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 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 an 8-lead

exposed paddle MSOP package. When compared with the

standard MSOP package, the exposed paddle MSOP package

has lower thermal resistance (θ_JA). 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.

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.
