Product details
Overview
TL750L08CLPE3 from Texas Instruments is a fixed-output 8-V low-dropout linear voltage regulator in TO-92 (LP) package, delivering up to 150 mA with dropout voltage <0.6 V at full load, reverse transient protection down to –50 V, and internal thermal/overcurrent protection. It serves as a primary power supply for battery-powered microcontroller peripherals, sensor interfaces, and automotive body electronics requiring stable 8-V bias under variable input conditions.
For engineers reviewing the TL750L08CLPE3 datasheet, TL750L08CLPE3 pinout, TL750L08CLPE3 application, or TL750L08CLPE3 equivalent, key selection criteria include its 8-V output tolerance (±4% over 0°C–125°C), 60-V load-dump immunity, quiescent current ≤2 mA across operating range, and compatibility with standard 10-μF tantalum output capacitors per TI's stability guidelines.
Technical Context
The TL750L08CLPE3 implements a PNP pass transistor architecture enabling ultra-low dropout performance while maintaining robust reverse-battery and load-dump protection. Its internal circuitry integrates overvoltage clamping, thermal shutdown, and foldback current limiting-no external enable or feedback components required.
Unlike the TL751L series, TL750L08CLPE3 lacks an ENABLE pin and operates continuously when input voltage exceeds minimum startup threshold (9 V). Its SOIC-8 variants (e.g., TL750L08CD) share identical electrical specs but differ in thermal resistance (θJA = 97°C/W vs. 140°C/W for TO-92).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 8.0 V ±4% (7.68–8.32 V at 25°C; 7.6–8.4 V over 0°C–125°C), ensuring stable logic-level bias for 8-V analog front-ends. |
| Max Output Current | 150 mA continuous, sufficient for powering multiple low-power op-amps or MCU I/O banks without derating. |
| Dropout Voltage | 0.6 V max at 150 mA, enabling operation with input as low as 8.6 V-critical for single-cell LiFePO₄ or degraded lead-acid systems. |
| Input Voltage Range | 9–26 V DC, supporting wide automotive battery transients including ISO 7637-2 pulse 5a (60-V load dump). |
| Quiescent Current | ≤2 mA over full temperature and load range, minimizing standby power loss in always-on vehicle modules. |
| Ripple Rejection | 60–65 dB at 120 Hz, suppressing alternator ripple and enabling clean analog supply in noisy engine compartments. |
| Thermal Resistance | θJA = 140°C/W (TO-92 LP), requiring minimal copper area for thermal management in space-constrained PCBs. |
Pinout & Package
TL750L08CLPE3 uses the TO-92 (LP / TO-226AA) 3-pin through-hole package with standard pinout: Pin 1 = INPUT, Pin 2 = COMMON (GND), Pin 3 = OUTPUT. The package provides mechanical robustness for industrial vibration environments and supports hand-soldering or wave soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | INPUT | Unregulated positive input (9–26 V); connects to bulk capacitor and upstream power source. |
| Pin 2 | COMMON | Ground reference shared by input and output; must be low-impedance path to system GND plane. |
| Pin 3 | OUTPUT | Regulated 8-V output; requires 10-μF tantalum capacitor (ESR <0.4 Ω) for loop stability per TI design guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Reverse transient protection | Withstands –50 V transients (t ≤100 ms), eliminating need for external reverse-polarity diode in automotive harnesses. |
| Load-dump immunity | Fully rated for 60-V transients per ISO 7637-2, protecting downstream circuitry during alternator field collapse. |
| Internal thermal shutdown | Activates at ~150°C junction temperature, preventing permanent damage during sustained overload or poor heatsinking. |
| Low-noise regulation | 500 μV RMS output noise (10 Hz–100 kHz), suitable for precision ADC references and low-distortion audio preamps. |
| Overcurrent limiting | Foldback current limit protects against short-circuit faults while minimizing power dissipation during fault conditions. |

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 |
|---|---|---|---|
| TL750L08CD | SOIC-8 package (8-pin), θJA = 97°C/W, same electrical specs, no enable pin. | Better thermal performance for surface-mount designs; requires PCB rework for TO-92 footprint replacement. | Select for higher-power density layouts where board space permits SMT assembly and thermal vias. |
| LM2931T-8.0 | TO-220 package, 100 mA max output, 0.6 V dropout, no 60-V load-dump rating. | Limited to lower-current applications; lacks TI's integrated 60-V transient protection. | Choose only if cost sensitivity outweighs automotive-grade transient immunity requirements. |
Compared with TL750L08CD and LM2931T-8.0, TL750L08CLPE3 uniquely combines TO-92 mechanical simplicity, 150 mA capability, and full 60-V/–50-V transient immunity-making it optimal for legacy through-hole automotive modules where reliability trumps miniaturization.

FAQ
What is the maximum input voltage rating for TL750L08CLPE3?
The TL750L08CLPE3 has a continuous input voltage rating of 26 V and a transient input voltage rating of 60 V (per ISO 7637-2 pulse 5a, t ≤100 ms). This allows safe operation in 24-V truck systems and during alternator load-dump events. Exceeding 60 V transient or 26 V continuous risks permanent damage per absolute maximum ratings.
Does TL750L08CLPE3 require an external capacitor on the output?
Yes, TL750L08CLPE3 requires a 10-μF tantalum capacitor with ESR <0.4 Ω on the output for stable regulation across temperature and load. TI's datasheet specifies this value as critical for control-loop compensation; using ceramic or aluminum electrolytic capacitors without verifying ESR may cause oscillation or poor transient response.
Can TL750L08CLPE3 be used in reverse-battery conditions?
Yes, TL750L08CLPE3 incorporates internal reverse-battery protection and withstands –15 V continuous and –50 V transient reverse input voltage (t ≤100 ms). This eliminates the need for an external series diode in automotive applications where battery terminals may be accidentally reversed during service.
What is the output voltage tolerance of TL750L08CLPE3 over temperature?
The TL750L08CLPE3 maintains an output voltage tolerance of ±4% (7.6–8.4 V) over the full operating junction temperature range of 0°C to 125°C. At 25°C, the tighter tolerance is ±4% (7.68–8.32 V), verified per TI's production test limits in the SLVS017U datasheet.
Is TL750L08CLPE3 pin-compatible with other regulators in the TL750L family?
Yes, all TL750L variants-including TL750L05CLPE3, TL750L10CLPE3, and TL750L12CLPE3-share identical TO-92 (LP) pinout (Pin 1 = INPUT, Pin 2 = COMMON, Pin 3 = OUTPUT) and thermal characteristics. Only the output voltage differs; no PCB layout changes are needed when substituting between these fixed-voltage members.
