Nisshinbo Micro Devices Inc. Voltage Regulators - Linear, Low Drop Out (LDO) Regulators RP117K501D-TR

The RP117K501D-TR is a negative voltage low dropout (LDO) regulator designed to provide high ripple rejection and low output noise, making it suitable for noise-sensitive applications. It operates within an input voltage range of -10.0 V to -2.5 V and can deliver an output voltage between -5.5 V and -1.0 V, with a maximum output current of 100 mA. The device features a typical ripple rejection rate of 80 dB at 1 kHz and an output noise of 16 OºVrms, which is beneficial for applications such as sensors, audio devices, and measuring instruments. The RP117K501D-TR requires only one capacitor for each input and output, simplifying the design and saving board space. It is available in compact DFN(PL)1212-6 and SC-88A packages. Additional protective features include thermal shutdown protection, short-circuit protection, and an auto-discharge function that quickly lowers the output voltage to 0 V when transitioning to standby mode. This product is suitable for various applications, including digital-to-analog converters (DACs), analog-to-digital converters (ADCs), and liquid crystal panels.
