LDO Regulator Application Note

Low Supply Current Type and High-performance Type

Ricoh LDO regulators can be classified in three types by performance, a Low Supply Current Type, a High-performance Type, and the Standard Type of average specifications. The Low Supply Current Type gives priority over the performance by the reduction of the supply current during operation. On the other hand, the High-performance Type gives priority to the performance during operation (low noise and fast transient response) over the supply current. A standard type is a product which is balanced between both performance and supply current. Ricoh is preparing many variations, in order to respond to a user's request.

  Supply Current Transient Response Ripple Rejection
Low Supply Current Type Ultra low Slow Low
High-performance Type High Fast High
