RTQ2531A  
500mA, 5.5V, Low Noise Low Dropout Regulator  
Features  
General Description  
⚫ Input Voltage Range : 1.7V to 5.5V  
⚫ Output Voltage Range : 0.6V to 5.3V  
⚫ Accurate Voltage Reference  
The RTQ2531A is a low-noise, high accuracy, low-  
dropout linear regulator (LDO), and is capable of  
sourcing 500mA. The device supports single input  
supply voltage as low to 1.7V, which makes it easy to  
use.  
0.6V 1.5%, Over −40C to 125C  
⚫ Ultra High PSRR : 48dB at 500kHz  
⚫ Excellent Noise Immunity : 25V  
RMS  
The RTQ2531A is designed with high PSRR and low  
noise, which can meet the requirements of noise-  
sensitive applications such as RF, PLL, Clocking and  
analog circuits. The regulator control circuitry includes a  
programmable soft-start circuit and short circuit, reverse  
current, and over-temperature protection. Other  
features include an enable input and a power-OK output.  
The device is fully specified over the temperature range  
⚫ Ultra Low Dropout Voltage : 150mV at 500mA  
⚫ Enable Control  
⚫ Short-Circuit Protection  
⚫ Output-to-Input Reverse Current Protection  
⚫ Support Power-OK Output Indicator Function  
⚫ RoHS Compliant and Halogen Free  
Applications  
⚫ Portable Electronic Device  
of T = −40°C to 125°C and is offered in a WDFN-8SL  
J
2x2 package.  
⚫ Optical Modules  
⚫ Camera Modules  
Ordering Information  
⚫ PLL/Synthesizer, Clocking Sensors  
⚫ Medium-Current, Noise Sensitive Application
