The MAX15029/MAX15030 low-dropout linear regula-
tors operate from input voltages as low as 1.425V and
deliver up to 500mA of continuous output current with a
typical dropout voltage of only 40mV. The output volt-
age is adjustable from 0.5V to V
over load and line variations, from -40°C to +125°C.
The MAX15030 features a BIAS input of 3V to 5.5V from
an always-on power supply. The BIAS input current is
reduced down to less than 2µA during the shutdown.
These regulators use small, 1µF ceramic input capaci-
tors and 2.2µF ceramic output capacitors to deliver
500mA output current. High bandwidth provides excel-
lent transient response and limits the output voltage devi-
ation to 10mV for a 100mA to 500mA load step, with only
a 2.2µF ceramic output capacitor, and the voltage devia-
tions can be reduced further by increasing the output
capacitor.
These devices offer a logic-controlled shutdown input
to reduce input current (I
than 5.5µA in standby mode. Other features include a
soft-start to reduce inrush current, short-circuit protec-
tion, and thermal-overload protection.
The MAX15030 features a BIAS input allowing a sec-
ondary supply to keep the LDO’s internal circuitry alive
if the voltage on IN goes to 0. Both devices are fully
specified from -40°C to +125°C and are available in a
10-pin thermally enhanced TDFN package (3mm x
3mm) that includes an exposed pad for optimal power
dissipation. For a 1A version of these LDOs, refer to the
MAX15027/MAX15028 data sheet.
