TCR5RG: Compact LDO Regulators for Stable Power Line Output in Smartphone and Wearable Devices

TCR5RG Series LDO Regulators
Toshiba's TCR5RG series Compact LDO Regulators

The newly launched TCR5RG series from Toshiba Electronic Devices & Storage Corporation is a group of 45 LDO regulators all housed in a thin, compact WCSP4F package. With a maximum output current of 500mA and output voltage in the range of 0.9V to 5.0V the new devices allow the users to select the output voltage best suited to their applications.


The TCR5RG series offers an industry-leading high ripple rejection ratio of 100dB that is achieved by combining a wide-gap circuit, a low-pass filter that allows only extremely low frequencies to pass, and a low-noise, high-speed operational amplifier. Apart from this the series also features low output voltage noise and high output voltage accuracy for enabling the regulators to contribute to the stabilization of power lines.


These regulators measure 0.645mm x 0.645mm and are suitable for power line applications in cameras and small devices such as smartphones and wearables requiring high-density mounting.


Features of TCR5RG Series

  • High ripple rejection ratio: R.R.=100dB (typ.) @f=1kHz
  • Low output noise voltage: VNO=5μVrms (typ.) @10Hzf100kHz
  • High output voltage accuracy :
  • VOUT min/max= -1.5/1.5% @1.8VVOUT2.8V, T= -40 to 85°C
  • VOUT min/max= -1.8/1.8% @VOUT>2.8V, T= -40 to 85°C
  • Thin and compact WCSP4F package : 0.645×0.645mm (typ.), t=0.33mm (max)
