AKM has launched low-noise LDO regulators, the AP1161AB and the AP1163ABN, which meet functional safety *1.

*1:  ISO26262 requirements for functional safety requirements can easily be achieved when utilized these devices.

● High precision monitoring of output voltage

The AP1161ABN/AP1163ABN monitors the output voltage to detect undervoltage and overvoltage status.  If the status is met, a flag signal is sent to the MCU.

● Self-diagnostic function

Failure of the monitoring function can be detected by inputting, "H", signal to the DIAG pin.  By incorporating this function into the system, periodic fault detection during operation is available.

● Low-output noise

The AP1161ABC/1163ABC achieves output noise of 180 nV/√Hz, (at 10kHz), and PSRR of 78dB, (at 1kHz) *2.  This exceeds the requirements of in-vehicle communications for severe noise and RF power supply requirements.

*2:  PSRR of the AP1163ABN.  The AP1161ABN has a PSRR of 76 dB, (at 1 kHz).

AKM has launched low-output noise LDO regulators, and an active noise filter, the AP115xAEU series, housed in a small package.

The AP115xAEU series achieves miniaturization to 1.8 × 2.2 × 0.6 mm while maintaining low output noise performance of AP1150ADSXX, AP1151ADS, AP1152ADUXX, AP1158ADS. In addition, the AP115xAEU has significantly improved heat dissipation by adopting a package with a heat dissipation pad on the bottom surface, (Power Dissipation is 1.6 times to 3 times higher than the previous series).

AKM has launched low-output noise LDO regulators, and an active noise filter, the AP115xADS series.

● Low Noise

The AP1155ADL realizes high ripple rejection with low noise characteristics by adopting silicon monolithic bipolar architecture.

● Corresponded to High Power Applications

The AP1155ADL is capable of supplying 1A output current stably. It is housed in an HSOP-8 package with exposed-pad. Therefore, it has high heat radiation performance and is suitable for high power applications.

● Wide Output Voltage can be set

A suitable output voltage for the application can be selected in a range from 1.3V to 13.5V by external resistors.
