Nisshinbo Micro Devices Inc. RP106K071D5-TR

The RP106x Series are low voltage 400mA voltage regulator. These ICs had been further improved of low-voltage capability compared with previous low-voltage product. The input voltage is as low as Min. 1.0V and the output voltage can be set from 0.7V. The output voltage accuracy has been improved to ±0.8% and due to a built-in transistor with low on-resistance of 0.55Ω (at Vour = 1.5V). Each of these ICs consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, and a current limit circuits for over-current for the destruction prevention by the over-current. The CE pin can switch the regulator to standby mode. In addition to SOT-23-5 and SC-88A packages, a 0.69mm square WLCSP-4-P5 package and a 1.2mm square DFN(PL)1212-6 are also available.
