The RT9093/RT9093N is a low-dropout (LDO) linear regulator capable of operating with input voltages ranging from 1.2V to 5.5V and supplying up to 300mA of output current. The output voltage is designed to operate in two modes for different purposes. In the adjustable mode, the RT9093/RT9093N output voltage can be set from 0.8V to 5V. In the fixed mode, the output voltage is available from 0.8V to 3.45V without the need for an external resistive voltage divider, saving on the bill of materials (BOM) costs in conditions where the PCB area is limited.This device implements the EN pin for system sequencing. It also integrates input undervoltage-lockout (UVLO), overcurrent protection (OCP), and over-temperature protection (OTP) to prevent fault conditions.The RT9093/RT9093N is available in the TSOT-23-5 package with both fixed and adjustable output voltage options facilitating easy use in various applications. It is also offered in the ZQFN-4L 1x1 package without an external resistive voltage divider. The device is fully specified for operation over the temperature range of TJ = -40°C to 125°C.
