Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
STMicroelectronics LF33CDT is a positive fixed output linear voltage regulator. This component delivers a stable 3.3V output with a maximum current capability of 500mA. Featuring a low dropout voltage of 0.7V at 500mA, it is suitable for applications requiring efficient power regulation. The device offers robust protection mechanisms including over-current and over-temperature shutdown. Its quiescent current is 1mA, with a supply current not exceeding 12mA. The LF33CDT exhibits excellent power supply rejection ratio (PSRR) ranging from 80dB to 65dB across a frequency band of 120Hz to 65dB. Designed for surface mount applications, it is housed in a TO-252-3, DPAK (2 Leads + Tab), SC-63 package. This regulator is commonly utilized in automotive, industrial, and consumer electronics power management systems. The operating temperature range is -40°C to 125°C.
