The RP109K291D-TR is a low noise, 150mA linear voltage regulator from the RP109x series by Lingto Electronic Limited. It features a typical supply current of 50µA and a standby mode current of 0.1µA, making it suitable for battery-powered applications. The device operates with a dropout voltage of 0.25V at 150mA output current and provides a ripple rejection of 75dB at 1kHz. The output voltage accuracy is ±1.0%, and it supports an output voltage range from 0.8V to 3.6V in 0.1V steps. The RP109K291D-TR is designed for excellent line and load transient response, making it ideal for portable communication equipment and other handheld devices. It is available in multiple packages, including the ultra-compact DFN(PL)0808-4, which allows for space-saving designs. The device also includes built-in fold-back protection and is recommended to be used with ceramic capacitors of 0.1µF or more. The input voltage range is from 1.4V to 5.25V, providing flexibility for various applications.
