LP5907 250-mA, Ultra-Low-Noise, Low-IQ LDO  
1 Features  
3 Description  
The LP5907 is a low-noise LDO that can supply up to  
1
Input voltage range: 2.2 V to 5.5 V  
Output voltage range: 1.2 V to 4.5 V  
250 mA output current. Designed to meet the  
requirements of RF and analog circuits, the LP5907  
device provides low noise, high PSRR, low quiescent  
current, and low line or load transient response  
figures. Using new innovative design techniques, the  
LP5907 offers class-leading noise performance  
without a noise bypass capacitor and the ability for  
remote output capacitor placement.  
Stable with 1-µF ceramic input and output  
capacitors  
No noise bypass capacitor required  
Remote output capacitor placement  
Thermal-overload and short-circuit protection  
–40°C to 125°C operating junction temperature  
Low output voltage noise: < 6.5 µVRMS  
PSRR: 82 dB at 1 kHz  
The device is designed to work with a 1-µF input and  
a 1-µF output ceramic capacitor (no separate noise  
bypass capacitor is required).  
Output voltage tolerance: ±2%  
This device is available with fixed output voltages  
from 1.2 V to 4.5 V in 25-mV steps. Contact Texas  
Instruments Sales for specific voltage option needs.  
Very low IQ (enabled): 12 µA  
Low dropout: 120 mV (typical)
