50mA Ultra-Low Quiescent Current LDO
Linear Regulator
EC8841
Description
The EC8841 series is a positive voltage regulator
with high accuracy output voltage and ultra-low
quiescent current which is typically 1.0μA. 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
