TPL730F18-CR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TPL730F18-CR is a positive, fixed-output linear low-dropout (LDO) voltage regulator manufactured by 3PEAK. It provides a fixed output voltage of 1.8V with a maximum continuous output current of 300mA. The device supports an input voltage range from 2.4V to 5.5V and features a maximum dropout voltage of 0.25V at full load. It incorporates comprehensive protection mechanisms including overcurrent protection, thermal shutdown, and under-voltage lockout (UVLO). The regulator operates reliably across an extended junction temperature range of -40°C to +125°C and is housed in a compact SC-70-5 surface-mount package.
