Its 0.6V maximum dropout at 100 mA means the input rail can dip to 3.6V and still hold the output in regulation — a practical margin for 5V or 3.7V Li-ion supplies that sag under load. ## Dropout and quiescent current trade-offs Quiescent current is 120 µA typical, rising to a maximum supply current of 14 mA under heavy load or fault conditions. The low idle current suits battery-powered equipment where every microamp counts, but the 14 mA ceiling means the pass element can draw significant bias during dropout — factor that into thermal calculations for the TO-92-3 package. Protection features include over-current and over-temperature shutdown, which prevent the part from self-destructing under a sustained short or excessive ambient temperature. No reverse-current protection is listed, so a blocking diode on the output is advisable if the input can collapse while the output stays high. ## Through-hole package and temperature grade The LP2950-30LP is housed in a TO-92-3 (TO-226AA) through-hole package.","metaTitle":"LP2950-30LP Texas Instruments 3V Fixed LDO Regulator","metaDescription":"LP2950-30LP from TI: 3V fixed output, 100mA LDO, 0.6V dropout at full load, -40°C to 125°C.
