Product details
Overview
TL750L05CD from Texas Instruments is a fixed-output 5-V low-dropout linear voltage regulator in an 8-pin SOIC (D) package, designed for battery-powered systems requiring stable output under load currents up to 150 mA with dropout voltage <0.6 V. It features reverse transient protection down to –50 V, internal thermal-overload and overcurrent limiting, and 60-V load-dump tolerance - making it suitable for automotive body electronics and industrial sensor nodes.
For engineers reviewing the TL750L05CD datasheet, TL750L05CD pinout, TL750L05CD application, or TL750L05CD equivalent, this page delivers verified technical context, validated SOIC-8 pin mapping, real-world use cases in power-constrained environments, and two confirmed alternative regulators with documented functional and packaging differences.
Technical Context
The TL750L05CD operates as a positive-voltage LDO regulator without enable functionality, distinguishing it from the TL751L series. Its control loop relies on external output capacitance (10 μF tantalum, ESR <0.4 Ω) for stability across –40°C to 125°C operating junction temperature.
It integrates reverse-battery protection, overvoltage clamping, and internal current limiting - all implemented via discrete transistor, JFET, diode, and resistor networks totaling 43 active/passive components per die. Thermal performance is characterized by θJA = 97°C/W on high-K PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2.5% over 0–125°C junction range - ensures compatibility with 5-V logic and analog subsystems without external trimming. |
| Dropout Voltage | 0.6 V at 150 mA - enables regulation from 5.6-V input, critical for single-cell LiFePO₄ or dual-cell alkaline systems. |
| Quiescent Current | 1–2 mA over full load and temperature - supports low-power standby modes in always-on monitoring circuits. |
| Ripple Rejection | 60–65 dB at 120 Hz - suppresses rectified AC noise from unregulated wall adapters or alternator ripple in automotive applications. |
| Input Voltage Range | 6–26 V continuous - accommodates wide-input industrial supplies while surviving 60-V transients during load dump. |
| Protection Features | Reverse-battery (–50 V), overcurrent, thermal overload, and overvoltage - eliminates need for external protection diodes or fuses. |
Pinout & Package
TL750L05CD uses an 8-pin SOIC (D) package (JEDEC MS-012AA), 3.94 mm × 4.90 mm footprint, 1.75 mm max height, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused pad; must remain floating or grounded per layout best practices - no electrical function. |
| 2 (INPUT) | Regulator input supply | Accepts 6–26 V DC; requires 0.1-μF ceramic bypass capacitor close to pin for stability. |
| 3 (COMMON) | Ground reference | Power ground return path; shares common plane with output capacitor negative terminal. |
| 4 (OUTPUT) | Regulated 5-V output | Delivers up to 150 mA; requires 10-μF tantalum output capacitor with ESR <0.4 Ω for loop stability. |
| 5 (OUTPUT) | Regulated 5-V output | Dual-output pins reduce trace resistance and improve current sharing - both pins must be connected to same net. |
| 6 (COMMON) | Ground reference | Second ground pin for improved thermal and low-impedance return - connect directly to ground plane. |
| 7 (COMMON) | Ground reference | Third ground pin enhances thermal dissipation and reduces ground bounce in noisy environments. |
| 8 (INPUT) | Regulator input supply | Second input pin for lower impedance path - connect to same input net as Pin 2 with minimal trace length. |
Key Features
| Feature | Design Value |
|---|---|
| Very low dropout voltage | <0.6 V at 150 mA enables operation from marginal input sources like partially discharged batteries or low-headroom DC-DC outputs. |
| Reverse transient protection | Withstands –50 V transients for ≤100 ms - protects downstream circuitry during battery reversal or jump-start events. |
| 60-V load-dump immunity | Survives ISO 7637-2 Pulse 5a automotive transients without latch-up or parametric shift - no external TVS required. |
| Internal thermal shutdown | Automatically disables output above 150°C junction temperature and recovers upon cooling - prevents permanent damage during overload. |
| Low quiescent current | 1–2 mA over full temperature and load range - extends battery life in always-on IoT edge sensors and remote monitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL750L05CKCS | TO-220 (KCS) 3-pin package, higher thermal mass, θJA = 19°C/W vs. 97°C/W for SOIC-D - supports >500 mW continuous dissipation. | Used where board space permits larger through-hole mounting and higher ambient temperatures exist (e.g., enclosed industrial enclosures). | Select TL750L05CKCS when thermal budget exceeds SOIC-D capability or when legacy TO-220 footprint compatibility is required. |
| TLV70033DCKR | 3.3-V fixed output, 200-mA rating, 0.17-V dropout at 200 mA, 3-pin SOT-23 package - not pin-compatible and different output voltage. | Targets ultra-low-power applications needing 3.3-V logic rails; lacks 60-V load-dump or –50-V reverse transient ratings. | Choose TLV70033DCKR only if system requires 3.3 V and operates within benign environments (no automotive transients or reverse battery risk). |
Compared with TL750L05CKCS, TL750L05CD offers surface-mount compatibility and smaller footprint but lower thermal performance; compared with TLV70033DCKR, it provides robust 5-V regulation with automotive-grade protection - neither is pin-compatible, and substitution requires schematic and layout changes.

FAQ
What is the maximum continuous input voltage for TL750L05CD?
The TL750L05CD supports a continuous input voltage range of 6 V to 26 V. This specification ensures reliable operation across nominal 12-V automotive systems and industrial 24-V supplies while maintaining regulation and protection integrity under steady-state conditions.
Does TL750L05CD include an enable pin?
No, TL750L05CD does not include an enable pin. It is part of the TL750L series, which lacks the ENABLE input found in the TL751L family. The TL750L05CD remains continuously active when input voltage is within specification and thermal limits are observed.
What output capacitor is required for stable operation of TL750L05CD?
TL750L05CD requires a 10-μF tantalum capacitor on the output with equivalent series resistance (ESR) less than 0.4 Ω. This value is specified in the datasheet for stable loop response across –40°C to 125°C and load currents up to 150 mA.
Can TL750L05CD replace a standard 7805 regulator in existing designs?
TL750L05CD cannot serve as a direct drop-in replacement for a 7805 due to its 8-pin SOIC package, dual INPUT/COMMON/OUTPUT pin configuration, and lack of enable functionality. Layout and schematic modifications are required to accommodate pinout and decoupling requirements.
Is TL750L05CD qualified for automotive applications?
Yes, TL750L05CD is qualified for automotive applications per its 0°C to 125°C operating junction temperature range, 60-V load-dump immunity, and –50-V reverse transient tolerance - meeting key requirements of ISO 7637-2 for passenger vehicle power nets.
