Description

The EC8841 series is a positive voltage regulator

with high accuracy output voltage and ultra-low

quiescent current which is typically 1.0

μA. The

device is ideal for battery powered handheld

equipments which require low quiescent current.

The EC8841 contains a bandgap voltage reference,

an error amplifier, a P-channel pass transistor, and a

resistor-divider for setting output voltage. The output

voltage is fixed with high accuracy by advanced

trimming technology.

The EC8841 has been designed to be used with low

cost ceramic capacitors and requires a minimum

output capacitor of

1.0μF. The devices are available

in SOT23-3/5, SOT89 and TO92 packages
