection, and internal thermal/overcurrent limiting. It is designed for battery-powered systems requiring stable standby power with reverse-battery tolerance.
For engineers reviewing the TL750M08CKTPRG3 datasheet, TL750M08CKTPRG3 pinout, TL750M08CKTPRG3 application, or TL750M08CKTPRG3 equivalent, key selection criteria include dropout performance under 750 mA load, 60-V transient input handling, quiescent current stability across temperature, and compatibility with 10-μF tantalum output capacitors per TI's ESR guidelines.
Technical Context
The TL750M08CKTPRG3 integrates bandgap reference, current-limiting circuitry, overvoltage shutdown, and thermal overload protection in a single monolithic IC. Its control loop relies on external output capacitor ESR (0.13 Ω–2 Ω) for stability across 5–750 mA load range.
It operates over 0°C to 125°C virtual junction temperature and supports input voltages from 9 V to 26 V. Protection features include 60-V transient input tolerance, –50-V reverse-battery capability (100 ms), and internal foldback current limiting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 8 V ±0.08 V (TYP) at 300 mA; ±0.16 V over 0°C–125°C - ensures tight regulation for sensitive analog or microcontroller supply rails |
| Max Output Current | 750 mA continuous - supports moderate-power subsystems without external pass devices |
| Dropout Voltage | 0.6 V at 750 mA - enables operation with only 0.6 V headroom above output, critical for low-voltage battery systems |
| Input Voltage Range | 9 V to 26 V (recommended); withstands 60-V transients - suitable for 12-V automotive and industrial bus environments |
| Quiescent Current | 60–75 mA at 750 mA load - remains stable under full load, minimizing standby power loss |
| Ripple Rejection | 50–55 dB at 120 Hz - suppresses low-frequency noise from switching pre-regulators or alternators |
| Thermal Protection | Internal thermal shutdown - prevents damage during sustained overload or poor heatsinking |
Pinout & Package
TL750M08CKTPRG3 uses the PowerFLEX™ KTP (TO-252 variation AC) plastic flange-mount package. The center lead (Pin 2) is electrically connected to the thermal tab/mounting base, enabling direct heatsinking to PCB copper or chassis.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (INPUT) | Regulator input | Accepts 9–26 V DC input; requires 0.1-μF ceramic bypass capacitor |
| Pin 2 (COMMON) | Ground/reference terminal | Electrically tied to thermal tab; must be connected to low-impedance ground plane for thermal and noise control |
| Pin 3 (OUTPUT) | Regulated output | Delivers 8 V ±0.16 V; requires 10-μF tantalum capacitor with ESR 0.13–2 Ω for stability |
Key Features
| Feature | Design Value |
|---|---|
| 60-V Load-Dump Protection | Withstands automotive ISO 7637-2 pulse 5a transients without external clamping |
| Reverse-Battery Tolerance | Survives –50 V for 100 ms - eliminates need for series diode in battery-reversal-prone applications |
| Low Dropout at Full Load | 0.6 V dropout at 750 mA enables use with depleted 12-V batteries down to ~8.6 V input |
| Integrated Thermal Shutdown | Self-protects against overheating due to inadequate heatsinking or ambient >125°C |
| Overcurrent Foldback Limiting | Reduces output current during short-circuit to limit power dissipation and enable safe auto-recovery |
Applications
| Automotive Body Control Module | Industrial Sensor Transmitter |

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 |
|---|---|---|---|
| TL750M08CKVURG3 | Same electrical specs; KVU PowerFLEX™ package (3-pin, flange-mount) with higher θJA (28°C/W) vs KTP (25.3°C/W) | Designed for surface-mount reflow assembly; larger footprint but compatible with automated pick-and-place | Select for volume SMT production where tape-and-reel (2500/reel) and RoHS-compliant green packaging are required |
| TL750M08CKCS | Identical regulation and protection specs; TO-220 KCS package with isolated tab and vertical mounting | Enables bolt-down heatsinking and through-hole prototyping; no thermal pad soldering required | Select for lab validation, low-volume builds, or designs needing mechanical robustness and manual serviceability |
Compared with TL750M08CKTPRG3, TL750M08CKVURG3 offers identical regulation but targets high-volume SMT lines, while TL750M08CKCS provides through-hole flexibility and easier thermal management via screw-mount heatsinks - all three share the same 8-V output, 750-mA capability, and 60-V transient protection.

FAQ
What is the maximum input voltage the TL750M08CKTPRG3 can handle?
The TL750M08CKTPRG3 supports a recommended continuous input voltage range of 9 V to 26 V. It is rated for transient input voltage up to 60 V per ISO 7637-2 Pulse 5a, and can withstand –50 V reverse input for 100 ms. These ratings are validated per TI's absolute maximum specifications and make the TL750M08CKTPRG3 suitable for 12-V automotive and industrial bus applications with harsh electrical environments.
Does the TL750M08CKTPRG3 require an external capacitor on the output?
Yes, the TL750M08CKTPRG3 requires a 10-μF tantalum output capacitor with ESR between 0.13 Ω and 2 Ω for stable operation across its full 5–750 mA load range. TI's datasheet specifies this capacitor as part of the control loop; using outside this ESR window risks oscillation or poor transient response. Ceramic capacitors alone are not recommended unless series resistance is added to emulate the required ESR.
Is the thermal tab of the TL750M08CKTPRG3 electrically connected to any pin?
Yes, the thermal tab of the TL750M08CKTPRG3 is electrically connected to Pin 2 (COMMON). This connection is explicitly stated in TI's mechanical drawings and functional block diagram. Therefore, the mounting base must be tied to the system ground plane - not left floating or insulated - to ensure proper thermal conduction and electrical reference integrity.
What protection features does the TL750M08CKTPRG3 include?
The TL750M08CKTPRG3 integrates four key protection features: (1) 60-V load-dump transient immunity, (2) –50-V reverse-battery tolerance (100 ms), (3) internal thermal shutdown activated above virtual junction temperature limits, and (4) foldback overcurrent limiting. These are implemented on-die and require no external components, distinguishing it from basic LDOs that rely on discrete protection circuitry.
Can the TL750M08CKTPRG3 be used in automotive applications?
Yes, the TL750M08CKTPRG3 is qualified for automotive environments per its 60-V load-dump rating, –50-V reverse-battery capability, and operation over 0°C to 125°C virtual junction temperature. While the standard TL750M08CKTPRG3 is not AEC-Q100 certified, TI offers the automotive-grade TL750M08-Q1 variant. For non-safety-critical body electronics (e.g., interior lighting, door modules), the TL750M08CKTPRG3 has been widely deployed with appropriate system-level validation.
