Texas Instruments LP38856S-1-2 is a fixed 1.2V positive linear voltage regulator designed for high-current applications. With an output current capability of 3A, this device is suitable for power-intensive systems. It features an enable pin for control and offers robust protection against over current, over temperature, and short circuit conditions, as well as Under Voltage Lockout (UVLO). The quiescent current is rated at 300 µA, with a maximum supply current of 15 mA. The input voltage maximum is 5.5V, and the dropout voltage is 0.45V at 3A. This component boasts excellent power supply ripple rejection (PSRR) ranging from 80dB to 65dB across a frequency range of 120Hz to 1kHz. The LP38856S-1-2 is housed in a TO-263 (DDPAK-5) surface-mount package, facilitating integration into compact designs. It operates within an ambient temperature range of -40°C to 125°C and finds application in sectors such as automotive and industrial power management.
