3 Description

The LP8900 is a dual LDO capable of supplying 200-mA output current per regulator. Designed to meet the requirements of RF and 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 bypass capacitor.

The LP8900 is designed to be stable with space saving ceramic capacitors as small as 0402 case size, enabling a solution size < 4 mm2. Performance is specified for a –40°C to +125°C junction temperature range.

Output voltage options from 1.2 V to 3.6 V are available; for availability, contact your local TI sales office.
