for Operation DESCRIPTION
The LP5904 is a linear regulator capable of supplying
200 mA output current. Designed to meet the
requirements of RF/ Analog circuits, the LP5904
device provides low noise, high PSRR, low quiescent
current, and low line transient response figures. Using
new innovative design techniques the LP5904 offers
class-leading device noise performance without a
noise bypass capacitor and the ability for remote
output capacitor placement. An active pulldown circuit
with a 280О© resistor is wired from the output to
ground pins to quickly discharge output when the
device is disabled (VEN = low). APPLICATIONS Cellular Phones
