Product Description
DiodesZetex AP2138N-3.3TRG1 is a 5-Channel Low Noise Low Dropout (LDO) linear voltage regulator designed for use in electronic circuits requiring a stable 3.3V output voltage with up to 250mA load current. The device is delivered in a space-saving SOT-23 3-pin package measuring just 3.02mm by 1.7mm by 1.3mm, making it suitable for compact PCB layouts in various industrial, commercial, and consumer electronics applications.
This regulator features a low noise output, making it ideal for use in sensitive analog and RF circuits where minimal interference is critical. The LDO design allows operation with a low input-to-output voltage differential, enabling efficient power regulation with minimal heat dissipation.
Operating input voltage ranges from 2.5V up to a maximum of 6.6V, giving design flexibility for different power sources. The regulator supports operation across a wide temperature range from -40°C to 85°C, suitable for demanding environmental conditions in automotive, industrial, and instrumentation uses.
Additional electrical performance highlights include a line regulation of 18mV and load regulation of 40mV, ensuring stable output voltage under varying load and supply conditions. The low quiescent current of 1.5μA optimizes battery-powered device efficiency, contributing to longer device operation times.
The product is RoHS compliant, aligning with international environmental regulations for reduced hazardous substances. This makes it suitable for inclusion in certified electronic products.
