DESCRIPTION
The LP8900 is a dual linear regulator capable of
supplying 200 mA 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 bypass 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 TI
sales office.
