Applications
General Description
The AP6401 series are highly accurate, dual, low
noise, CMOS LDO voltage regulators with enable
function. The EN function allows the output of each
regulator to be turned off independently, resulting in
greatly reduced power consumption. The AP6401
series have the soft start function to suppress the
inrush current. The current limiters' fold back circuit
(it happens when over 350mA per channel) also
operates as a short protection for the output current
limiter. The output voltage for each regulator is set
independently by metal trimming. It’s also available
to offer the honors other types of VOUT between
+1.2V ~+3.9V except the options shown on ordering
information.
This series are fully compatible with low ESR
ceramic capacitors, reducing cost and improving
output stability. This high level output stability is
maintained even during frequent load fluctuations,
due to the excellent transient response performance
and high PSRR achieved across a broad range of
frequency. It is available in the SOT26, UFN-6 and
DFN-6 ‘chip-scaled’ package.
