OREANDA-NEWS. December 06, 2012. 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 x 0.79mm x 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.
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.
