RTQ2502A
Overview
The RTQ2502A is a high-current (2A), low-noise (6μVrms), high accuracy (1% over line, load, and temperature), lowdropout linear regulator (LDO) capable of sourcing 2A with extremely low dropout (max. 125mV). The device output voltage is pin-selectable (up to 3.95V) using a PCB layout without the need of external resistors, thus reducing overall component count.
- Input Voltage Range : 1.1V to 6.5V
- Two Output Voltage Modes 0.8 V to 5.5V (Set by a Resistive Divider) 0.8 V to 3.95V (Set via PCB Layout, No External Resistor Required)
- Accurate Output Voltage Accuracy (1%) Over Line, Load and Temperature
- Ultra High PSRR : 40dB at 500kHz
- Excellent Noise Immunity 6μVRMS at 0.8V Output
- Ultra Low Dropout Voltage : 125mV at 2A
- Enable Control
- Programmable Soft-Start Output
- Stable with a 22μF or Larger Ceramic Output Capacitor
- Support Power-Good Indicator Function
