Product details

The onsemi LP2950CDT-5.0 is a single-output positive LDO voltage regulator delivering a fixed 5V output at up to 100 mA. The fixed output means no external resistor divider is needed — the BOM stays lean. The maximum dropout voltage is 0.6V at the full 100 mA load, so the input rail needs at least 5.6V to maintain regulation. Quiescent current is 120 µA typical, which keeps the idle power draw low in always-on circuits.

Temperature grade and protection — where it fits

Built-in over-current and over-temperature protection give it a basic safety net against load faults or thermal runaway.
