RICOH R1172x Series 1A LDO handbook

Update: 30 September, 2023

R1172x Series 1A LDO is a CMOS-based linear regulator featuring 1A output. CMOS process provides both high output current and low supply current. The dropout voltage is significantly lower than bipolar regulators. R1172x handles low voltage with an input voltage from 1.4V and output voltage from 0.8V. Accordingly, the device supports highly integrated, low voltage-driven LSI as a rear stage of the DC/DC converter. The CE pin can switch the regulator into standby mode. In addition to a fold-back protection circuit built into conventional LDO regulators, R1172x has a thermal shutdown circuit and inrush current limit circuit. Ceramic capacitors can be used
