The ADPL40502 is a low noise, low dropout (LDO) linear regulator that operates from 2.2V to 5.5V and provides up to 200mA of output current. The low 150mV dropout voltage at 200mA load improves efficiency and allows operation over a wide input voltage range.
Using an innovative circuit topology, the ADPL40502 achieves low noise performance without the necessity of a bypass capacitor, making the device ideal for noise sensitive analog and RF applications. The ADPL40502 also achieves low noise performance without compromising the power supply rejection ratio (PSRR) or transient line and load performance. The low 290μA of operating supply current at 200mA load makes the ADPL40502 suitable for battery-operated portable equipment.
The ADPL40502 includes an internal pull-down resistor on the EN input.
The ADPL40502 is specifically designed for stable operation with tiny 1μF, ±30% ceramic input and output capacitors to meet the requirements of high performance, space constrained applications.
The ADPL40502 is capable of 7 fixed output voltage options, ranging from 1.2V to 3.3V.
Short-circuit and thermal overload protection circuits prevent damage in adverse conditions. The ADPL40502 is available in tiny 5-Lead, TSOT and 6-Lead, 2mm x 2mm LFCSP for the smallest footprint solution to meet a variety of portable power application requirements.
