Texas Instruments TL750L05CKTER

Summary of TL750L05CKTER Linear Voltage Regulator by Texas Instruments

The TL750L05CKTER from Texas Instruments is a member of the TL750L series of low-dropout, fixed-output positive voltage regulators. This model delivers a regulated 5V output at up to 150mA, housed in a compact 3-PowerFLEX™ (TO-252-4, DPAK) surface mount package. Aimed at engineers requiring robust performance in battery-powered or standby systems, the TL750L05CKTER combines effective power regulation with integrated system protection features suitable for automotive, industrial, and general-purpose electronics.

Main Attributes and Performance TL750L05CKTER 5V 150mA Voltage Regulator

One of the TL750L05CKTER’s core strengths is its ability to maintain output regulation with a very low dropout voltage—less than 0.6V at full load (150mA)—allowing efficient operation when input voltage approaches the output limit. The 65dB power supply rejection ratio (PSRR) at 120Hz ensures good noise filtering and stable downstream loads.

Operating from input supplies up to 26V, the device keeps quiescent current to a minimum (2mA typical, 12mA max supply current), making it well-suited for applications where energy conservation is paramount. Integrated design minimizes the need for external circuitry, offering simplicity without sacrificing power integrity.

Operation Details TL750L05CKTER Protection, Control, and Working Conditions

The TL750L05CKTER employs comprehensive protection mechanisms critical in modern systems: overcurrent-limiting, internal thermal-overload, overvoltage defense, and reverse polarity protection (with transient tolerance down to -50V and 60V load-dump protection). Such features are vital in automotive and industrial environments characterized by frequent voltage surges or power fluctuations.

The device is specified for an operating junction temperature range from 0°C to 125°C, offering flexibility in high-temperature deployments. For optimal loop stability, attention must be given to output capacitance: recommended is a 10μF capacitor with an equivalent series resistance (ESR) under 0.4Ω. This selection ensures robust transient response and minimal output voltage deviation.

Physical Variants and Integration TL750L05CKTER Package Choices and Board Compatibility

The TL750L05CKTER is supplied in the 3-PowerFLEX™ (TO-252-4, DPAK) format for efficient heat dissipation and automated PCB assembly. The compact surface-mount package supports integration into modern, high-density circuit boards, with land pattern and stencil design requirements outlined for reliable soldering and thermal management. Designers can reference provided IPC and JEDEC standards for board layout and assembly, ensuring compatibility with standard industry processes.

Additional package formats in the TL750L series include TO-220 and TO-92, offering flexibility for through-hole versus surface-mount requirements across varied assembly scenarios. Each package recommendation specifies pad geometry, solder mask tolerances, and board integration guidance to maximize mechanical stability and thermal performance.

Implementation Guidelines Engineering Insights for TL750L05CKTER Applications

Engineers integrating the TL750L05CKTER into circuits must evaluate the interplay of dropout voltage, load current, and input supply margin to guarantee continuous operation under all expected system conditions. For instance, battery-powered designs leveraging low quiescent current support extended operation in standby modes, while automotive electronics benefit from built-in surge protection.

Attention to output capacitance and ESR is critical for regulator stability; thermal considerations must be managed through proper package and PCB pad design. System reliability is further enhanced by features such as reverse polarity and load-dump protection, helping safeguard both the regulator and connected electronics in harsh environments.

Alternative or Replacement Options Comparable Devices to TL750L05CKTER Within TI’s Product Range

While the TL750L05CKTER has reached obsolete status, designers seeking replacements within the Texas Instruments lineup can consider models in the TL751L series. The TL751L, for example, offers similar fixed voltage outputs with the addition of a TTL/CMOS-compatible enable function for output control, and maintains many of the robust protection and low dropout attributes of the TL750L05CKTER. For higher output currents or additional package options, related TI series such as the TPS7xx family may offer alternatives tailored to specific application demands.
