TOKYO--()--Toshiba Corporation (TOKYO:6502) will launch a 200mA output single LDO regulator fabricated with a newly developed micro-CMOS process. Its features include low-noise output, high ripple rejection ratio, excellent responsiveness under high-speed loads and low drop-out.
The new LDO regulator achieves a low-noise output of 18μVrms (2.5V output), an excellent ripple rejection ratio of 62dB at high frequency (2.5V output, f = 10kHz), excellent responsiveness under high-speed loads of ΔVOUT = ±65mV (IOUT = 1mA ⇔ 150mA, COUT = 1.0μF), and low drop-out characteristics of 80mV (2.5V output, IOUT = 100mA).
Integration into an ultra-small WCSP4 package (0.79mm × 0.79mm × 0.5mm) ensures suitability for applications demanding high-density packaging, such as mobile devices.
Samples are available now and mass production is scheduled to start in January.
Mobile phones, tablet PCs, portable audio players, digital cameras, digital video cameras and other small mobile devices
1. Low noise output
VNO = 20μVrms (typ.) at 3.0V output, IOUT = 10mA, 10 Hz < f < 100kHz
VNO = 18μVrms (typ.) at 2.5V output, IOUT = 10mA, 10 Hz < f < 100kHz
VNO = 14μVrms (typ.) at 1.2V output, IOUT = 10mA, 10 Hz < f < 100kHz
2. High ripple rejection ratio
RR = 75dB (typ.) at 2.5V output, IOUT = 10mA, f = 1kHz
RR = 62dB (typ.) at 2.5V output, IOUT = 10mA, f = 10kHz
RR = 50dB (typ.) at 2.5V output, IOUT = 10mA, f = 100kHz
3. High-speed load transient response
ΔVOUT = ±65mV (typ.) at IOUT = 1 ⇔ 150mA, COUT =1.0μF
4. Low drop-out voltage
VIN-VOUT = 80mV (typ.) at 2.5V output, IOUT = 100mA
5. The voltage-clamp type output voltage can be set between 1.2V and 3.6V in increments of 50mV.
6. Output voltage accuracy: ±1.0%
7. Built-in over-current protection circuit
8. Built-in over-temperature protection circuit
9. Ultra-small package contributes to reductions in space required.
