The LP8900 is a dual linear regulator capable of supplying 200mA output current per regulator. Designed to meet the requirements of RF/Analog circuits, the LP8900 provides low device noise, High PSRR, low quiescent current and superior line transient response figures. Using new innovative design techniques the LP8900 offers class-leading device noise performance without a noise by- pass capacitor. The LP8900 is designed to be stable with space saving ceramic capacitors as small as 0402 case size, enabling a solution size <4mm 2. Performance is specified for a -40°C to 125°C junction temperature range. Output voltage options are available between 1.2V and 3.6V, for availability please contact your local NSC sales office.
