The RP100K191B-TR is a CMOS-based linear voltage regulator IC designed for applications requiring high output voltage accuracy and low noise. It provides a fixed output voltage of 1.9V with a maximum output current of 200mA. The device features a low supply current of approximately 18OºA and a standby current of just 0.1OºA, making it suitable for battery-powered devices. The dropout voltage is low at 0.13V under typical conditions, and it offers a ripple rejection of 75dB at 1kHz. This regulator is packaged in a compact DFN(PL)1612-4 format, allowing for high-density mounting on circuit boards. It operates within an input voltage range of 1.7V to 5.25V and supports output voltage settings in 0.1V increments from 1.2V to 3.3V. The device includes built-in fold-back protection and is recommended for use with ceramic capacitors of 1.0OºF or more. Applications include power supplies for portable communication equipment and various battery-operated devices.
