AP7315 Low Dropout Regulator

Diodes’ AP7315 low dropout regulator offers lower operation down to 1.7 V supporting operation over an entire range of Li-on battery cells

Image of Diodes' AP7315 Low Dropout RegulatorDiodes' AP7315 is a low dropout regulator with high output-voltage accuracy, low RDS(ON), high PSRR, low output noise, and low quiescent current. This regulator is based on a CMOS process.

The AP7315 includes a voltage reference, error amplifier, current limit circuit, and an enable pin. With the integrated resistor network, fixed output voltage versions can be delivered. With its low power consumption and line and load transient response, the AP7315 is well suited for low power handheld communication equipment.

The AP7315 is packaged in the industry-standard SOT23, SOT25, and X2-DFN1010-4 packages and allows for the smallest footprint and dense PCB layout.
