LDO-3V3-SOT223
3.3V low-dropout linear regulator
Stable 3.3V linear regulator for noise-sensitive analogue and digital rails.
- SOT-223
- Board-level power / instruments / communication equipment
- Power management ICs

Product description
Low dropout helps cut system power loss and heat, while the SOT-223 package balances thermal performance with easy assembly. Other output voltages can be combined in the same order, avoiding repeated quotation rounds.
