LDK120C30R Description

Short technical summary and product information.

The STMicroelectronics LDK120C30R is a linear voltage regulator designed for applications requiring a stable 3V output at up to 200mA. This device features integrated over-current and over-temperature protection, enhancing system reliability.

 

With a low voltage dropout of 0.3V at 200mA and a PSRR of 55dB (120Hz ~ 10kHz), the LDK120C30R is suitable for power-sensitive applications. It operates across a temperature range of -40°C to 125°C.

 

The regulator is available in a compact SOT-323-5 surface-mount package, making it ideal for space-constrained designs. Its fixed output type and positive output configuration, along with an enable control feature, provide design flexibility.
