SP6203EM5-L-3-0

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

The SP6203EM5-L-3-0 is a low-noise, fixed-output CMOS Low Dropout (LDO) voltage regulator manufactured by MaxLinear. It provides a stable 3.0V output with a maximum load current of 300mA. The device operates within an input voltage range of 2.5V to 6V and features a typical dropout voltage of 0.3V at full load. Packaged in a compact SOT-23-5 surface-mount format, it offers high power supply rejection ratio (PSRR) for noise-sensitive applications. The regulator includes internal protection mechanisms such as current limiting and thermal shutdown to ensure reliable operation across industrial temperature ranges.
