Toshiba Expands Line-up of CMOS-LDO Regulator ICs for Mobile Devices

Adds 300mA single output product with low drop-out, low output noise and high-speed load transient response in an SMV package to line-up

TOKYO — (BUSINESS WIRE) — March 13, 2013Toshiba Corporation (TOKYO:6502) has expanded its line-up of CMOS-LDO regulator ICs for mobile devices with the 300mA single output "TCR3DF Series", which delivers low drop-out, low output noise and high-speed load transient response characteristics. Samples will be available in April with mass production scheduled to start in May.

The new line-up covers a range of voltage-clamp type output voltages, from 1.0V to 4.5V, in a SMV (SOT-25: 2.9 x 2.8 x 1.1 mm) package. With additional features of inrush current limit, over-current protection, and over-temperature protection, the devices offer the high performance characteristics required in analog circuits

The new CMOS-LDO regulators are suited for use in a wide range of mobile devices, such as smartphones, mobile phones, tablets, notebook PCs, digital cameras and digital video cameras.

Applications

Mobile devices such as smartphones, mobile phones, tablets, notebook PCs, digital cameras and digital video cameras.

Key Features

1.   Low drop-out voltage

VIN-VOUT =230mV (typ.) at 2.5V output, IOUT =300mA

2. Low output noise voltage

VNO =38μVrms (typ.) at 2.5V output, IOUT =10mA, 10 Hz < f < 100kHz

3. Voltage-clamp type output voltage can be set between 1.0V and 4.5V in increments of 50mV.
4. Low bias current (IB =65μA (typ.) at IOUT =0mA)
5. Excellent load transient response characteristics

ΔVOUT = ±85mV(typ.) at IOUT = 1 ⇔ 300mA, COUT =1.0μF

6. Over-current protection
7. Over-temperature protection
8. Inrush current limit
9. Output auto-discharge
10. Pull-down control terminal connection
