Product details
Overview
TL750L05CKVURG3 from Texas Instruments is a 5-V fixed-output, low-dropout linear voltage regulator in TO-252 (KVU) package with 3 terminals. It delivers up to 150 mA output current, features <0.6 V dropout at full load, reverse transient protection down to –50 V, and operates across 0°C to 125°C junction temperature. It is designed for battery-powered systems requiring stable, low-quiescent-current regulation.
For engineers reviewing the TL750L05CKVURG3 datasheet, TL750L05CKVURG3 pinout, TL750L05CKVURG3 application, or TL750L05CKVURG3 equivalent, key selection criteria include dropout voltage under 150 mA load, 60-V load-dump immunity, thermal-overload protection, and compatibility with 10-μF output capacitors having ESR <0.4 Ω.
Technical Context
The TL750L05CKVURG3 implements a PNP pass transistor architecture enabling ultra-low dropout operation. Its internal circuitry integrates overcurrent limiting, thermal shutdown, reverse-battery protection, and overvoltage clamping-critical for automotive and industrial power rails exposed to load dump and polarity reversal.
Unlike the TL751L series, TL750L05CKVURG3 lacks an ENABLE input and operates continuously when input voltage is within 6 V–26 V. Its quiescent current remains ≤2 mA across full load and temperature range, supporting standby power integrity without external control logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2.5% (4.75–5.25 V over 0°C–125°C), tightly regulated for microcontroller I/O and analog sensor biasing |
| Dropout Voltage | 0.6 V max at 150 mA, enabling regulation from 5.6 V input-ideal for single-cell LiFePO₄ or dual-cell alkaline systems |
| Input Voltage Range | 6 V to 26 V continuous, with 60-V transient load-dump tolerance-meets ISO 7637-2 Pulse 5a requirements |
| Quiescent Current | ≤2 mA over full load and temperature, minimizing battery drain in always-on monitoring circuits |
| Ripple Rejection | 60 dB min at 120 Hz, suppressing AC line noise and switching supply coupling into sensitive analog stages |
| Thermal Protection | Internal thermal-overload shutdown with automatic recovery, preventing latch-up during sustained overload or poor heatsinking |
| Reverse Transient | Withstands –50 V transients (t ≤100 ms), protecting against accidental battery reversal in field-serviceable equipment |
Pinout & Package
TL750L05CKVURG3 uses the TO-252 (KVU) surface-mount package: 3-terminal, exposed thermal pad, 2.52 mm max height, JEDEC-standard footprint optimized for PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INPUT) | Regulator input | Accepts unregulated DC input; requires 0.1-μF ceramic bypass capacitor close to pin |
| 2 (COMMON) | Ground reference | Common return path for input and output; must connect directly to thermal pad and low-impedance ground plane |
| 3 (OUTPUT) | Regulated output | Delivers stable 5 V; requires 10-μF tantalum or low-ESR capacitor (ESR <0.4 Ω) for loop stability |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout voltage | 0.6 V max at 150 mA enables operation from marginal input sources like aging batteries or post-dropper supplies |
| Reverse transient protection | Rated for –50 V transients (100 ms), eliminating need for external series diode in reverse-polarity-prone environments |
| Load-dump immunity | 60-V transient rating meets automotive load-dump stress testing per ISO 7637-2, reducing system-level protection components |
| Thermal and overcurrent protection | Self-limiting behavior prevents damage during short-circuit or high-ambient conditions without external foldback circuitry |
| Low-noise output | 500 μV RMS output noise (10 Hz–100 kHz) supports clean power for ADC references and RF front-end biasing |

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 |
|---|---|---|---|
| TL750L05CDR | SOIC-8 package (8-pin), higher thermal resistance (θJA = 97°C/W vs. 30.3°C/W), no exposed thermal pad | Suitable for low-power, non-thermally constrained PCBs; not recommended for >100 mA continuous loads in compact enclosures | Select TL750L05CDR only if board layout lacks thermal pad capability or if SOIC footprint is already standardized. |
| LM2931AZ-5.0/NOPB | TO-92 package, 100 mA output, 0.6 V dropout, but no 60-V load-dump rating-only rated for 40 V transient | Acceptable for consumer-grade portable devices where automotive-grade surge immunity is unnecessary | Choose LM2931AZ-5.0/NOPB for cost-sensitive, low-current applications without harsh electrical environment requirements. |
Compared with TL750L05CDR and LM2931AZ-5.0/NOPB, TL750L05CKVURG3 provides superior thermal performance via its TO-252 exposed pad and uniquely meets 60-V load-dump immunity-making it the only option qualified for under-hood automotive and industrial power-rail applications demanding robustness and sustained 150 mA delivery.

FAQ
What is the maximum continuous input voltage for TL750L05CKVURG3?
The TL750L05CKVURG3 supports a continuous input voltage range of 6 V to 26 V. Absolute maximum continuous input voltage is 26 V; exceeding this may cause permanent damage. Transient input voltage up to 60 V is allowed for ≤100 ms per ISO 7637-2 Pulse 5a test profiles.
Does TL750L05CKVURG3 have an enable pin?
No, TL750L05CKVURG3 does not include an ENABLE input. It is part of the TL750L series, which operates continuously when valid input voltage is applied. For enable functionality, consider the TL751L05CKVURG3 variant, which adds TTL/CMOS-compatible ENABLE control.
What output capacitor is required for stable operation of TL750L05CKVURG3?
TL750L05CKVURG3 requires a 10-μF output capacitor with equivalent series resistance (ESR) less than 0.4 Ω-typically a tantalum or low-ESR polymer capacitor. Ceramic capacitors alone are insufficient due to near-zero ESR causing potential instability; a minimum ESR is essential for loop compensation.
Can TL750L05CKVURG3 be used in automotive applications?
Yes, TL750L05CKVURG3 is qualified for automotive use: it withstands 60-V load-dump transients and –50-V reverse-battery events, operates from –40°C to +125°C (junction), and is RoHS-compliant. Its TO-252 package supports robust thermal management required in engine bay or chassis-mounted ECUs.
What is the thermal resistance (θJA) of TL750L05CKVURG3 in standard PCB layout?
The published θJA for TL750L05CKVURG3 is 30.3°C/W under JEDEC High-K board conditions (JESD 51-5). This value assumes proper connection of the exposed thermal pad to a ≥1-in² copper pour with ≥4 thermal vias. Without thermal pad connection, θJA degrades significantly-designers must follow TI's SLMA002/SLMA004 guidelines.
