The AP7315Q 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 AP7315Q is available with fixed output voltage variants with an enable input to turn it on and off. It is available with output discharge (AP7315DQ) and without (AP7315Q) output discharge function.

With its low power consumption and, line and load transient responses the AP7315Q is well suited for noise sensitive automotive applications.
The AP7315Q is qualified to AEC-Q100 Grade 1 in SOT25 and is Automotive Compliant supporting PPAPs.
