The RT9187GSP is a high-performance linear voltage regulator designed for applications requiring low dropout voltage and high power supply rejection ratio (PSRR). It supports an output current of up to 1A and operates within a voltage range of 2.5V to 5.5V. The device features an ultra-low dropout voltage of 240mV at 1A, making it suitable for battery-powered and portable RF applications. The regulator includes a noise reduction pin for minimizing output noise, which is particularly beneficial in RF applications. In shutdown mode, it consumes less than 0.1OºA, contributing to extended battery life. The RT9187GSP is compatible with low-ESR ceramic capacitors, allowing for reduced board space requirements. Protection features include current limiting and thermal shutdown, ensuring safe operation under various conditions. The device is available in two package types: VDFN-8L 3x3 and SOP-8 (Exposed Pad), and is RoHS compliant. This regulator is ideal for use in CDMA/GSM cellular handsets, battery-powered equipment, and portable information appliances.
