down, the supply current drops to 3.5μA, maximizing
battery life. The internal P-channel MOSFET in the buck
converter and linear regulators turn off to isolate each
input from its output. The output capacitance and load
current determine the rate at which the output voltage
decays. For automatic shutdown and startup, connect
SHDN to IN. Connect SHDN to IN through a resistive
voltage-divider to implement a programmable under-
voltage lockout. Do not leave SHDN floating.
Power-OK (POK)
The open-drain POK output is useful as a simple error
flag, as well as a delayed reset output. POK sinks cur-
rent when any of the three regulated output voltages is
11% below its regulation point. Connect POK to OUT_
through a high-value resistor for a simple error flag indi-
cator. Connect a capacitor from POK to GND to pro-
duce a delayed POK signal (delay set by the RC time
constant). POK is low in shutdown and is high imped-
ance when all three outputs are in regulation.
Thermal-Overload Protection
Thermal-overload protection limits total power dissipation
in the MAX1534. When the junction temperature exceeds
T J = +160 ° C, a thermal sensor turns off the pass transis-
tor, allowing the IC to cool. The thermal sensor turns the
IC on again after the IC ’ s junction temperature cools by
15 ° C, resulting in a pulsed output during continuous
thermal-overload conditions.
Thermal-overload protection is designed to protect the
MAX1534 in the event of fault conditions. For continu-
