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.
