LP5904  
Ultra Low Noise, 200 mA Linear Regulator for RF/Analog  
Circuits - Requires No Bypass Capacitor  
General Description  
Key Specifications  
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 280resistor is  
wired from the output to ground pins to quickly discharge out-  
put when the device is disabled (VEN = low).  
Input voltage range  
2.2V to 5.5V  
1.2V to 4.4V  
200 mA  
Output voltage range

95 mV typ.  
Low dropout  
The device is designed to work with a 1.0 μF input and a  
1.0 μF output ceramic capacitor. (No Bypass Capacitor is re-  
quired.)  
Package  
4-Bump micro SMD  
The device is available in a micro SMD package. For other  
package options contact your local TI sales office.  
0.815 mm x 0.815 mm x  
0.600 mm  
(lead free)  
This device is available between 1.2V and 4.4V in 25 mV  
steps. Please contact Texas Instruments Sales for specific  
voltage option needs.  
Applications  
Cellular phones
