Toshiba America Electronic Components Inc. (TAEC) has expanded its TCR3D series of 300mA single output CMOS-LDO regulator ICs with two additional devices. The TCR3DMxx is housed in a 1 x 1 x 0.58mm DFN4 package, while the TCR3DFxx comes in a general purpose SMV(SOT-25) (2.8 x 2.9 x 1.1mm) package.

Both feature low drop-out voltage, low output noise voltage and a built-in low inrush current reduction circuit.

Toshiba offers more than 40 products with a fixed output voltage ranging from 1-4.5V to accommodate various applications including smart phones, tablets, portable audio players, digital cameras, game consoles and other small mobile devices.

CMOS-LDO regulators enable a low profile, low supply current and low dropout, making them a popular power management choice for mobile devices. Toshiba's micro CMOS process helps the regulators improve the tradeoff between characteristics and size. A small package size makes the LDO regulators suitable for applications requiring high-density packaging such as portable devices, added the company.

The devices boast wide range output voltage line-ups: (configurable in a range from 1-4.5V in steps of 50mV), built-in inrush current reduction circuit, over current protection, thermal shut down function, built-in output auto-discharge function and pull down connection between CONTROL and GND.

Toshiba's 300mA CMOS-LDO regulator ICs are available. Budgetary pricing is $0.05 to $0.07.
