New 300mA CMOS-LDO Regulator ICs for Mobile Devices

June 17, 2014

Feature Low Drop-out Voltage, Low Output Noise Voltage, Low Inrush Current


IRVINE , Calif., — Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced two new additions to its TCR3D series of 300mA single output CMOS-LDO regulator ICs. The new TCR3DMxx is housed in a small DFN4 (1.0x1.0x0.58mm) package; and the TCR3DFxx comes in a general purpose SMV(SOT-25)(2.8x2.9x1.1mm) package.

Both feature low drop-out voltage, low output noise voltage and a built-in low inrush current reduction circuit.

Toshiba offers more than 40 products with a fixed output voltage ranging from 1.0 to 4.5V to accommodate various applications , including smart phones, tablet PCs, portable audio players, digital cameras, game consoles and other small mobile devices.

CMOS-LDO regulators enable a low profile, low supply current and low dropout, making them a popular power management choice for mobile devices. Toshiba's micro CMOS process helps the regulators improve the tradeoff between characteristics and size. A small package size makes the new LDO regulators suitable for applications requiring high-density packaging, such as portable devices.


  • Low drop-out voltage: VIN-VOUT = 490 mV (typ.) at 1.2 V-output, IOUT = 300 mA
  • Low output noise voltage: (V NO = 38µVrms (typ.) at 2.5V output, I OUT = 10mA, 10Hz ≤ f ≤ 100kHz)
  • Wide range output voltage line-ups: (Configurable in a range from 1.0 to 4.5V in steps of 50mV)
  • Built-in inrush current reduction circuit
  • Over current protection
  • Thermal shut down function
  • Built-in output auto-discharge function
  • Pull down connection between CONTROL and GND
  • Small package: DFN4 (1.0 x 1.0 x 0.58mm), SMV(SOT-25)(2.8 x 2.9 x 1.1mm)
Series Output current Output voltage Package Inrush current reduction Thermal shut down Output auto-discharge Number of output voltage types
