Ultra-Low Drop-out 500mA LDO Regulator ICs for Mobile Devices

Toshiba Corporation's Semiconductor and Storage Products Company today announced the launch of 500mA LDO regulator ICs that claim the industry's lowest-class drop-out voltage in low voltage input. Shipment starts from today. The new TCR5AM series achieve ultra-low dropout and low voltage output by adopting an external bias voltage supply (Vbat) as an extra input voltage, improving power efficiency.

It offers high-efficient LDO solutions by achieving ultra-low dropout and various protection functions, such as over-current protection and over-temperature protection, in a single high-power dissipation package. It is designed to be used in smartphones, tablets, wearable devices and other mobile devices.

Main features include: Low dropout voltage：0.072V (typical) @Vout=0.6V, Vbat=3.3V, Iout=300mA, and 0.120V (typical) @Vout=0.6V, Vbat=3.3V, Iout=500mA; Wide line-up of output voltage: VOUT = 0.55 to 3.6 V; Protection functions: Over-current protection, over-temperature protection, inrush current protection circuit, under-voltage lockout function; Output current rating of 500mA; and high-power dissipation package, PD=0.6W, 1.2 x 1.2mm, t:0.38mm.
