Toshiba to Launch CMOS-LDO Regulators for Mobile Devices
Toshiba Corporation is introducing 300mA output single LDO regulators that use a newly developed micro CMOS process to significantly improve drop-out characteristics.
In a compact 1.0mm x 1.0mm x 0.6mm DFN4 package, the new TCR3DM series achieves 140mV (typ.) at 3.0V and 300mA. The new regulators also include a high-speed load transient response circuit and low-noise circuit.
The devices are suited for use in smartphones, mobile phones, tablets, laptop PCs, digital cameras, digital video cameras and other small mobile devices.
Apart from basic functions that include over-current protection, over-temperature protection and output auto-discharge, these 300mA output LDO regulators limit inrush current and are recommended for a wide range of applications, particularly mobile devices.
Key Features
1. Low drop-out voltage
VIN-VOUT = 140mV (typ.) at 3.0V output, IOUT = 300mA
2. Low output noise voltage
VNO = 38μVrms (typ.) at 2.5V output, IOUT = 10mA, 10 Hz < f < 100kHz
3. The voltage-clamp type output voltage can be set between1.0V and 4.5V in increments of 50mV.
4. Low bias current (IB=65μA (typ.) at IOUT=0mA)
5. Excellent load transient response characteristics
ΔVOUT = ±80mV (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
