Applications
The AP6203B is a 4-Low (Low-dropout, Low
-quiescent Current, Low-noise, Low-cost) linear
regulator with ON/OFF control and AP6203B can
discharge output capacitor charge fast. The device
operates in the input voltage range from +2.2V to
+7.0V and delivers 300mA output current.
The high-accuracy output voltage is preset at an
internally trimmed voltage 1.2V, 1.5V, 1.8V, 2.5V,
2.8V, 3.0V or 3.3V. Other output voltages can be
mask-optioned from 1.2V to 5.0V with 100mV
increment, except the AP6203B-LL which has 2.85V
output voltage.
The AP6203B consists of a 1.0V reference compare
amplifier, a P-channel pass transistor, and an
enable/disable logic circuit. Other features include
soft start function, short-circuit protection, and
thermal shutdown protection.
The AP6203B is also compatible with low ESR
ceramic capacitors which give added output stability.
This stability can be maintained even during load
fluctuations due to the excellent transient response
of the chip. The AP6203B devices are available in
SOT-23-5 and UFN-6 packages.
