The LD2981CM30TR from STMicroelectronics is a linear voltage regulator designed for efficient power management. It provides a stable, fixed 3V output voltage with a maximum output current of 100mA.
Key electrical specifications include a maximum input voltage of 16V and a low dropout voltage of 0.375V at 100mA. The quiescent current is 150µA, with a maximum supply current of 2.6mA, making it suitable for power-sensitive applications. It also features a Power Supply Rejection Ratio (PSRR) of 63dB at 1kHz.
This device includes enable control features and protection against over-current and over-temperature conditions. It operates within a wide temperature range of -40°C to 125°C.
The LD2981CM30TR is housed in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount package, facilitating integration into space-constrained designs. It is supplied on tape and reel.
