GENERAL DESCRIPTION
The ADP124/ADP125 are low quiescent current, low dropout
linear regulators. They are designed to operate from an input
voltage between 2.3 V and 5.5 V and to provide up to 500 mA
of output current. The low 130 mV dropout voltage at a 500 mA
load improves efficiency and allows operation over a wide input
voltage range.
The low 210 μA of quiescent current with a 500 mA load makes the
ADP124/ADP125 ideal for battery-operated portable equipment.
The ADP124 is capable of 31 fixed-output voltages from 1.75 V
to 3.3 V. The ADP125 is the adjustable version of the device and
allows the output voltage to be set between 0.8 V and 5.0 V by
an external voltage divider.
The ADP124/ADP125 are specifically designed for stable operation
with tiny 1 F ceramic input and output capacitors to meet the
requirements of high performance, space constrained applications.
The ADP124/ADP125 have an internal soft start that gives a
constant start-up time of 350 s. Short-circuit protection and
thermal overload protection circuits prevent damage in adverse
conditions. The ADP124/ADP125 are available in 8-lead
exposed paddle MSOP and LFCSP packages. When compared
with the standard MSOP and LFCSP packages, the exposed
paddle MSOP and LFCSP packages have lower thermal resistance
(θJA). The lower thermal resistance package allows the ADP124/
ADP125 to meet the needs of a variety of portable applications
while minimizing the rise in junction temperature.
