DESCRIPTION

The μ PD121WxxA series is general-purpose CMOS regulators which have 1.5 A output current capacity. These products are suitable for power supply of large-scale ASICs etc. By ON/OFF function, the power consumption can be kept low level at the time of off-state. This series of regulator has 3 fixed output voltage type 1.8 V, 2.5 V, 3.3 V, and adjustable output voltage type (1.8 to 3.3 V).

FEATURES
