loads. The MAX1534 does not suffer from these prob-
lems. While a PNP-based regulator has dropout voltage
that is independent of the load, a P-channel MOSFET ’ s
dropout voltage is proportional to load current, provid-
ing for low dropout voltage at heavy loads and
extremely low dropout voltage at lighter loads.
Current Limit
The MAX1534 contain two independent current limiters,
one for each linear regulator, which monitor and control
the pass transistor ’ s gate voltage, limiting the guaran-
teed maximum output current to 160mA minimum. The
output can be shorted to ground for an indefinite time
without damaging the part.
Low-Noise Operation
An external 0.01μF bypass capacitor at BP, in conjunc-
tion with an internal resistor, creates a lowpass filter,
reducing the LDO output voltage noise.
Shutdown ( SHDN )
The MAX1534 ’ s accurate SHDN input can be used as a
low-battery voltage detector. Drive SHDN above the 1V
input rising-edge trip level to start up the MAX1534.
base drive, which reduces quiescent current signifi-
cantly. PNP-based regulators waste considerable cur-
rent in dropout when the pass transistor saturates, and
they also use high base-drive currents under large
The 100mV SHDN input hysteresis prevents the
MAX1534 from oscillating between startup and shut-
down. Drive SHDN low to shut down the MAX1534 ’ s
buck converter and linear regulators. When in shut-
