RT9193-15GB-JSM

The RT9193 series are high-accuracy, low-noise, fast-response LDO linear regulators fabricated using CMOS process technology. These regulators integrate a built-in fixed reference voltage, error correction circuit, current limiting circuit, phase compensation circuit, and a low on-resistance MOSFET, achieving high ripple rejection, low output noise, and fast-response low-dropout performance. The RT9193 series is compatible with ceramic capacitors that are smaller than coin-type capacitors, and does not require a 0.1μF bypass capacitor, enabling further space savings and cost reduction. With high-accuracy output regulation and fast transient response to handle load current fluctuations, the series is particularly well-suited for handheld devices and RF products. By controlling the CE pin on the chip, the output can be shut down. The quiescent current after shutdown is only 0.1μA (typ.), significantly reducing power consumption.
