The STMicroelectronics LF33CPT is a fixed 3.3V positive linear voltage regulator with a 500mA output capability. This device features an enable pin for control and offers robust protection against over-current and over-temperature conditions. Operating with a maximum input voltage of 16V, it provides a typical quiescent current of 1mA and a maximum supply current of 12mA. The LF33CPT exhibits good power supply rejection ratio (PSRR) across a frequency range, with values typically between 80dB and 65dB. Its low dropout voltage is 0.7V at 500mA, making it suitable for power-sensitive applications. The TO-252-5, DPAK package facilitates surface mounting. This component is commonly integrated into automotive, industrial, and consumer electronics power management subsystems.
