Low-Dropout Regulators (LDO Regulators)

Toshiba offers a wide choice of LDO regulators in packages ranging from general-purpose to ultra-compact that are suitable for high-performance requirements, such as low noise, high ripple compressibility (PSRR), high output current stability (load transient response), and low current consumption, which are particularly required for state-of-the-art analog circuits. The newly developed new-generation process also significantly improves dropout characteristics and provides a high-efficiency linear regulator solution.
