RTQ2532N Datasheet | Richtek

Description The RTQ2532N is a high-current (2A), low-noise (6.8VRMS), high accuracy (1% over line, load, and temperature), low-dropout linear regulator (LDO) capable of sourcing 2A with extremely low dropout (max. 125m V). The device output voltage is pinselectable (up to 3.95V) using a PCB layout without the need of external resistors, thus reducing overall ponent count. Designers can achieve higher output voltage with the use of external resistor divider. 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 RTQ2532N ideal to power noisesensitive devices such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and RF ponents. With very high accuracy, remote sensing, and soft-start capabilities to reduce inrush current, the RTQ2532N is ideal for powering digital loads such as FPGAs, DSPs, and ASICs. The external enable control and power good indicator function makes the control sequence easier. The output noise immunity is enhanced by adding external bypass capacitor on the NR/SS pin. The device is fully specified over the temperature range of TJ = - 40C to 125C and is offered in a VQFN-20L 3.5x3.5 package. 2 Ordering Information Pin 1 Orientation (2): Quadrant 2, Follow EIA-481 (Empty means Pin1 orientation is Quadrant 1) Package Type QV: VQFN-20L 3.5x3.5 (V-Type) Lead Plating System G: Richtek Green Policy pliant Note: Richtek products are Richtek Green Policy pliant and patible with the current requirements of IPC/JEDEC J-STD-020. 3 Features - 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 - High PSRR : 40d B at 500k Hz - Noise Immunity - 6.8VRMS at 0.8V Output - 10VRMS at 3.3V Output - Dropout Voltage : 125m V at 2A - Enable...
