LP5907  
Ultra Low-Noise, 250 mA Linear Regulator for RF/Analog  
Circuits - Requires No Bypass Capacitor  
General Description  
Key Specifications  
The LP5907 is a linear regulator capable of supplying 250 mA  
output current. Designed to meet the requirements of RF/  
Analog circuits, the LP5907 device provides low noise, high  
PSRR, low quiescent current, and low line/load transient re-  
sponse figures. Using new innovative design techniques the  
LP5907 offers class-leading noise performance without a  
noise bypass capacitor and the ability for remote output ca-  
pacitor placement.  
Input voltage range  
2.2V to 5.5V  
1.2V to 4.5V  
250 mA  
Output voltage range  
Output current

Startup time  
<10 μVRMS  
82 dB at 1kHz  
± 2%  
<1μA  
12 μA  
80 μs  
120 mV typ.  
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.)  
Low dropout  
The device is available in an ultra-thin micro SMD package.  
This device is available between 1.2V and 4.5V in 25 mV  
steps. Please contact Texas Instruments Sales for specific  
voltage option needs.  
Package  
4-Bump ultra-thin micro SMD  
0.35 mm pitch  
0.65 mm x 0.65 mm x  
0.40 mm  
(lead free)  
Features

No Noise Bypass Capacitor Required  
Applications  
Cellular phones  
Remote Output Capacitor Placement  
PDA handsets  
Thermal-overload and short-circuit protection  
−40°C to +125°C junction temperature range for operation  
Wireless LAN devices
