Ricoh R1173x Series Super Low On Resistance/Low Voltage LDO Datasheet
The R1173x Series are CMOS-based positive voltage regulator ICs designed for applications requiring large currents at small dropout voltages. Key features include a typical load regulation of -3mV at 1A, an output current capability of 1A, and the ability to set minimum input voltages as low as 1.4V with adjustable output voltages starting from 0.8V.
The series is available in SOT-89-5, HSON-6, and HSOP-6J packages to support high-density mounting. The ICs incorporate built-in thermal shutdown and current limit circuits for protection, along with a chip enable circuit that allows for an ultra-low consumption standby mode.
