What is L4810CV used for?
L4810CV is commonly used in industrial control panels, audio amplifiers, and telecommunications equipment requiring a stable 10 V regulated rail from a higher-voltage DC bus. Its TO-220 package and high input voltage tolerance make it suitable for post-regulation stages in power supplies operating from a 15 V to 24 V intermediate bus.

Frequently Asked Questions
What is the minimum input voltage required for L4810CV to maintain a regulated 10 V output at 400 mA?
L4810CV has a dropout voltage of 900 mV maximum, so the input must be at least 10.9 V to keep the output regulated at 10 V. The specified input range starts at 14 V, giving a comfortable 3 V headroom above the minimum dropout at full 400 mA load.
Can L4810CV handle load transients in a 24 V industrial supply without an external pass transistor?
L4810CV is rated for 400 mA continuous output current with its integrated pass transistor, which is sufficient for most 10 V logic or sensor rails in industrial systems powered from a 24 V supply. For loads exceeding 400 mA, an external pass transistor must be added, as the internal device will enter thermal protection above its rated current.
What thermal management approach is recommended when L4810CV operates near its 400 mA current limit in an enclosure?
L4810CV in a TO-220 package can be mounted to an aluminum heatsink via the metal tab. At 400 mA with a 14 V input and 10 V output, the power dissipation is approximately 1.6 W. Without a heatsink, the junction temperature rise can reach 80°C above ambient, requiring a heatsink with a thermal resistance below 50°C/W to stay within the rated operating range.
Is L4810CV RoHS-compliant and what does the Pbfree Code 'No' mean for procurement?
The L4810CV Pbfree Code is listed as 'No,' indicating this part uses a tin-lead solder finish and is not RoHS-compliant in its standard form. Procurement teams targeting EU RoHS-2 or China RoHS markets should verify whether an alternative lead-free variant is available or select a RoHS-compliant LDO with equivalent 10 V, 400 mA specifications.
