LM78L05ACM/NOPB.. – TEXAS INSTRUMENTS

The LM78L05ACM/NOPB is a low-power, three-terminal positive voltage regulator integrated circuit from Texas Instruments. Specifically, the “/NOPB” suffix denotes a lead-free, no-halogen package. This particular part operates with a fixed output voltage of 5.0V ±5%, requiring an input voltage ranging from 7.0V to 20V. Its low quiescent current of typically 8mA contributes to its high efficiency, especially relevant in battery-powered applications. Packaged in a space-saving SOT-23-5 surface-mount format, it’s ideal for high-density PCB designs._x000D_

The LM78L05ACM/NOPB features built-in thermal overload protection and short-circuit protection, enhancing its robustness. Its output current capability is limited to 100mA, making it suitable for low-current applications such as powering microcontrollers, operational amplifiers, and other low-power peripherals. The low dropout voltage characteristic (typically 1.7V) allows for efficient operation with minimal input-output voltage differences. However, for currents exceeding 100mA, a higher-current regulator would be necessary. The device’s low power dissipation and small form factor make it a strong choice for portable devices and applications where minimizing heat generation is crucial.
