Detailed Description
The MAX8530/MAX8531 are low-power, low-dropout,
low-quiescent current linear regulators with reset
designed primarily for battery-powered applications.
For preset output voltages, refer to the Output Voltage
Selector Guide . Other combinations between 1.5V and
3.3V are available in 50mV increments. This device
supplies loads up to 200mA for OUT1 and 150mA for
OUT2. The MAX8530/MAX8531 consist of a 1.25V ref-
erence, error amplifiers, P-channel pass transistors,
reset block, and internal feedback voltage-dividers.
The 1.25V bandgap reference is connected to the error
amplifier’s inverting input. The error amplifier compares
this reference with the feedback voltage and amplifies
the difference. If the feedback voltage is lower than the
reference voltage, the pass-transistor gate is pulled
lower, allowing more current to pass to the output and
increasing the output voltage. If the feedback voltage is
too high, the pass-transistor gate is pulled up, allowing
less current to pass to the output. The output voltage is
fed back through an internal resistor voltage-divider
connected to the OUT_ pin.
RESET
The reset circuit is active at power-up and power-down.
RESET is held low at power-up. The reset timing starts
once the OUT1 voltage reaches 87% (typ) of its regula-
tion voltage. The RESET signal goes high 200ms (typ)
after the OUT1 voltage reaches 87% (typ) of its regulation
voltage. At power-off, RESET goes low when the OUT1
voltage is below 87% (typ) of its regulation voltage.
