Linear Regulators
(LDO)
AKM’s LDO series realizes high ripple rejection performance with low noise characteristics using AKM’s circuit technology that has been developed with many years’ experience in its market and a silicon monolithic bipolar architecture.
The LDO series is suitable for a low-noise power supply system such as Automotive Infotainments, Image Sensors and Measurement Instruments.
Low-noise LDO with high precision monitoring and self-diagnostic functions for ADAS and autonomous driving systems
AP1161ABN / AP1163ABN
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).
A Small Package of Low Output Noise, High Performance LDO Regulator, and Active Noise Filter
AP115xAEU series
(AP1150AEUXX, AP1151AEU, AP1152AEUXX, AP1158AEU)
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).
A Low Output Noise, High Performance LDO Regulator, and Active Noise Filter
AP115xADS series
(AP1150ADSXX, AP1151ADS, AP1152ADSXX, AP1158ADS)
AKM has launched low-output noise LDO regulators, and an active noise filter, the AP115xADS series.
Low-noise LDO regulator with output voltage adjustability, supporting 1A output current
AP1155ADL
● 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.
