Model KA78R12CTU
Description LDO（Low voltage drop linear voltage regulator, Fairchild Semiconductor # # # LDO (low voltage drop) linear voltage regulator - Fairchild Semiconductor's low voltage drop or LDO is a linear voltage regulator. We have multiple series of linear regulators. LDO regulators can operate when the input-output differential voltage is low. LDO voltage regulators can provide fast transient response, wide input voltage range, low static current, low noise, and high PSRR.
