1 / 17 page  RTQ2521 ® DSQ2521-01 May 2019 www.richtek.com 1 Copyright 2019 Richtek Technology Corporation. All rights reserved. is a registered trademark of Richtek Technology Corporation. © General Description The RTQ2521 is a high-current (1.2A), low-noise (6 μVrms), high accuracy (1% over line, load, and temperature), low- dropout linear regulator (LDO) capable of sourcing 1.2A with extremely low dropout (max. 75mV). The device supports single input supply voltage as low to 1.1V that makes it easy to use. The low noise, high PSRR and high output current capability makes the RTQ2521 ideal to power noise-sensitive devices such as analog-to-digital converters (ADCs), digital-to- analog converters (DACs), and RF components. With very high accuracy, remote sensing, and soft-start capabilities to reduce inrush current, the RTQ2521 is ideal for powering digital loads such as FPGAs, DSPs, and ASICs. The external enable control and power good indicator function makes the sequence control easier. The output noise immunity is enhanced by adding external bypass capacitor on NR/SS pin. The device is fully specified over the temperature range of TJ = −40°C to 125°C and is offered in the WDFN-8EL 3x3 package. Features Input Voltage Range : 1.1V to 6.5V Output Voltage Range : 0.8V to 5.5V Accurate Output Voltage Accuracy (1%) Over Line, Load and Temperature Ultra High PSRR : 38dB at 500kHz Excellent Noise Immunity 6 μμμμμVRMS at 0.8V Output Ultra Low Dropout Voltage : 75mV at 1.2A Enable Control Programmable Soft-Start Output Stable with a 4.7 μμμμμF or Larger Ceramic Output Capacitor Support Power-Good Indicator Function RoHS Compliant and Halogen Free Applications Portable Electronic Device Wireless Infrastructure : SerDes, FPGA, DSP RF, IF Components : VCO, ADC, DAC, LVDS 1.2A, 6.5V, Ultra Low Noise, Ultra Low Dropout Linear Regulator Marking Information Ordering Information Pin Configuration (TOP VIEW) WDFN-8EL 3x3 VOUT FB PGOOD VIN EN NR/SS NC GND 7 6 5 1 2 3 4 8 9 Note : Richtek products are : RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020. Suitable for use in SnPb or Pb-free soldering processes.
