    Products Detail

    The RT9053A is a high-performance, 400mA LDO regulator with ultra-low dropout. It features ultra-low quiescent current of 35μA (typical) to prolong battery life, compatibility with low ESR ceramic capacitors to reduce board space, and consumes only 0.7μA in shutdown mode. The device offers adjustable output voltage down to 0.8V, wide operating voltage range (2.2V to 5.5V), low dropout voltage (230mV at 400mA), ultra-fast line/load transient response, current-limit protection, and over-temperature protection. It requires only 1μF output capacitor for stability and is available in SOT-23-5 and WDFN-6L 2x2 packages.

    Key Features

    • Adjustable Output Voltage Down to 0.8V, Wide Operating Voltage Ranges: 2.2V to 5.5V, Low Dropout: 230mV at 400mA, Ultra-Fast Response in Line/Load Transient, Current-Limit Protection, Over-Temperature Protection, Output Only 1μF Capacitor Required for Stability, Ultra-Low Quiescent Current: 35μA (typical), Compatible with Low ESR Ceramic Capacitors, Shutdown Current: 0.7μA (typical)
