DESCRIPTION
The APE8838 is a high accurately, low noise, high
ripple rejection ratio, low dropout, dual 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 APE8838 has the soft start function to suppress
the inrush current. The current limit is over 250mA per
channel and also operates as a short protection for the
output current limiter. The output voltage for each regulator
is set independently by metal trimming.
The APE8838 is 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 SOT-26 and DFN 2x2
packages.
