LF18CPT-TR Description

Short technical summary and product information.

The STMicroelectronics LF18CPT-TR is a linear voltage regulator designed for applications requiring a stable 1.8V output. It can deliver up to 500mA of current and operates within a temperature range of -40°C to 125°C. This device features over-current and over-temperature protection for enhanced reliability.

 

It is housed in a PPAK package, specifically a TO-252-5, DPak (4 Leads + Tab), TO-252AD, suitable for surface mounting. The regulator has a voltage dropout of 0.7V at 200mA and offers good power supply ripple rejection (PSRR) between 82dB and 60dB across a frequency range of 120Hz to 10kHz. The 'Enable' control feature allows for power management.

 

This component is ideal for various power management circuits where a fixed, regulated voltage is needed. Its robust protection features and wide operating temperature make it suitable for demanding environments.
