R1180x Series
Low Supply Current 150mA LDO
The R1180x Series are CMOS-based LDO regulators featuring 150mA output. R1180x’s typical ultra low supply current of 1μA makes
it ideal for use in power supplies systems with the sleep mode on. The version that reduced supply current to the lowest possible
level by eliminating the CE pin is also available. Ceramic capacitors can be used.
