RT9094A Datasheet | Richtek

Description The RT9094A is a very low dropout linear regulator which operates f rom input voltage as low as 0.8V. The device is capable of supplying 2A of output current with a typical dropout voltage of only 100m V. A VBIAS supply is required to run the internal ref erence and LDO circuitry while output current es directly f rom the VIN supply f or high ef f iciency regulation. Userprogrammable soft-start limits the input inrush current and minimizes stress on the input power. The enable input and power good output allow easy sequencing with external regulators. This plete f lexibility provides an eas y -t o-us e ro bust p ower management solution f or a wide variety of applications. The RT9094A is stable with output capacitor greater than or equal to 2.2F. A precise ref erence and error amplif ier deliver 1% accuracy over load, line and temperature. Overcurrent limit and over-temperature protection are also included. The RT9094A is available in the WDFN-10L 3x3 package. The remended ambient temperature range is - 40C to 85C. 2 Features - Ultra low VIN Range: 0.8V to 5.5V - VBIAS Voltage Range: 2.7V to 5.5V - VOUT Voltage Range: 0.8V to 3.6V - Low Dropout: 100m V Typical. at 2A, VBIAS = 5V - 1% Accuracy Over Line/Load/Temperature - PGOOD Indicator for Easy Sequence Control - Programmable Soft-Start Provides Linear Voltage Startup - Stable with Any Output Capacitor  2.2F - Overcurrent and Over-Temperature Protection 3 Applications - PCs, Servers, Modems, and Set-Top-Boxes - FPGA Applications - DSP Core and I/O Voltages - Instrumentation - Post-Regulation Applications - Applications With Sequencing Requirements 4 Simplified Application Circuit VIN VBIAS CBIAS CSS RT9094A VIN PGOOD EN VBIAS VOUT FB SS RPGOOD R1 VOUT COUT R2 Copyright © 2024 Richtek Technology Corporation.
