Ricoh Electronic Devices Company RP124 Low Supply Current LDO Regulators

Ricoh RP124 Low Supply Current LDO Regulators with a battery monitor offers an ultra-low current consumption of only 0.3μA at no-load. This ultra-low consumption extends the life of battery powered devices. The RP124 requires three external capacitors, making it ideal for space-saving mounting in smaller packages. The RP124 uses a built-in resistor divider and voltage follower as a buffer instead of using an external resistor divider + MOSFET connected to an A/D Converter. This makes the device have an advantage, creating this circuit with a much lower current flow to ground and the output is compatible with the input impedance of the A/D converter.
