Product Introduction
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 μF 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 μs. 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.
