New compact, low-noise LDO regulators from Toshiba
Toshiba has introduced the TCR5FM series of 35 LDO regulators, which help stabilise the DC power line for small devices, such as smartphones and wearables. The LDO regulators help address the challenge engineers face when designing battery-powered devices to switch from low-power mode to high-speed processing, thereby maximising performance and battery life. This mode switching can inherently destabilise the DC power line, requiring LDO regulators with fast load transient response.
ROHM develops an ultra-compact MOSFET ideal for fast charging
ROHM has developed a 30V N-channel MOSFET — AW2K21 — in a common-source configuration that achieves an industry-leading ON-resistance of 2.0mΩ (typ.) in a compact 2.0mm × 2.0mm package.
AKM launches new series of power management ICs for energy harvesting
Asahi Kasei Microdevices (AKM) has developed the AP4413, a new series of ultra-low current power management ICs (PMICs) ideal for battery charging systems used in energy harvesting applications. The AP4413 series enables efficient battery charging while consuming an extremely low current of 52 nA and features four variants with voltage threshold characteristics matching several common rechargeable battery types. The AP4413 comes in a tiny 3.0 × 3.0 × 0.37 mm HXQFN package and has been in mass production since February of 2025.
