RP108J Series Low Voltage 3A LDO Regulator with Ext. VOUT Adjustable
The Ricoh RP108J Series are CMOS-based LDO regulators featuring a 3A output current and low on-resistance. The CMOS process provides both large output current and low supply current, with a typical standby current of 350pA. The device handles low voltage with an input voltage range from 1.6V to 5.25V and an output voltage range from 0.8V to 4.2V. The RP108J081x model allows for adjustable output voltage using an external resistor.
In addition to standard protection features like fold-back protection and thermal shutdown, the RP108J includes a reverse current protection circuit and a constant slope circuit for soft start. The constant slope circuit prevents inrush current and misoperation of devices, making it effective for large current products. Ceramic capacitors can be used for the output.
